Hint: We all are well versed with the fact that cells are the structural and functional unit of all living organisms. Every individual is made up of cells, either one or many. Each and every vital function that we perform is due to the cells. There are various organelles of a cell which have different duties to fulfill. The hereditary material is contained in the cell.
Complete answer:
- Human body is made up of trillions of cells. They are very tiny but they are very important for our body. Without cells there is no life.
- The reason for them being so tiny is because they have to maintain surface area to volume ratio which is very essential for intake of the nutrients as well as to excrete wastes. Therefore being small is an advantage because they get a large surface area.
- Cells are composed of proteins and organelles. Cells have remarkable organizing power. They can efficiently move through our body similar to the blood cells.
- Apart from all these, cells perform some very important functions. They provide a proper structure and support to our body. For example, the skin is made up of many skin cells that give a proper structure.
- They are also important where mitosis is concerned because the tissues grow when cells multiply. Our body performs many chemical reactions daily by the cells which require a huge amount of energy. Animals get this energy through respiration.
- Cells aid in the reproductive processes also by the mitosis process where asexual reproduction is involved and in meiosis where sexual reproduction is concerned.
Note: The longest cell in the human body are the motor neurons and they can extend up to 4 to 5 feet. The largest cell is the egg cell in the female body but it is very small to be seen with naked eyes. Each and every cell has specialized functions. For instance, the muscular cells of the heart organize and make up muscle tissue of the heart walls.
