Detailed explanation-1: -Stomata, as mentioned above, are the structures through which gas exchange occurs in leaves. Each stoma is surrounded by two guard cells, which can open and close depending on environmental conditions.

Detailed explanation-2: -Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores-called stomata-to take in carbon dioxide and release oxygen.

Detailed explanation-3: -Stomata facilitate not only the uptake of CO2 but also the exchange of all gases between the aerial parts of the plant and the atmosphere.

Detailed explanation-4: -During photosynthesis, leaves take in atmospheric CO2 and release O2 through stomata, microscopic pore structures in the leaf epidermis (singular = stoma). A pair of guard cells surrounds each stoma, and these cells control the opening and closing of the stomatal pore between them.

Detailed explanation-5: -What is the difference between stroma and stoma? Stroma is the colourless matrix present in the membranes of the chloroplast, whereas stoma is a pore-like structure that helps in gaseous exchange.
