Plant Cell
PAGES 1 WORDS 444

Plant Cell and describes the structure & function of each part
Parts of a Plant Cell:

Cell Wall'

Protoplast': is bounded by a Cell Membrane and contains Cytoplasm, which consists of:

Vacuoles

Organelles (consists of Plastids, Mitochondria, Ribosomes, Golgi Apparatus & Endoplasmic Reticulum)

Nucleus

Structure and Functions of Each Part

Cell Wall: The Cell Wall is composed mainly of Cellulose whose molecules are joined together in fibrils as layers and contains openings to make it permeable. Most Cell Walls also contain lignins, which add rigidity, and waxes, such as cutin and suberin, which reduce water loss from cells. Its main function is to protect the cellular contents, and provide structural support to the plant. It is also involved in transport, absorption, and secretion during a plant's life cycle.

Vacuole: Vacuoles are cavities filled with cell sap and bounded by a membrane. The cell sap is made up of water containing various dissolved sugars, salts, and other chemicals. Its….

Photosynthesis 1231
Plant Cell and Solar Cell: Similarities and Differences

Photosynthesis is that process by which plants harness the solar energy for producing food. These cells help the plants to trap energy from the daylight. This trapped light is converted into other constituents that are then used by the plant to manufacture food. The additional components such as oxygen are released to the atmosphere. After these processes, the light energy is converted to chemical energy. The modern science has been able to develop technologies containing semiconductors that have solar cells. The solar energy is trapped and is converted to electricity by these solar cells (Haile & O'Connell, 2005).

The semiconductors and photosynthesis have some similarities and dissimilarities. As far as the similarities are concerned, their aim is to harness the solar energy. While plants use photosynthesis to lock in energy from the sun for manufacturing food, semiconductors trap solar energy to convert it….

Wound Healing in Plant Cells
PAGES 13 WORDS 3770

he RHDl gene product appears to be necessary for proper initiation of root hairs, whereas the RHDS, RHD3, and RHD4 gene products are required for normal hair elongation. hese results demonstrate that root hair development in Arabidopsis is amenable to genetic dissection and should prove to be a useful model system to study the molecular mechanisms governing cell differentiation in plants.(Schiefelbein & Somerville, 1990, p.235)
he genetic analysis of root hair development has identified several genes that are required for the initiation and growth of the root hair. RHL1, RHL2, and RHL3 genes are active during the formation of a bulge early in root hair growth. RHL1 encodes a nuclear protein of unknown function that is required for the formation of the polarized outgrowth. RHD6 activity is necessary to localize the site of hair initiation in the trichoblast. RHD6 acts through an auxin/ethylene pathway, as the rhd6 mutant phenotype can….

The Events of Meiosis and the Importance of Prophase 1

Generally, meiosis has two divisions of events. Each constitutes 4 phases of same names but of different division number. They are prophase, metaphase, anaphase, and telophase. From Meiosis of Access Excellence, the events in meiosis can be summarized as the following.

Prophase 1 - chromosomes duplicate into a pair of chromatid. Later, exchanging of fragments or crossing-over may occur.

Metaphase 1 - aligning of chromosome pairs at the center of the cell.

Anaphase 1 - separation of homologous pairs to opposite poles of the cell.

Telophase 1 - homologous pairs separate and forms two daughter cells

Prophase 2 - no replication of DNA

Metaphase 2 - aligning of chromosomes at the center of each cell

Anaphase 2 - the chromatids separate moving to opposite cell direction

Telophase 2-4 cells are formed each containing one chromosome.

Prophase 1 is essential because it is….

Cells are known as the basic units of life. One thing that plant cells and solar cells have in common is that they are very important to humans and living things on earth. One main difference between plant cells and solar cells is how each harnesses solar energy. Plants harness solar energy to use photosynthesis. Solar cells harness solar energy to convert it to electricity.
One of the main duties of photosynthesis is changing solar energy into chemical energy. Anything that can be digested and all fossil fuels are products of photosynthesis. Many organisms are responsible for carrying out photosynthesis. Organisms carry out this task by converting CO2 or carbon dioxide to organic material. The outcome of this chemical reaction is electrons that are converted to protons and oxygen. The remaining energy from this chemical reaction is then absorbed by carotenoids and chlorophylls.

