Question

the movement of up steam of tall plants is least dependent on which of the following factor​

Answer 1

Answer:

The cohesion – tension theory of sap ascent explains how how water is pulled up from the roots to the top of the plant. Evaporation from mesophyll cells in the leaves produces a negative water potential gradient that causes water and minerals to move upwards from the roots through the xylem.

Answer 2

a) Guttation

• The Cohesion–Tension Theory of sap ascent explains how water is pulled up from the roots to the top portions of a plant or tree.
• Evaporation from mesophyll cells in the leaves, also known as Transpiration, produces a negative water potential gradient that causes water and minerals to move upwards from the roots through the xylem.
• Hence, (b) Transpiration, (c) Cohesiveness of Water Molecules, and (d) Tension within a column of water molecules are all essential to the movement of water upstream.
