● Following double fertilisation, events of endosperm and embryo `color{Violet}"development"`, `color{Violet}"maturation"` of ovule(s) into seed(s) and ovary into fruit, are collectively termed `color{Violet}"Post-fertilisation events"`.
`color{Brown}"ENDOSPERM"`
● Endosperm development `color{Violet}"precedes"` `color{Violet}"embryo"` development.
● The primary endosperm cell `color{Violet}"divides repeatedly"` and forms a `color{Violet}"triploid endosperm tissue"`.
● The cells of this tissue are filled with `color{Violet}"reserve food materials"` and are used for the `color{Violet}"nutrition"` of the developing embryo.
● In the most `color{Violet}"common type"` of endosperm development, the PEN undergoes `color{Violet}"successive nuclear divisions"` to give rise to `color{Violet}"free nuclei"`.
● This stage of endosperm development is called `color{Violet}"free-nuclear endosperm"`.
● Subsequently `color{Violet}"cell wal"`l formation occurs and the endosperm becomes `color{Violet}"cellular"`.
● The `color{Violet}"number"` of free nuclei formed `color{Violet}"before cellularisation"` varies greatly.
● The `color{Violet}"coconut water"` from tender coconut that you are familiar with, is nothing but `color{Violet}"free-nuclear endosperm"` (made up of thousands of nuclei) and the surrounding `color{Violet}"white kernel"` is the `color{Violet}"cellular endosperm"`.
● Endosperm may either be `color{Violet}"completely consumed"` by the developing embryo (e.g., pea, groundnut, beans) before seed maturation or it may `color{Violet}"persist"` in the mature seed (e.g. castor and coconut) and be `color{Violet}"used up"` during seed germination.
