Concept explainers
To define:
The term endosperm.
Introduction:
In
To determine:
Endosperm derived from which cell of the female gametophyte.
Introduction:
Endosperm is developed from the triploid nucleus of a flowering plant. It acts as a food storage part of the seed which provides nutrients to the developing embryo.
To compare:
The storage site of endosperm in
Introduction:
Endosperm is produced by the fusion of sperm cell which contains one nucleus with the large central cell which contains two nuclei. The fusion of single nucleus sperm cell with large central cell results in the development of endosperm.
