Stoma in a tomato leaf shown via colorized scanning electron microscope image A stoma in horizontal cross section The underside of a leaf. In this species (Tradescantia zebrina) the guard cells of the stomata are green because they contain chlorophyll while the epidermal cells are chlorophyll-free and contain red pigments.
English: Opening and Closing of Stomata 1-Epidermal cell 2-Guard cell 3-Stoma 4-K+ ions 5-Water 6-Vacuole a. Open stoma: stomata are the small pores in the epidermis of leaves. They are bordered by guard cells. The stomata open when the turgor pressure increases in the guard cells, causing the cells to buckle outward.
English: Opening and Closing of Stoma. As K+ levels increase in the guard cells, the water potential of the guard cells drops, and water enters the guard cells ...
Guard cells have cell walls of varying thickness(its inner region, adjacent to the stomatal pore is thicker and highly cutinized [7]) and differently oriented cellulose microfibers, causing them to bend outward when they are turgid, which in turn, causes stomata to open. Stomata close when there is an osmotic loss of water, occurring from the ...

English: C3 and C4 plants(1) stomata stay open all day and close at night. CAM plants(2) stomata open during the morning and close slightly at noon and then open again in the morning. CAM plants(2) stomata open during the morning and close slightly at noon and then open again in the morning.
Original – Opening and Closing of Stoma. As K+ levels increase in the guard cells, the water potential of the guard cells drops, and water enters the guard cells. Reason It has a high educational value, as it also shows the parts of Guard cells.
