Answer:
Cytoplasm is a liquid present between the cell membrane and the nucleus. It contains all the cell orgenelles of the cell.

Question :-
What is cytoplasm? Explain it briefly.
Answer :-
The jelly-like substance present between the cell membrane and the nucleus is called cytoplasm .There are various other components present in the cytoplasm. They are called the cell organelles .
Some of the cell organelles are mentioned below :-
Mitochondria :-
They are called the powerhouse of the cell because they act as the source of energy production. They are the organelles that act like the digestive system of the cells because they take in the nutrients, break them down and produce energy for the cell. The process of creating cell energy is known as cellular respiration.
Mitochondria are very small, spherical and rod-shaped . The number of mitochondria in a cell depends on what the cell needs to do. For example, a cell like the muscle cells, which needs more energy to perform its activities, has more number of mitochondria. Both the plant and animal cell process mitochondria.
Golgi bodies :-
They are responsible for the secretion of chemical substances like enzymes, hormones and proteins. Hence, they are called the post office of the cell. They are made up of vesicles (small vessels), tubules (long tube-like structures) and vacuoles (empty spaces). They are present in both plant and animal cells.
Ribosomes :-
They are the small granular structures scattered in the cytoplasm. They are the protein builder's or the protein synthesisers of the cell, therefore, they are called the factories of the cells.
Centrosome :-
It is located in the cytoplasm, usually close to the nucleus. It initiates and regulate cell division. This structure is present only in animal cells.
Plastids :-
Plastids are the largest of all the cell organelles but they are present only in plant cells.
There are three types of plastids found in plant cells. They are - chloroplasts, chromoplasts and leucoplasts.
Lysosomes :-
They small spherical sac- like structure present in the cytoplasm of animal cell. They hold the digestive enzymes that are created by the sale and thus help in digestion. When the cells absorb food lysosomes attached to it release their digestive enzyme.
Endoplasmic reticulum (ER) :-
This complex organelles help in the synthesis, storage and transportation of materials within the cells. Both plant and animal cells have endoplasmic reticulum.
Vacuoles :-
Vacuoles are single-layered membrane bounded by sac-like vesicles present in the cytoplasm. A plant cell has a larger vacuole compared to an animal cell. Vacuoles store excess water, useful mineral, pigments and many other substances.
