Answer:
Cells.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.
Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
<em><u>Factory worker = Cell organelle.</u></em>
1. Chief executive officer = Nucleus.
- The nucleus controls all the activities taking place in the cell and the synthesis of proteins.
2. Power house = Mitochondrion.
- The mitochondria provides all the energy required in the cell by transforming energy forms.
3. Maintenance team = Lysosomes.
- They are responsible for absorbing materials and breaking the materials taken in by the cells.
4. Functional managers = Chromosomes.
- They give sets of instructions for the synthesis of products.
5. Assembly line workers = Ribosomes.
- They are involved in the build up of proteins.
6. Assembly line = Endoplasmic Reticulum.
- This is where the ribosomes perform their tasks.
7. Security and support = Cytoskeleton.
- They help to maintain and support the shape of the cells.
8. Drivers or messengers = Vesicles.
- They ensure proteins are properly transported to the right and exact location.
9. Packaging unit = Golgi apparatus.
- Prepares the protein for export by chemically tagging them.
10. Gate man/procurement unit = Cell membrane.
- It is the wall of the cell and typically controls what leaves and enters the cell.
Hence, cells are living systems that have distinct structures and sets of functions.
