draw the cabled digram of plant cell and animal cell and write the different? between cell wall and cell membrane
Answers
Explanation:
The cell wall is the outermost covering of plant cells. It is present outside the cell membrane and is tough, flexible and sometimes rigid in its texture. It is mainly composed of cellulose, long fibres of carbohydrates including hemicellulose, lignin and pectin.
The main functions of the cell wall are:
Protecting the cell against physical damage and invading pathogens.
Regulates and controls the direction of cell growth.
Providing the strength, structural support and maintaining the shape of the cell.
Functions as a storage unit by storing carbohydrates for use in plant growth, especially in seeds.
It allows entry of smaller molecules through it freely.

Cell Membrane is present in all organisms including plants
The cell membrane is also known as the plasma membrane. It is the outermost covering of animal cells. It is a semi-permeable membrane composed of lipids and proteins. The main functions of the cell membrane include:
Protecting the integrity of the interior cell.
Providing support and maintaining the shape of the cell.
Helps in regulating cell growth through the balance of endocytosis and exocytosis.
The cell membrane also plays an important role in cell signalling and communication.
It acts as a selectively permeable membrane by allowing the entry of only selected substances into the cell.
