Answer 1

Answer:

Explanation:

1.The Potometer does not measure the rate of transpiration accurately because not all of the water that is taken by the plant is used for transpiration (water taken might be used for photosynthesis or by the cells to maintain turgidity). The potometer measures the rate of uptake of water. To measure transpiration rate directly, rather than the rate of water uptake, utilize a scientific instrument which quantifies water transfer at the leaves.

i)The water retained by plant is so minute that it can be neglected.

ii)Introducing an air bubble may not be easy.

2.A twig may not be active for a long time.
