The rate of photosynthesis in plants depends ..
Photosynthetic carbon metabolism encompasses the processes by which plants and other photosynthetic organisms use the energy captured from light in the form of NADPH and ATP to convert atmospheric carbon dioxide into carbohydrates. Carbohydrates produced by photosynthesis form the base for the nutrition of all other life as well as serving as the starting materials for fibres, oils and many other natural compounds used by people.
Plant photosynthesis Photosynthesis in ..
The fundamental principle of photosynthesis is that plants open and close the stomata (pores) on the leaves, and thus control the amount of carbon dioxide and oxygen that passes through them.
Photosynthesis - Science & Biology
C4 plants almost never saturate with light and under hot, dry conditions much outperform . They use a two-stage process were CO2 is fixed in thin-walled mesophyll cells to form a 4-carbon intermediate, typically malate (malic acid). The reaction involves phosphoenol pyruvate () which fixes CO2 in a reaction catalyzed by PEP-carboxylate. It forms oxaloacetic acid (OAA) which is quickly converted to malic acid. The 4-carbon acid is actively pumped across the cell membrane into a thick-walled bundle sheath cell where it is split to CO2 and a 3-carbon compound.

Cell walls: provide structural and mechanical support, protect cells against pathogens, maintain and determine cell shape, control the rate and direction of growth and generally provide form to the plant.
