उत्तर
- The building blocks of all living things are cells. The structural unit of life is therefore the cell.
- Because of the particular arrangement of its membrane and cytoplasmic organelles, every cell has its own unique structure and function.
- Cells with this kind of organization are able to carry out essential processes like breathing, getting nutrients, getting rid of waste, making new proteins, etc. Thus, the fundamental functioning unit of living things is the cell.
