The molecular machinery of Keilin'srespiratory chain.

Photosynthesis Research is an international journal dealing with both basic and applied aspects of photosynthesis. It covers all aspects of photosynthesis research, including light absorption and emission, excitation energy transfer, primary photochemistry, model systems, membrane components, protein complexes, electron transport, photophosphorylation, carbon assimilation, regulatory phenomena, molecular biology, environmental and ecological aspects, photorespiration, and bacterial and algal photosynthesis. The journal publishes research at all levels of plant organization: molecular, subcellular, cellular, whole plant, canopy, ecosystem and global. Manuscripts are always reviewed by recognized authorities in the field.

In this experiment we were told that we would be measuring the rate of photosynthesis.

Supporting activities include the development of epidemiological, experimental laboratory, and risk-assessment methods that could produce internationally comparable results, and the development of manpower in the field of toxicology.

Presented at the American Water Works Association Meeting, June 1981.

Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react....

Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease.

6CO + 6H O ® C H O + 12O (in the presence of light energy and chlorophyll) Aim- The aim of the experiment is to determine what effect light intensity has upon the rate of photosynthesis of Canadian Pondweed (Elodea)....



Conclusion

I have realised in this experiment that without the products of
photosynthesis all living organisms would die, including plants as
eventually the limiting factors would run out such as carbon dioxide.

The word equation for photosynthesis is: Light [IMAGE]Carbon Dioxide + Water Glucose + Oxygen Chlorophyll Although most of the glucose produced is converted into insoluble starch for storage in the stem, leaves or roots, some is used immediately by the plant to provide via respiration....

Respiration and Photosynthesis Lab Report - Scribd

For photosynthesis to occur, plants need: · Light energy from the sun · Chlorophyll to absorb light energy · Carbon dioxide from the atmosphere and from respiration in plant cells · Water which is absorbed by the roots and transported to the leaves by the xylem tubes....

Respiration and Photosynthesis Lab Report AP Biology Abstract

The atmospheric lifetime is fairly short relative to the inter-hemispheric transport time of 1 to 1.5 years, resulting in higher concentrations of methylene chloride in the northern hemisphere, where most of the emissions occur at present. Methylene chloride is expected to have no significant impact on stratospheric ozone depletion.
