What is meant by C4 plants?
In green plants in light independent phase of photosynthesis there are three pathways of CO2 reduction. One of it is Hatch and Slack cycle or C4 pathway. The first stable substance formed in the pathway is 4 - carbon Oxaloacetic acid. In C4 plants, at the same time both the Hatch and Slack cycle and the Calvin cycle are carried out. The rate of photosynthesis in C4 plants is higher than that of in C3 plants. Some examples of C4 plants are maize, sugarcanes, other plants of grass type, motha grass and amaranthus.
