Question

The endosperm of the angiosperm seed is a direct result of:

having sporophytes with both microsporangia and megasporangia

having both staminate and carpellate flowers

the gametophyte being physically and physiologically dependent on the sporophyte

maturation of the ovary

double fertilization

double fertilization

Explanation / Answer

The correct option is double fertilization.

The endosperm of the angiosperm seed is a direct result of the process of double fertilization. Endosperm is formed when the two sperm nuclei inside a pollen grain reach the interior of a female gametophyte.

Both a diploid embryo and triploid endosperm is the result of double fertilization in angiosperms.
