Web2. Stomata, regulated by guard cells, allow gases to pass in and out of the leaf. We may not be able to see them with the naked eye, but the leaves of plants contain tons of tiny holes, or pores, called stomata (sing. stoma). They play a central role in photosynthesis, allowing carbon dioxide to enter the leaf and oxygen to exit the leaf. WebThe upper part of the leaf is where the light falls, and it contains many cells called palisade cells. This has many chloroplasts, with lots of chlorophyll to trap as much light as possible.

"WebStomata, the pores on the leaf epidermis, facilitate gas exchange in plants. Plants balance their CO 2 demands and water losses through the adjustment of stomatal size, density, and modulation (opening and closing of stomata); however, adjustments to stomatal size and density are only possible during stomatal ontogeny. Consequently, stomatal size and … " - Parts of the stomata

WebStomata: Stomata (sing.-stoma) are very minute openings found in the epidermal layer of leaves, stem and other aerial parts of the plant. Each stoma remains surrounded by two kidney-shaped or bean-shaped cells called guard cells. Chloroplasts are … WebTranspiration. Water moves into root hair cells by osmosis down a water potential gradient and is transported to different parts of the plants in the xylem.Water near the surface of the leaf evaporates, becoming water vapour and exiting the leaf through the stomata.When this happens water is drawn up from the xylem to replace the water lost from the leaves.
