Question #7b1d4

Answer 1

See answer below

Explanation:

Photosynthesis is a chemical reaction that occurs in the mesophyll cells in the leaves of plants (mainly palisade mesophyll), in which chlorophyll absorbs light energy and converts it to chemical energy used to synthesise glucose from carbon dioxide and water. Oxygen is also released in the process.

Water and carbon dioxide are the raw materials for photosynthesis. Water is obtained through absorption from the soil solution via root hair cells, which travels up the xylem via transpiration pull and reaches the mesophyll cells via osmosis across cells after water molecules leave the xylem. Carbon dioxide is obtained by diffusion from the atmosphere to the intercellular air spaces in the leaves through the stomata. Carbon dioxide then dissolves into the film of moisture surrounding the cells and diffuses into mesophyll cells.
