Detailed explanation-1: -Carbon dioxide enters the leaves through tiny pores present on the surface of the leaves called stomata. Note: Photosynthesis occurs during the day time. Thu stomata are open mostly throughout the day for supplying the carbon dioxide to the plants. Respiration occurs throughout day and night.
Detailed explanation-2: -Carbon dioxide It moves by diffusion through small holes in the underside of the leaf called stomata. Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or dry conditions. The lower part of the leaf is a spongy layer with loose-fitting cells.
Detailed explanation-3: -Stomata are the small pores present on the leaves of the plant. Carbon dioxide enters the plants through these openings.
Detailed explanation-4: -Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food.
