Question

In a fertilized ovule, the antipodal cells are__i__ zygote is diploid, and the endosperm is__ii__

The information in which alternatives completes the given statement?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Antipodal cells located at the chalazal end of the ovule are haploid. At the time of fertilization, the pollen tube contains two male gametes. One of these male gametes fuses with the egg cell and forms a diploid zygote while the other male gamete fuses with the polar nuclei located in the centre of the embryo sac to produce a triploid primary endosperm nucleus, which later on develops into endosperm. Hence, antipodal cells are haploid while endosperm is triploid.
