DENDROLOGY

Detailed explanation-1: -C3 plants are defined as plants that exhibit the C3 pathway. These plants use the Calvin cycle in the dark reaction of photosynthesis. The leaves of C3 plants do not show Kranz anatomy. Here the photosynthesis process takes place only when the stomata are open.

Detailed explanation-2: -The majority of plant species on Earth uses C3 photosynthesis, in which the first carbon compound produced contains three carbon atoms.

Detailed explanation-3: -The majority of plants and crop plants are C3 plants, referring to the fact that the first carbon compound produced during photosynthesis contains three carbon atoms. Under high temperature and light, however, oxygen has a high affinity for the photosynthetic enzyme Rubisco.

Detailed explanation-4: -All plants use C3 photosynthesis, which has been supplemented in some species with Crassulacean acid metabolism (CAM) and C4 photosynthesis. These two pathways are adaptations to dry environments.

Detailed explanation-5: -C3 photosynthesis occurs via the Calvin cycle. C3 plants open their stomata during the day. Excessive water loss through the stomata can be detrimental to a plant which is why C3 plants thrive in cool, wet climates.
