Question

5.Write the main function of each:- a)Cell membrane b)Mitochondria c)Nucleus d)Ribosome e)Cytoplasm f)Golgi body g) Cell wall(in plant cell)

Answer 1

Hey friend!

The functions are as follows:

◆ Cell Membrane (a)

• Being selectively permeable, it permits only certain substances to pass through.

• It bounds the semi fluid content of the cells.

• It protects the inner contents and helps in maintaining the internal environment of the cell.

◆ Mitochondria (b)

Mitochondria provide energy for various metabolic functions of the cell. For these reasons mitochondria are called powerhouse of the cell.

◆ Nucleus (c)

• Nucleus I'd the control centre of the cell.

• It contains the hereditary material.

• It initiates and promotes cell division.

◆ Ribosomes (d)

Ribosomes help in protein synthesis.

◆ Cytoplasm (e)

Most of the chemical processes take place here, controlled by enzymes.

◆ Golgi body (f)

Golgi body is associated with the secretary activity of the cell.

◆ Cell wall (g)

• It provided a definite shape to the plant cell.

• It provided rigidity to the cell.

• It gives protection to the internal structures and plasma membrane of the plant cell.

Answer 2

Hey user,
here is your answer...
___________________________________
Write the main function of each:-

▶a) Cell Membrane➡

❇It controls the entry and exit of substances inside and outside the cell.

❇It acts as a boundary for the protoplasm.

▶b) Mitochondria➡

❇It is the powerhouse of the cell.

❇It generates energy for the entire cell in the form of ATP(Adenosine Triphosphate)

▶c) Nucleus➡

❇It is the brain of the cell.

❇It controls most of the activities that are occurred in the cell.

❇It also contains the hereditary material chromosomes.

▶d) Ribosome➡

❇It helps in protein synthesis.

▶e) Cytoplasm➡

❇It is a gel like material which contains vitamins, proteins, carbohydrates, minerals etc.

❇Here most of the cell activities takes place.

▶f) Golgi body➡

❇It stores all the materials in the cell.

▶g) Cell Wall➡
❇It is only found in plant cell.

❇It helps the cell to have protection against the variations in the environment.

❇It provides the cell with rigidity and definite shape.
