b) providing water to phloem
c) loading of sucrose into sieve element by passive transport
d) loading of sucrose into sieve element​

Answer 1

Answer: d is correct answer.

Pls mark me brainliest

Answer 2

Answer:

Explanation:

d       Sucrose is loaded (moved into companion cells) by active transport, against the concentration gradient. ... The sucrose can then diffuse down the concentration gradient into the sieve tube element via the plasmodesmata that connects the companion cell with the sieve tube element.
