Solution
Cell is the smallest structural and functional unit of all living organisms and is a membrane bound structure enclosing the protoplasm.
The two types of cells are:
- Prokaryotic cells – These cells lack a well-organised nucleus and membrane bound organelles. They are usually found in unicellular organisms, which are referred to as prokaryotes. Examples of prokaryotes are bacteria and blue-green algae.
- Eukaryotic cells – These cells possess a well-organised nucleus and membrane bound organelles. Organisms made up of eukaryotic cells are called eukaryotes. Examples of eukaryotes are plants and animals.
