Transpiration Welcome to your Transpiration 1. If the rate of transpiration becomes more than the rate of photosynthesis, plants will Stop growing and gradually die of starvation Continue to live, but will not be able to store food Grow more vigorously because more energy will be available be killed instantly2. Transpiration pull will be maximum under which of the following conditions? Open stomata, high humid atmosphere and dry soil Open stomata, high humid atmosphere and well irrigated soil Closed stomata, dry atmosphere and dry soil Open stomata, dry atmosphere and moist soil3. In the mechanism of opening and closing of stomata, the important factor is The presence of Chloroplast in the guard cells The protein content of the cells The starch content of the cells The turgid and flaccid state of the guard cells4. 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 Photosynthesis occurs during day time only Loss of sugar increases osmotic concentration of the cell sap5. Most of the transpiration in tall trees occurs through Bark Stomata Lenticels Cuticle6. In hot summer days, plant cooling is due to Loss of water vapour from leaves Loss of water from entire plant Transport of water in plant Loss of liquid water7. Transpiration is very low during the storms due to None of the above High velocity of wind Low temperature during storms Presence of moisture in the wind8. With decrease in atmospheric pressure, the rate of transpiration will increase remains the same decrease slowly decrease rapidly9. Guttation is the elimination of excess of water from plants through Wounds Hydathodes Stomata Lenticels10. Plants lose water by guttation when Rate of transpiration is high Soil is wet and and the atmosphere is dry Soil is wet and and the atmosphere is humid Soil is dry and and the atmosphere is dry11 out of 10Please fill in the comment box below.
