Question

In angiosperm reproduction the fertilization of the two synergids gives rise to endosperm.

This sentence make no sense

This is a true statment, but only for angiosperms.

This sentence is almost true, it is the antipodals that are fertilized, not the synergids

This sentence is true, but only for gymnosperms.

Answer 1

Ans: The correct option is A (It makes no sense)

In angiosperms, an unfertilized ovule has 8 cells (1 egg cell, 2 polar central cells, 3 antipodal cells, and 2 synergids). The pollen tube releases 2 sperm in the ovule. 1 sperm fertilizes the egg cell to form a diploid zygote and another sperm fertilizes central cell. The large cell of gametophyte develops into the endosperm.

The role of synergid is to attract pollen tubes into megagametophyte. Antipodal cells function to provide nutrition to embryo sac.
