The Cell

Presentations | English

In biology, cell is considered as the basic unit of a living organism. Some organisms are complete with single cell like a bacterium or yeast. It is a unit that is bound with fundamental molecules of life which perform specific activities. Cells can be prokaryotic or eukaryotic, which can be differentiated on the basis of a well defined nucleus surrounded by a nuclear membrane in eukaryotes. In eukaryotes, apart from nucleus, there is organelles like mitochondria, plastids, endoplasmic reticulum and Golgi apparatus. Nucleus is the largest organelle with DNA or genetic material in it. Mitochondria is the powerhouse of eukaryotic cells, because it supplies energy by generating adenosine triphosphate through cellular respiration. Endoplasmic reticulum carries out lipid synthesis, carbohydrate metabolism, drug detoxification which are interconnected network of flattened sacs. Cell cycle is the process by which a cell undergoes growth and division. More information about this topic is available in the powerpoint presentation.
