Question

How the movement of sucrose into phloem takes place initially?

a. with the help of transpiration

b. with the help of water gradient

c. with the help of ATP molecules

d. with the help of ADP molecules​

Answer 1

Answer:

d. sucose come into the sieve tube cells through diffusion

Answer 2

Option C is the correct answer.

• The procedure of transport of food and mineral in plants is named translocation. When food like glucose or sucrose is transported to phloem tissue, utilising ATP, the concentration of water molecules reduces in that area this outcomes in the activity of water into the cells due to osmosis.
• The glucose equipped in the leaves is renovated into sugar. The sugar in the form of sucrose is shifted into the companion cells and then into the living phloem sieve tube cells by the active carrier. This builds a hypertonic situation in the phloem.

Hence, Option C is the correct answer.
