Question

Give about 5ponts of cell wall

Answer 1

Answer:

A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism. ... In bacteria, the cell wall is composed of peptidoglycan.

Answer 2

Answer :

Cell Wall :-

• Cell wall is the outer covering for the plasma membrane.
• It is only found in plant cells and fungi.
• It is rigid.
• Cell wall gives shape to the cell.
• It protects the cell from mechanical damage and infections.
• It helps in cell to cell interaction.
• It acts as a barrier for undesirable molecules (macro).
• Algae has cell wall which is made up of cellulose, galactans, mannans and minerals like calcium carbonate.
• Plant cell walls are made up of cellulose hemicellulose, pectins and proteins.
• The cell wall of young plant cell is termed as primary wall which is capable of growth.
• This cell wall gradually diminishes as the cell matures.
• Then, the secondary cell wall is formed towards the inner side of the cell.
• The middle lamella of cell wall is composed of calcium pectate.
• It helps in glueing different neighbouring cells together.
