the process by which is drawn up through the stems and lost through leaves is called?

Question

a-root pressure
B-evaporation
C-osmosis
D-adhesion of water molecules
E-cohesion of water molecules

Answer 1

The process of losing water through the leaves is transpiration. It occurs because water molecules stick to themselves called cohesion. E

Answer 2

Plants secure the water they need from their roots.

The path taken is: soil -> roots -> stems -> leaves

Less than 1% of the water reaching the leaves is used in photosynthesis and plant growth.

Most of it is lost from the leaves by transpiration.
The mechanism suggested for this is that the loss of water in the leaves exerts a pull on the water in the xylem ducts draws more water into the leaf.

This is possible because of the cohesion of water molecules; i.e. the property of water molecules to cling to each through the hydrogen bonds they form.

Thus the cohesion of water molecules is a phenomenon that aids in the pull of water, but it is not the name of the process.

Root pressure plays a role in the transport of water in the xylem in some plants and in some seasons, but it does not account for water transport.

Answer 3

E. is the answer, but the chioce could have been better written as "transpiration-pull, cohesion tension"

Answer 4

Cohesian-E

Answer 5

photosynthesis?
