How many chromosomes are in a Gymnospermic endosperm?

How do you find the number of chromosomes in endosperm?

Endosperm is triploid (3n) = 27. Hence, n = 9. Definitive nucleus, i.e. the secondary nucleus is diploid, i.e. 2n. Therefore, the number of chromosomes is 18.

What is the chromosome set of an endosperm?

Each nucleus within the pollen tube contains one haploid set of chromosomes. The egg also contains a haploid set of chromosomes, while the zygote is diploid (with 2 sets of chromosomes) and the endosperm is triploid (with 3 sets of chromosomes).

The endosperm is a structure that provides nutrition to the developing embryo inside the seed. The endosperm of gymnosperms is haploid as it is produced by the female gametophyte before fertilization takes place.

What will be the number of chromosomes in primary endosperm cell?

So primary endosperm cell has the 6 chromosomes in nucleus. Each haploid nucleus of embryo sac contains the 4 chromosomes. But if 2n=8 then the endosperm contains the 12 number of chromosomes.
