Which is a funtion of the cell structure that id labeled x?

a. it stores lipids.
b. it cell metabolism.
c. it provides support.
d. it transports proteins.

The correct answer will be option C (it provides support).

Explanation:

In-plant cells, the structural support to the cell is provided by a rigid layer called "cell wall" which is formed outside the cell membrane.

The cell wall is made up of cellulose molecule and is present in two types in plant cells: primary wall and secondary walls.

the primary wall surround the growing cells or elastic cells whereas secondary wall surrounds the specialized cells such as fibre cells of vessel elements due to the deposition of lignin providing rigidity to the cell.

Thus, option C (it provides support) is the correct answer.

i think the answer is b.
