Question

The central cell after triple fusion becomes the

• A. PEC and develops into embryo
• B. PEN (primary endosperm nucleus)
• C. Diploid
• D. PEC (primary endosperm cell)

Answer 1

The correct option is D PEC (primary endosperm cell)

Formation of PEC
Triple fusion refers to the fusion of one of the haploid male gametes, released by the pollen tube into the embryo sac, with the diploid central cell of the embryo sac. This results in the formation of a primary endosperm cell (PEC) that contains the triploid primary endosperm nucleus (PEN).
The PEC develops into the endosperm which is a nutritive tissue that nourishes the growing embryo.

Porogamy

In porogamy, the pollen tube enters the ovule through the micropylar opening. This is the most common route of entry for the pollen tube in most plants

Final answer
(A) PEC (primary endosperm cell)
