Endosperm of gymnosperm is haploid(ploidy n), develop from
megaspore (n) before fertilization. ploidy of endosperm in angiosperm is 3n(central cell fused with one male gamete i.e 2n+n).

angiosperm - flowering plant fruit endosperm (3n) triploid gymnosperm - 'naked seed' trees cones endosperm (n) haploid
An example of a seed that has liquid endosperm would be a coconut. While it does contain cellular endosperm, the coconut milk would be considered liquid endosperm.
A Gymnosperm I think, How do you think I would know!!!!!!!! Gosh.!

No, triploid endosperm is in angiosperms only. Gymnosperm means "Naked Seed."
The aleurone layer is the outermost layer of the endosperm. Therefore it is also triploid and same as the ploidy of endosperm.
If the chromosome number of a plant is 16, then the ploidy level of the microspore mother cell would be 2n=16 (diploid) and the endosperm cells would typically be 3n=24 (triploid), as they result from the fusion of a haploid sperm cell and a diploid central cell in double fertilization.

The micropyle is a hole in the seed coat, it is literally nothing. Hence it is not made of cells and has no chromosomes.
The ploidy level of a seed coat is typically diploid, meaning it contains two sets of chromosomes. This allows the seed coat to develop and protect the seed embryo inside during germination and growth.
Generally, a somatic cell in a human body has 46 chromosomes, which are two complete sets of 23 chromosome pairs. Because they have two sets, these cells have a ploidy level of diploid.
