WebIn plants, carbon dioxide ( \text {CO}_2 CO2) enters the interior of a leaf via pores called stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions, where sugar is synthesized. These reactions are also called the light-independent … WebMay 14, 2024 · C 4 Plants Over 8,000 species of angiosperms have developed adaptations which minimize the losses to photorespiration. They all use a supplementary method of CO 2 uptake which forms a 4-carbon molecule instead of the two 3-carbon molecules of the Calvin cycle. Hence these plants are called C 4 plants. WebIn 1966, Hatch and Slack discovered the C4 cycle, hence the name. It is also referred to as the ß-carboxylation pathway and co-operative photosynthesis. The 4-carbon oxaloacetic acid is the first stable compound of the Hatch and Slack cycle, hence is called the C4 cycle. C4 plants are plants possessing a C4 cycle. difference between hybrid and smart hybrid
