What are Cells?
The building blocks of all living organisms are called Cells. Our body is made up of millions of such cells together. Thus, it is said to be life’s basic, structural, and functional unit.
Cells come in different numbers to form our body or any living organism’s body. Depending on
the number of cells present in the organisms, they are classified into two types:
- Unicellular Organisms – They are made up of only a single cell. For example, bacteria, protozoa, etc.
- Multicellular Organisms – They are made up of many cells.
For example, humans, dogs, etc.
All the cells in the body are not uniform and look very different.
