Transpiration Welcome to your Transpiration 1. Transpiration is very low during the storms due to Low temperature during storms None of the above Presence of moisture in the wind High velocity of wind2. Most of the transpiration in tall trees occurs through Lenticels Bark Cuticle Stomata3. If the rate of transpiration becomes more than the rate of photosynthesis, plants will Continue to live, but will not be able to store food Stop growing and gradually die of starvation be killed instantly Grow more vigorously because more energy will be available4. In hot summer days, plant cooling is due to Loss of liquid water Loss of water vapour from leaves Transport of water in plant Loss of water from entire plant5. Plants lose water by guttation when Soil is dry and and the atmosphere is dry Rate of transpiration is high Soil is wet and and the atmosphere is humid Soil is wet and and the atmosphere is dry6. Guttation is the elimination of excess of water from plants through Lenticels Stomata Hydathodes Wounds7. Stomata open during the day and close at night because Loss of starch in day time raises OP of subsidiary cells Enzymes convert starch into sugar at elevated pH in night Loss of sugar increases osmotic concentration of the cell sap Photosynthesis occurs during day time only8. In the mechanism of opening and closing of stomata, the important factor is The protein content of the cells The starch content of the cells The turgid and flaccid state of the guard cells The presence of Chloroplast in the guard cells9. With decrease in atmospheric pressure, the rate of transpiration will increase decrease rapidly decrease slowly remains the same10. Transpiration pull will be maximum under which of the following conditions? Open stomata, dry atmosphere and moist soil Closed stomata, dry atmosphere and dry soil Open stomata, high humid atmosphere and well irrigated soil Open stomata, high humid atmosphere and dry soil11 out of 10Please fill in the comment box below.
