Detailed explanation-1: -The gas exchange in plants takes place through stomata, and the process is called diffusion. The stomata are found in all the aerial plants and not in the roots. Epidermal cells present in the stomata surrounding the guard cells of the stoma are called subsidiary cells.
Detailed explanation-2: -Each stoma is made of two guard cells. When these guard cells are swollen with water, they create an opening between them, the stomatal pore. Gas exchange occurs via the pore. When the guard cells are flaccid they lay close together, thus closing the stomatal pore.
Detailed explanation-3: -The exchange of gases through stomata takes place by the process of diffusion.
Detailed explanation-4: -Final answer: Diffusion of gases in plants occurs through stomata, lenticels, and intercellular spaces.
