Question

With respect to angiosperms, identify the correct option.

• A. Antipodals – n
• B. Vegetative cell of male gametophyte –2n
• C. Primary endosperm nucleus – n
• D. Cells of nucellus of ovule – n

Answer 1

The correct option is A Antipodals – n

Antipodal cells are three haploid cells which are located at the chalazal end of the embryo sac. Hence their ploidy is n.

Vegetative cell of pollen grain (male gametophyte) is haploid. Hence the ploidy is n.

The ploidy of primary endosperm nucleus (PEN) is 3n.

Cells of nucellus of ovule are diploid- 2n.
