What is a cell?

A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.

Function of cell :

Cells provide six main functions. They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.

Parts of cells :

It include- cell wall, cell membrane, cytoplasm, nucleus, chromosome , mitochondria , ribosomes and cell organelles.

1. Cell membrane :

Every cell has a thin outer covering called the cell membrane, or plasma membrane. The cell membrane surrounds the contents of the cell and separates it from other cells and the environment. The cell membrane also controls what materials go into and out of the cell.

2. Cytoplasm :

The cytoplasm and specialized working parts called organelles are inside the cell membrane. The cytoplasm is a sea-like fluid that contains water and other chemicals. Some of these chemicals are found throughout the cytoplasm.

3. Nucleus :

The nucleus is the most important part of a cell. It is the “information” headquarters and is in charge of the cellular activities. It contains the information that will tell the cell what to do, what to make, and when to divide. A nucleus is a small and very powerful part of a cell.

4. Chromosomes :

If you looked at one of your cells under a microscope, you would see that under certain conditions, structures called chromosomes appear in the nucleus of the cell.

5. Mitochondria :

Cells require a continuous supply of energy. Mitochondria have the job of converting energy in the food you eat to a form that is usable by cells. Mitochondria are fairly large organelles.

6. Ribosomes

Proteins are important molecules produced by cells. Ribosomes are the organelles where proteins are produced or synthesized. Ribosomes are themselves made up of proteins.
