Question

In case of polyembryony ,an embryo A develops from the synergids and the embryo B develops from the nucellus . state the ploidy of embryo A and B?

Answer 1

In the case of polyembryony, when an embryo A develops from the Synergids and the embryo B develops from the nucellus, then A is Haploid and B is Diploid.

Haploid is the condition when the cell contains half the number of usual chromosomes.

Diploid is the usual chromosome number of the somatic cells of an organism.

Answer 2

The presence of more than one embryo in a seed is called polyembryony, e.g. lemon, groundnut, etc.

Polyembryony plays a main role in plant breeding and horticulture.

It has been considered by synergids and could carry out by following the polyembryony and develops from the nucellus which should guide in developing from synergid.
