Question

If carbon dioxide is needed for photosynthesis and water is plentiful, which of the following is likely to occur?

Answer 1

The right answer is D

The stomata are at the level of the epidermis of the leaves and aerial stems, the place of passage of the gases (carbon dioxide, oxygen, water vapor) which play a fundamental role in the physiology of the plant. These structures (which can be considered as "mini-organs") interactively regulate these exchanges. They are the terrestrial plants that constitute the true interface between the external atmosphere and the internal gas network.
