2. What is the structure of cells?

============

 

1. Like buildings are made with bricks, our body is also made up of cells; we can say that they are building blocks of our body.

 

2. Some organisms are made up of only one cell; they are called single celled organisms. You can read our ‘Animal World’ series to know more about these.

 

3. But some organisms are complex and have a lot of cells in them, so let us know more about cell and let’s know its structure.

 

4. So let’s start with the cell membrane; each cell is enclosed with a thin boundary which is called cell membrane.

 

5. Then we have the nucleus. In each cell there is a distinct, centrally located spherical shape nucleus. The nucleus is surrounded with a jelly-like substance called cytoplasm.
