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

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

Transpiration mainly occurs fromRootStemFlowerLeaf

1What is transpiration in plants?The absorption of water by the root hair cellsThe absorption of water through the leavesThe movement of water through a plant due to evaporation from the leavesThe movement of water through the phloem cells2Which substances enter and leave the plant through the stomata?Oxygen enters; carbon dioxide and water leaveCarbon dioxide and water enter; oxygen leavesWater and oxygen enter; carbon dioxide leavesCarbon dioxide enters; water and oxygen leaves3Which cells control the opening and closing of the stomata?Palisade cellsPhloem cellsGuard cellsXylem cells4What happens to the rate of transpiration when the temperature is increased?It stays the sameIt increasesIt decreasesIt stops altogether5Why does the rate of transpiration decrease in very humid conditions?Because there will be more water inside the leaf than in the air Because the rate of photosynthesis increasesBecause the rate of photosynthesis decreasesBecause there will be less water inside the leaf than in the air6Why are stomata normally found on the underside of leaves?So that they are shaded from the sunSo that they are nearer the ground So that they are protected from rainTo allow water to escape from the leaves by gravity
