Question

Suggest why the rate of water movement in an intact shoot is less than that measured in a leafy shoot cut from plant.

Answer 1

because of transpiration. Transpiration happens because of the existence of leaf, and why is that? because leaf has stomata through which water in the form of vapor state diffuses out into the open air and when this happens there are less water potential at the top compare to the bottom and this cause a difference in the water pressure and this difference causes water moment. All this happens because of the leaves and if there is no leaves, there is almost no water difference hence no water movement in a leafless shoot

Answer 2

if you have further question feel free to ask

Answer 3

Okay, all that makes sense but the question is more along the lines of "why is the rate of movement faster in the piece of the plant (with leaves) in the potometer Greater than the rate of movement of the same plant when it was still intact (with leaves)?"

Answer 4

But thanks for the effort you've put in!
