write a difference between the tender coconut water and the thick, white kernel of a mature coconut and their ploidy.
Answers
Endosperm is formed when male gamete fuses with two polar nuclei.
Coconut water is part of endosperm of coconut and develops as post-fertilisation framework from primary endosperm nucleus.
In young coconut primary endosperm nucleus separates and forms large number of free nuclei without cell membrane giving a liquid shape.
Later stage when coconut matures in addition to free nuclei many cells enclosing variable number of nuclei is visible.
These cells separates fast and form compact mass of cells which start settling at end of cavity and layers of cellular endosperm start to be visible.
Mature coconut liquid endosperm becomes milky covered by cellular part called kernel but it doesn't has free nuclei/cells.
So, coconut water is free nuclear endosperm and white kernel is cellular endosperm.
Ploidy of both is triploid.
Coconuts are one of the most useful and beneficial natural ingredients that you will come across with.
The whole fruit can is used for different purposes.
The coconut water present inside the shell is an endosperm of free nuclear, but the white kernel present inside it is called the cellular endosperm.
When the coconut becomes matured, the coconut liquid endosperm turns milky which gets covered by the cellular part known as the kernel.
However, it does not consist of any free nuclei or cells.
