The structural and fundamental unit of living beings is called a cell.
The cell is grouped into organs and tissues.
There are many different types of cells that perform specific functions.
Functions of all cells:
The major functions of all cells are as follows:
Synthesis of proteins: These proteins are synthesized in the ribosomes borne on the rough endoplasmic reticulum and are crucial for all cellular activities. This is the primary function of all cells.
Generating energy: Cells require energy to carry out various chemical processes. This energy is produced by the cells through a process called photosynthesis in plants and respiration in animals.
Transportation of molecules: The cell membrane is laden with transport proteins that allow the influx and efflux of important molecules.
Reproduction: A cell aids in reproduction through the processes called mitosis and meiosis. Mitosis is termed as asexual reproduction where the parent cell divides to form daughter cells. Meiosis causes the daughter cells to be genetically different from the parent cells.
