Question

What are cell inclusions

Answer 1

Cytoplasmic inclusion. ... Inclusions are stored nutrients, secretory products, and pigment granules. Examples of inclusions are glycogen granules in the liver and muscle cells, lipid droplets in fat cells, pigment granules in certain cells of skin and hair, water-containing vacuoles, and crystals of various types.

Answer 2

$\huge\mathfrak\pink{Answer}$

★ Cell inclusions

Cell inclusions are considered various nutrients or pigments that can be found within the cell, but do not have activity like other organelles. Examples of cell inclusions are glycogen, lipids, and pigments such as melanin, lipofuscin, and hemosiderin.

‎ ‎‎ ‎There are non - living structures of the ‎cytoplasm . These include :

★ Reserve food :-

It is present either in the form of grains. ( e.g. Starch grains of potato Tuber cells) or granules ( e.g. of glycogen in liver and muscle cells) ; or droplets ( eg. Oil droplets in fat cells).

★ Vacuoles :-

These are absent from the prokaryotes. These are, small size but many in number in animal cells while plant cells have single and large central vacuoles ( while occupies 50 - 90 % of the cell volume), so the nucleus and cell organelles are pushed near the cell wall.

‎ ‎ ‎ ‎ ‎ ‎ ‎ A vacuole is formed of outer limiting membrane, called tonoplast, and a liquid inside called cell sap.

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ Cell sap exerts an outward trugor pressure while vacuoles act as storage sacs of water, minerals toxic metabolitics etc.
