Question

what helps in upword momvement water of xyelm vessels in small plants

Answer 1

Explanation:

The continuous evaporation of water(or transpiration) from the cells of a leaf crates a kind of suction which pulls up water through the xylemvessles. Thus, transpiration helps in the upward movement of water and dissolved minerals from the roots to the leaves through the stem.

Answer 2

Answer:

Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels (xylem). It is primarily generated by osmotic pressure in the cells of the roots and can be demonstrated by exudation of fluid when the stem is cut off just aboveground.Oct 13, 2020
