Question

Coconut water from a tender coconut is
(A) Degenerated nucellus
(B) Immature embryo
(C) Free nuclear endosperm
(D) Innermost layers of seed out

Answer 1

Hint: The coconut at its initial development stage is called the tender coconut. In the tender coconut, the inside cavity of the kernel is fully filled with the water. Later on, it gets developed into the hard coconut. This tender coconut is very healthy and provides the immediate energy.

Complete answer:
In the coconut there is the coconut water and it is surrounded by the kernel. This water represents the nuclear endosperm that is free floating and the kernel indicates the cellular endosperm. The primary endosperm nucleus (PEN) first goes through various free cell divisions without the formation of the wall in order to form a large free nucleus. This is the free nuclear endosperm.

At the point when the coconut fruit is small, the undeveloped embryo sac gets loaded up with a clear liquid in which the various free nuclei float in it. At a later stage of the development of the fruit, when it comes to a bigger size, the suspension shows, many cells are formed around the nucleus, a few cells each encasing a variable number of cores. Bit by bit these newly formed cells and free-floating nuclei all begin to settle at the fringe of the cavity, and layers of hard cell endosperm begin showing up with the increasing thickness. This forms the structures of the coconut meat. The amount of the cell endosperm increments further by divisions of the cells in the cell endosperm.

Hence the correct answer is OPTION(C)

Note: After the maturation of the coconut from the tender coconut, the white meat of the coconut is called as the nucleus and the brown hard layer covering the white meat is the endosperm. The fibers surrounding that is mesocarp.