Solar cells are composed of many semiconducting materials. The….

Eukaryotic Cells
PAGES 4 WORDS 1477

Eukaryotic Cell vs. Prokaryotic Cell:
There are two types of cells found, that originate from a common ancestor - The prokaryotes and eukaryotes. While Prokaryotes are organisms without a cell nucleus and other membrane-bound organelles and are mostly unicellular, but some exceptions are found. In contrast Eukaryotes have their cells have complex structures by internal membranes and a cytoskeleton. The principal membrane bound structure is the nucleus. All animals, plants, fungi, and protists are eukaryotes. (Diffen, 2013) Prokaryotes were the only form of life on Earth until the more complex eukaryotes evolved from them.

Differences between eukaryotic and prokaryotic cells:

The distinctions between these two types of cells create the differences in organisms Thus the groups of organisms that belong basically to the prokaryotes are non-membranous and in contrast the eukaryotes contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Though this is the basic difference, the presence of mitochondria,….

On average, male skeletons are larger than female skeletons, but just as some women are larger than some males, this distinction does not hold firm in all instances. Female pelvic regions tend to be wider than male pelvic regions, an evolutionary feature that has made childbirth easier. Female bones tend to be thinner and less dense than male bones, and thus the female skeleton tends to be lighter than male skeletons.
The skull is one of the most notable sites of difference between male and female skeletons. The teeth of males tend to be larger, and above their eye sockets men tend to have a more visible brow ridge while women often have none. The male skull tends to have a squarer (as opposed to a pointed) chin and is more angular in its demarcations than the female skull. Women's nose openings are more apt to be pointed, rather than….

Kumar, G.B.S., Ganapathi, TR. Bapat, V.A. Revathi, C.J. & K.S.N. Prasad. (2002). Expression
of Hepatitis B surface antigen in transgenic banana plants and NT- I cell line of tobacco. BARC. Retrieved from: http://barc.gov.in/publications/nl/2003/200310-12.pdf

ne of the most difficult and intractable health issues worldwide is that of Hepatitis B The disease is difficult to treat and potentially deadly. "There are about 350 million chronic carriers in the world and it is estimated that 75- 100 million of them will die of liver cirrhosis and/or hepatocellular carcinoma" (Kumar, Ganapathi, Bapat, Revathi, Prasad 2002:85). Although vaccinations do exist, the injectable form of the vaccine is expensive and has been difficult to distribute throughout the developing world where Hepatitis B is most prevalent. Injectable vaccines also require trained healthcare professionals to disseminate. There is also the risk of needle contamination in unsanitary conditions, again, making vaccines in the developing world potentially more dangerous. Cold storage is….

Cell Layout
PAGES 3 WORDS 1021

Operation Management
What type of layout would you use for the assembly of a television set? What are the reasons for this choice?

A product layout would be best suited for the assembly of a television set. Televisions sets, in general, are commodity products with very little differentiation between product classes. In many instances a Sony 32-inch high definition television will have many of the same components as the Sony 40-inch high definition television set. Conversely, auto manufacturers often use the same parts on similar vehicle types.

In regards to a television set, companies often mass produce these items to achieve economies of scale. Manufactures, such as those that create televisions, often have very high fixed costs associated with property, plant, and equipment. As such, the more television that are produced the cheaper on a per unit basis each television is. The manufacturer therefore has incentive to product a wide array of televisions….

Cell is important because it is the building block of the body. It is a replicating organism that has proteins and cytoplasm and nucleic acids inside a membrane Alberts (2002). Cells are in everything from humans to plants, though each representation of life has its own particular cells. Cells are very small and impossible to see with a microscopic lens. That is why the cell was not actually noticed until such technology came along in the 17th century. Indeed, the name cell, which means small room in Latin, comes from the discoverer of the cell, who thought they looked like the small rooms that monks in the medieval era used to live in, which were called cells (Karp, 2009). Essentially, all living organisms are made up of cells and if there were no cells there would be no life. So the cell is very important.
What do cells do? That depends….

