How is the endosperm is derived?

In seeds of flowering plants, the embryo is surrounded by a nutritive tissue called endosperm. Embryo and endosperm are derived from individual fertilization events (double fertilization) and develop embedded in maternal tissues that form the seed coat.

Hereof, what is the purpose of the endosperm?

Endosperm. The endosperm is the tissue produced inside the seeds of most of the flowering plants following fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. This can make endosperm a source of nutrition in the human diet.

Why is the endosperm triploid?

The endosperm of the flowering plant mediates the supply of maternal resources for embryogenesis. An endosperm formed in sexual reproduction between diploid parents is typically triploid, with a 2 : 1 ratio of maternal genetic material (denoted as 2m : 1p).

What is the ploidy of the endosperm in the Gymnosperm?

The ploidy level of endosperm of gymnosperm is haploid i.e 1n. The endosperm in gymnosperms is haploid because it is formed from the haploid megaspore by repeated divisions. This endosperm consequently develops into female gametophyte with haploid chromosomes.
