Investigating Factors Affecting the rate of photosynthesis.

Potassium is known to be extracted from the xylem and re-exported via the phloem (Section 5.1). In leaves, the concentrated sap flowing through the narrow xylem vessels of fine veins is separated from sieve tubes of the phloem by only two or three parenchyma cells, frequently enhanced by transfer cells. Exchange from xylem to phloem is probably made by this direct path. Solutes travel in the phloem back to stems, either distally to younger developing leaves and the stem apex or proximally towards roots.

6CO + 6H O = C H O + 6O The factors that effect the rate of photosynthisis are the amount of light, the amount of carbon-dioxide (CO ) and the temperature that can be used by the plant....

Investigation into the Factors Affecting The Rate Of Photosynthesis.

Introduction: "Photosynthesis is the conversion of light energy to chemical energy that is stored in glucose or other organic compounds; it occurs in plants, algae, and certain prokaryotes" (Campbell, G-16).

Photosynthesis need light to work, so light therefore should speed up the rate of photosynthesis.

Free rate of photosynthesis Essays and Papers - …

Photosynthesis can be treated with a top-down approach starting with gross primary productivity and relating the process to world food production and the base of food chains, or from a bottom-up perspective starting with the cell, chloroplast and biochemical detail. Experiments can come first to devise first principles about the factors necessary for and affecting the rate of photosynthesis, or can be used to reinforce theory. Experimental work can either use whole plants (e.g. Elodea in a photosynthometer) or plant parts (e.g. leaf discs) or cell free systems (e.g. Hill reaction) or manufactured units (e.g. immobilised algae balls).