Fuel Cells in Green Engineering
The energy tomorrow is beginning to be available today. Fuel cells, which just a very few years ago were a pipe dream, are becoming g a reality, and they are used in areas ranging from space exploration to toy motivation (Joy). The promise of the fuel cell can be seen in the fact that they use the most abundant source of energy on the planet, Hydrogen atoms (Birch). They are also being seen as the energy savior because they emit a common, non-toxic waste which can also be utilized as a saving grace around the globe, water (Joy; Patturaja). A fuel that uses the most abundant element on the planet and emits clean, pure water does seem like science fiction, but there are already being used with it as a motive force.

The space shuttle has always been powered by hydrogen fuel cells (Joy). Although they are….

Fuel Cell the Study Focuses
PAGES 15 WORDS 4499


Different Fuel Cell Technologies

U.S Department of Energy (2010) provides the description of different fuel cell technologies. The fuel cell technologies are differentiated according to their efficiency, operating temperatures, costs and application. The classifications are based on 6 major groups:

Alkaline fuel cell (AFC),

Phosphoric acid fuel cell (PAFC),

Solid oxide fuel cell (SOFC),

Molten carbonate fuel cell (MCFC),

Proton exchange membrane fuel cell (PEMFC);

Direct methanol fuel cell (DMFC).

Alkaline fuel cell (AFC)

The AFC generates electrical power using alkaline electrolyte KOH (potassium hydroxide) in water-based solution. The presence of hydroxyl ions within the electrolyte allows a circuit to extract electric energy. The illustration in Fig 2 reveals an alkaline fuel cell. As being revealed in Fig 2, two hydrogen gas molecules combines with 4 hydroxyl ions have a negative charge to release 4 electrons and 4 water molecules. The equation 4 reveals the reaction of oxidation that takes place. (Mark, 2003).

Equation (4)

Dimitrios Karussis and Ibrahim Kassis, in the article, "Use of Stem Cells for Treatment of Multiple Sclerosis," conclude,
"In the current review, the various types of stem cells, which were mainly studied in animal models, will be reviewed as a potential therapeutic approach for MS. The main and common mechanisms of action of all stem cells include induction of neuroregeneration and remyelination through the activation of resident stem cells, or production of new CNS cell lineage progenitors, paralleled by local and systemic immunomodulating effects" (Karussis & Kassis, 2007, Conclusion ¶).

The other diseases that are showing promise in treatments resulting from stem cells usage includes: as cancer, diabetes, osteopetrosis, rheumatoid arthritis, Alzheimer's disease, Parkinson's disease, spinal cord injuries, heart disease, immune system disorders, blood disorders; the list goes on (Diseases Treated by Cord lood, 2010).

Conclusion

Stem cells are a valuable weapon in the future treatment of disease and in drug testing. The….

Family Background Plant, Breeding History Plan
isconsin fast plants were developed in the mid-1980's by professor Paul illiams as a way of enabling individuals to study the life cycle of plants in a relatively short period of time. isconsin fast plants are of the brassica rapa species, and are ideal for short-term studies because they develop celeritously over a life cycle which is completed within a year's time. They typically bloom in the winter. Although there are many different varieties of brassica rapa (which includes strains such as brassica rapa ssp. campestris L., brassica rapa ssp. sarson and others) (Itis), they are all part of the family known as cruciferae. These plants look like many types of vegetables including mustards, turnips and cabbage. Virtually all of the plants in this family have four petals that cross one another similar to a crucifix, which is where the name of this family….

The price charged for the company's biodiesel product lines will be tied to the prevailing prices charged for feed stock and production costs, but any costs in excess of traditional diesel fuel alternatives will be offset by marketing initiatives designed to promote the environmentally responsible aspects of the products' use, as well as the patriotic aspects of reducing America's reliance on foreign oil.
Distribution (Place). Transportation for the company's product line will be outsourced.

Promotion. As noted above, biodiesel products possess a number of characteristics that can be promoted to different industries and organizations depending on their specific needs. Larger enterprises such as Universal Studios Theme Park could be encouraged to use biodiesel alternatives based on the tax advantages and public relations opportunities such use affords; likewise, governmental agencies could reap economies of scale by converting large vehicle fleets to biodiesel applications and also enjoy the P benefits that accrue to….
