Question

Which components of phloem tissue work together to transport photosynthetic products to different parts of the plant body?

Select one of the options below as your answer:
A. Sieve elements and companion cells
B. Mesophyll cells and stomata
C. Tracheids and vessels

Answer 1

The correct option is A.

Step-by-step explanation:

Phloem is the conductive tissue responsible for the transport of organic nutrients, produced by photosynthesis. It is composed of two types of conductive cells: sieve tubes and companion cells, the first are responsible for sieve the structures, at the ends of the sieve tube elements, pores are formed, these small pores allow dissolved nutrients to travel through of the tube. On the other hand, the companion cells have nucleus and ribosomes and feed the sieve elements, these cells are responsible for maintaining and controlling these elements metabolically.

Answer 2

Sieve elements and companion cells of phloem tissue work together to transport photosynthetic products to different parts of the plant body.
