WebNov 16, 2024 · A photometer is a device which is used to measure the rate of water uptake by the plant. The water taken up by the plant is used in photosynthesis and transpiration. The usage of bubble in ganong’s photometer is to determine how much water has been taken up by the roots of the plants. Webü A reservoir constructed and equipped to provide storage and release of water for two or more purposes such as irrigation, flood control, power generation, navigation, pollution abatement, domestic and industrial water supply, fish culture, recreation, etc. ü It may be observed that some of these objectives may be incompatible in combination.
Potometers come in a variety of designs, but all follow the same basic principle. • A length of capillary tube. A bubble is introduced to the capillary; as water is taken up by the plant, the bubble moves. By marking regular gradations on the tube, it is possible to measure water uptake. • A reservoir. Typically a funnel with a tap; turning the tap on the reservoir resets the bubble. Some designs use a syringe instead. WebInformation about constructing the potometer The apparatus should be prepared by the technician in advance, to prevent accidents. It is crucial to avoid air bubbles in the assembled potometer. This is the most common reason for potometer failure. 1. Cut two 4mm holes and one 2mm hole in the bung (see safety note). 2.
Web(i) Ganong’s potometer(ii) A potometer does not measure the water loss by transpiration, but it measures the water uptake by the plant. Water absorbed by the plant is not completely lost by transpiration; some of the water is used for cell activities.(iii)Transpiration(iv)The part marked ‘Reservoir’ is used to bring the air bubble to its original position. This is done by … WebAll have some kind of reservoir or syringe which acts as a resetting mechanism by allowing little water into the capillary tube to clear the bubble so recording can begin. The plant shoot is held securely in a connected tube.
