Detailed explanation-1: -leaf, in botany, any usually flattened green outgrowth from the stem of a vascular plant. As the primary sites of photosynthesis, leaves manufacture food for plants, which in turn ultimately nourish and sustain all land animals. Botanically, leaves are an integral part of the stem system.
Detailed explanation-2: -The Process of Respiration in Plants Leaves possess stomata – tiny pores, for gaseous exchange. The oxygen consumed via stomata is used up by cells in the leaves to disintegrate glucose into water and carbon dioxide.
Detailed explanation-3: -Plant breathe through tiny openings in leaves known as stomata. Stomata functions by opening and closing for the intake of carbon dioxide as well as releasing oxygen. The oxygen from the air enters the leaf through the stomata and reaches all the cells through diffusion.
Detailed explanation-4: -Respiration occurs in the presence of oxygen to form water and carbon dioxide to breakdown glucose and release energy. Respiration does not require sunlight and chlorophyll, photosynthesis requires these. Therefore this statement is false.
