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

Transpiration is the  of water from the surfaces of mesophyll cells into the air spaces, followed by the  of water vapour through stomata.

with reference to the cells and region describe the process of transpiration in plants

Transpiration in the plants occurs through which of the following ?1 pointHydathodesEpidermisStomataleaflets

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.
