Sieve tube cells are closely related to the companion cells via the plasmodesmata. At the start, they possess a nucleus, however, at the prime stage they lose the ribosomes, nucleus, and vacuoles and get segregated for the conduction of food. The nuclei of the companion cells monitor the activities of the sieve tube cells via plasmodesmata. Hence, even the mature sieve tubes are enucleated, they remain living.
