Transpiration Welcome to your Transpiration 1. If the rate of transpiration becomes more than the rate of photosynthesis, plants will be killed instantly Grow more vigorously because more energy will be available Stop growing and gradually die of starvation Continue to live, but will not be able to store food2. Transpiration pull will be maximum under which of the following conditions? Open stomata, high humid atmosphere and dry soil Open stomata, dry atmosphere and moist soil Open stomata, high humid atmosphere and well irrigated soil Closed stomata, dry atmosphere and dry soil3. Guttation is the elimination of excess of water from plants through Lenticels Stomata Wounds Hydathodes4. Most of the transpiration in tall trees occurs through Stomata Lenticels Bark Cuticle5. Transpiration is very low during the storms due to Presence of moisture in the wind High velocity of wind Low temperature during storms None of the above6. Plants lose water by guttation when Soil is wet and and the atmosphere is dry Rate of transpiration is high Soil is dry and and the atmosphere is dry Soil is wet and and the atmosphere is humid7. In hot summer days, plant cooling is due to Transport of water in plant Loss of water vapour from leaves Loss of liquid water Loss of water from entire plant8. With decrease in atmospheric pressure, the rate of transpiration will remains the same increase decrease slowly decrease rapidly9. Stomata open during the day and close at night because Photosynthesis occurs during day time only Loss of sugar increases osmotic concentration of the cell sap Loss of starch in day time raises OP of subsidiary cells Enzymes convert starch into sugar at elevated pH in night10. In the mechanism of opening and closing of stomata, the important factor is The starch content of the cells The presence of Chloroplast in the guard cells The turgid and flaccid state of the guard cells The protein content of the cells11 out of 10Please fill in the comment box below.
