Question

Give any two examples of each endospermic (albuminous) seeds and non-endospermic seeds

Answer 1

Hint: Plants that contain seeds with endosperm even after maturity seen in monocots and in some plants like the plants in the Leguminosae family, the endosperm is absent as the developing embryo consumes all the embryo

Complete answer:
If the endosperm is completely consumed by the developing embryo before the maturation, such seeds are described as non-endospermic seeds. They are also called non-albuminous seeds.

If the endosperm is not completely consumed by the developing embryo and that endosperm is present after the maturation, such seeds are described as endospermic seed or albuminous seeds
Examples of non-endospermic seeds are pea, groundnut, and beans
Examples of endospermic seeds are castor, Maize, and coconut

Additional information:
- After the fusion of three cells called triple fusion the central cell present in the embryo sac becomes the primary endosperm cell (PEC) and later it gets developed into the endosperm.
- This endosperm cell divides repeatedly and forms a triploid endosperm tissue that contains reserved food material.
- This food is used as an energy source by the developing embryo
- The most common type of endosperm development is the formation of free nuclei by the successive nuclear divisions of the primary endosperm nucleus.
- If the endosperm is completely consumed by the developing embryo before maturation then the formed seeds are called non-endospermic seeds and if the endosperm persists even after the maturation such seeds are called endospermic seeds.
- Development of endosperm is the post-fertilization event that occurs in most of the higher plants such as gymnosperms

Note: The water inside the coconut is free nuclear endosperm and the white kernel is cellar endosperm
The scientific names of coconut, castor, ground nun, peas, and beans are cocculus indicus, Gossypium herbarium, Arachis hypogea, Pisum sativum, and Phaseolus vulgaris respectively.
