Transpiration Welcome to your Transpiration 1. Transpiration pull will be maximum under which of the following conditions? Open stomata, dry atmosphere and moist soil Open stomata, high humid atmosphere and well irrigated soil Open stomata, high humid atmosphere and dry soil Closed stomata, dry atmosphere and dry soil2. 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 protein content of the cells The turgid and flaccid state of the guard cells3. Transpiration is very low during the storms due to None of the above Presence of moisture in the wind High velocity of wind Low temperature during storms4. With decrease in atmospheric pressure, the rate of transpiration will decrease rapidly decrease slowly remains the same increase5. In hot summer days, plant cooling is due to Loss of water from entire plant Loss of water vapour from leaves Loss of liquid water Transport of water in plant6. Guttation is the elimination of excess of water from plants through Stomata Hydathodes Lenticels Wounds7. Plants lose water by guttation when Soil is wet and and the atmosphere is humid Soil is wet and and the atmosphere is dry Soil is dry and and the atmosphere is dry Rate of transpiration is high8. Most of the transpiration in tall trees occurs through Stomata Bark Cuticle Lenticels9. Stomata open during the day and close at night because Enzymes convert starch into sugar at elevated pH in night Loss of starch in day time raises OP of subsidiary cells Loss of sugar increases osmotic concentration of the cell sap Photosynthesis occurs during day time only10. 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 be killed instantly Grow more vigorously because more energy will be available Stop growing and gradually die of starvation11 out of 10Please fill in the comment box below.
