Cell is a structural and functional unit of living organ. Cell is also called the building block of life.
All living organs, plants and animals, microorganisms are consists with cell.
Cell are in two types
Prokaryotic cell
Eukaryotic cell
Except, virus from all types of bacteria, protozoa to higher types of Chordata all are consists with cell.
Structure of cell is very complex.
The two types of role of cell is consisting structure of living organ and regulating required function for alive.
One of the function of cell is producing energy to survive. Energy produces inside mitocondrae a necessary organalae of cell which is also said as a power house.
Reproduction is another function of cell controlled by two gametic cell.
Genetics and carry out the inheritance is another function of cell mediated by DNA that carries genetic code and found in neucleolous of nucleus.
Growing up of any living organ from smaller to bigger is mediated by cell division.
Metabolism is also mediated by cell. Absorbing glucose into ATP is a process of metabolism. On the other hand in plants photosynthesis is also occurred in plant leaf cell.
