Question

How is CO2 obtained by a) aquatic plants b) terrestrial plants?

Answer 1

Terrestrial plants are with leaves having tiny pores on their surface, called stomata. The stomata contain guard cells that regulate the opening and closing of the stomata. They are opened only when the plant needs carbon dioxide for photosynthesis.
Aquatic plants obtain only little amount of carbon dioxide. They are adapted to the limittion of carbon dioxide. It is the dissolved form of carbon dioxide on which the aquatic plants depend on for performing photosynthesis
