Question

the osmotic pressure in pholem increases on transfer of ______ into it from the leaves​

Answer 1

Explanation:

food.pholem for food conduction. xylem for water

Answer 2

Answer:

• Water entered the phloem through the process of osmosis from the neighboring xylem, much as sugar is transferred from the leaves into the phloem by active transportation. This causes the osmotic pressure of the phloem to rise.

• The same leaf vein receives water through osmosis from the neighboring xylem. This raises the sieve tube elements' hydrostatic pressure.
• Finally, there is still some reasonably pure water in the phloem, which is considered to either depart by osmosis or be drawn back into adjoining xylem vessels by the transpiration pull.
• The amount of pressure required to stop water from entering a solution through a semipermeable membrane is known as osmotic pressure. It can also be described as the lowest pressure required to cancel out osmosis.
