Question

How will you explain that cell exhibit the division of labour

Answer 1

Organelles(present within a cell) are small and function analogous to organs in a large organism. Organelles play a huge role in the production of cellular energy, control of cellular activities, etc.

For the cell survival and functionality, each of the cell organelle perform a very specific role. This is called the Division of Labour.

Here are some of the cell organelles and their functions:-

Cell membrane- It surrounds the cell and acts as a barrier between the external environment and the cell. It is also a semi- permeable membrane( selectively allows materials to go in and out of the cell).
Nucleus- "Brain of the cell." It controls and regulates all the activities of the cell. It is bound by a double membrane called the nuclear envelope.Chromosomes are located within the nucleus. Chromosomes consists of DNA, which contains the heredity information and contributes for cell growth, development, and reproduction. Nucleus also has a dense region called nucleolus which consists of RNA and proteins.
Cytoplasm- This is a gel- like substance that is present in the cell. All the organelles are located within the cytoplasm. It supports the cell and also have materials like nucleic acid, chemicals, etc within it.
Mitochondria- "Power house of the cell." These organelles generate most of the energy of the cell in the form of adenosine triphosphate (ATP) and it is used a source of chemical energy. The mitochondria also is involved in cellular activities like signaling, cellular differentiation, cell senescence and also in the control of cell cycle and cell growth.
Golgi apparatus/body- Golgi Bodies are structures that take the form of stacks of membranes and function to pack and modify proteins for exportation outside of the cell.
Lysosomes-Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids.
Centrosomes and Centrioles-A centrosome is an organelle that is found close to the nucleus within the cytoplasm of cells. Centrosomes are key to the division of cells and produce the spindle fibers that are required during metaphase of mitosis. Each centrosome consists of two centrioles that are orientated at right-angles to each other.
Ribosomes-They contribute to the protein synthesis. The can either be found in the cytoplasm or attached to the endoplasmic recticulum.
Endoplasmic recticulum
Smooth ER- Devoid of ribosomes. They are concerned mostly with lipid synthesis.
Rough ER-Has ribosomes attached to them. Hence, they play a role in protein synthesis, assembly and dispatch.
I might have missed out on an organelle or two. But these are some of the very fundamental organelles. To answer your question about division of labour, all the cell organelles within the cell work together by performing different tasks for the cell functionality , survival, differentiation.
