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: -Plants respire through stomata. Stomata are the small openings (pores) present on the leaves, stems, and other organs of a plant. The small opening of the stomata is guarded by two guard cells that help in opening and closing stomata for gaseous exchange with the atmosphere.
Detailed explanation-3: -The correct option is B False. Photosynthesis & Respiration in plants: Plants breathe at all times of the day and night. Photosynthesis and respiration occur throughout the day, whereas only respiration and dark processes occur at night.
Detailed explanation-4: -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.
