Lysosomes are the main digestive compartments of the cell. They lyse a cell. So it is called as scavengers of the cell.

Chromatin and nucleolus are the main things of nucleus.

It maintain the shape and protect the cell.

Plant and animal cells have a nucleus inside the cytoplasm. It is surrounded by a nuclear envelope. One or two nucleolus and the chromatin body are present inside the nucleus. During cell division the chromatin body is organised in a chromosome

Smooth ER and Rough ER

Cell wall and Cell membrane

Chloroplast and Mitochondria

(i) Golgi Complex:
Membrane bounded sacs are stacked on top of the other with associated secretory vesicles are collectively known as golgi complex. Functions of golgi complex are the production of secretory substances, packaging and secretion. This is the secret behind the change in the colour and taste of fruits.
(ii) Lysosome:
You will find organelles called as lysosomes, which are very small to view using a light microscope. They are the main digestive compartments of the cell. They lyse a cell, hence they are called "suicidal bag".
(iii) Nucleus:
Plant and animal cells have a nucleus inside the cytoplasm. It is surrounded by a nuclear envelope. One or two nucleolus and the chromatin body are present inside the nucleus. During cell division, the chromatin body is organised into a chromosome. Storage of genetic material and transfers heredity characters from generation to generation are the functions of chromosome.

Virus is called Acellular because they are not built up out of cells. They are much smaller than cells.
They reproduce only in the living host cells. So virus is called Acellular organisam.
