Answer:
A) Companion cells
Explanation:
Red blood cell is formed through a process called, erythropoiesis. During this process, the red blood cell loses the nucleus to increase its surface area for absorption. Vessel loses its nucleus while attaining maturity. Sieve tube cells lose the nucleus and many cell organelles at maturity. Therefore, they depend upon companion cells for their metabolic needs. Companion cells do not lose the nucleus at maturity. Therefore, option A is correct.
