Tiny pores are found on the surface of the leaves of plants. These pores are calledstomata. These stomata surrounded by the kidney shaped guard cells provide manyvital functions to the plants.Which of the following functions is not served by the stomata for the plants?(A) Exchange of gases, particularly CO2 and O2, with atmosphere(B) Loss of water in the form of vapours during transpiration(C) Helps to create pressure for the water to rise upward, by its process oftranspiration.

What are the functions of stomata and guard cells, and what would happen to a plant if these cells did not function correctly?Group of answer choicesStomata allow gases to enter and exit the plant. Guard cells regulate the opening and closing of stomata. Photosynthesis and, in turn, transpiration, would not occur which is necessary to maintain a continuous flow of water upwards from the roots to the leaves.Guard cells allow carbon dioxide to enter and exit the plant. Stomata regulate the opening and closing of guard cells. Transpiration and in turn, photosynthesis would not occur which is necessary to maintain a continuous flow of water upwards from the roots to the leaves.Stomata allow oxygen to enter and exit the plant. Guard cells regulate the opening and closing of stomata. If the cells didn’t function, photosynthesis would continue but transpiration would cease, which would interfere with the necessary continuous flow of water upward from roots to leaves.Guard cells allow carbon dioxide to enter and exit the plant. Stomata regulate the opening and closing of guard cells. If the cells didn’t function, photosynthesis and transpiration would cease, which would interfere with the necessary continuous flow of water upward from roots to leaves.

What are stomata in plants?A.Tissues that transport water throughout the plant.B.Openings that allow gas exchange to occur.C.Pigments that capture the energy of sunlight.D.Nutrients that surround plant embryos in seeds.

Underneath the leaves, there are very small holes called (stomata/cuticles) that allow air to get inside9. (Stomata/Cuticles) is a waxy coat that help plants keep water inside10. Inside the plant, there are tubes of dead cells called (xylem, phloem) that help transport water and minerals up and down the plant.11. Inside the plant, there are tubes of living cells called (xylem, phloem) that help transport sugars to areas of the plant that need it.12. The flower part called ‘sepal’ is usually (green/yellow) in colour

What is transpiration in plants?The movement of water through the phloem cellsThe movement of water through a plant due to evaporation from the leavesThe absorption of water by the root hair cellsThe absorption of water through the leaves2Which substances enter and leave the plant through the stomata?Carbon dioxide enters; water and oxygen leavesWater and oxygen enter; carbon dioxide leavesOxygen enters; carbon dioxide and water leaveCarbon dioxide and water enter; oxygen leaves3Which cells control the opening and closing of the stomata?Guard cellsPhloem cellsPalisade cellsXylem cells4What happens to the rate of transpiration when the temperature is increased?It increasesIt decreasesIt stops altogetherIt stays the same5Why does the rate of transpiration decrease in very humid conditions?Because there will be less water inside the leaf than in the airBecause the rate of photosynthesis increasesBecause the rate of photosynthesis decreasesBecause there will be more water inside the leaf than in the air 6Why are stomata normally found on the underside of leaves?So that they are nearer the ground So that they are protected from rainSo that they are shaded from the sunTo allow water to escape from the leaves by gravity

What is the function of stomata? Which cells open and close the stomata?
