Materials and Methods Procedure is found on pages 258 to 259 in Biology I: Molecular and Cells Laboratory Manual (Dalton, 2012). Results "1" represents the first trial, with an average time-to-surface of 282.4 seconds at a distance of seven centimeters from the light source. "2" represents the second trial, with an average time-to-surface of 422.9 seconds at a distance of four centimeters from the light source. Conclusion An autotroph is an organism that uses sunlight and/or

The hypothesis here is that it is the quality of the light, not the quantity of the light that makes a difference, and having a lot more light will not necessarily make photosynthesis occur any faster. Discussion With an experiment like this there is always room for error. Measurements taken incorrectly is the biggest problem, because there are multiple steps to be taken each time the light source is moved, and

Photosynthesis is a process in plants, algae, and some prokaryotes, that coverts solar insulation into chemical energy stored in glucose or other organic compounds. Photosynthesis occurs in slightly different ways in higher plants relative to photosynthetic bacteria. Photosynthesis is an important process because it harnesses the sun's energy into utilizable forms of energy on earth. Most biological organisms such as animals and fungi are unable to directly use light energy

Photosynthesis is critical for the survival of all life on earth. The process of photosynthesis within plants consists of two processes, one which begins with energy from the sun in the form of visible light, and another which is light-independent and capture carbon dioxide for glucose production (Audesirk, Audesirk, & Byers, 2008). Plants are green because they absorb the red and blue wavelengths of visible light, thereby reflecting the color green

The entire unit is known as a photosytem and in green plants, one finds two of these systems, photosystem I and photosystem II, both of which are involved in the light reactions of photosynthesis. Light energy absorbed by these pigments of the antenna complex is "passed to the reaction center chlorophyll molecules from which it passes along an electron-transport chain" (Blankenship, 215). Photosystems II contains a kind of chlorophyll a

The fact is that numerous rooted macrophyte structures are not full of naturally strong and healthy particles and sediments and nutrients. It is because of the restriction or absence of these particles, sediments and nutrients that the study of these systems has not been as extensive and thorough as the concentration on the terrestrial structures when understanding the fate, sources and sinks of Co2 levels in the ecosystems and the
