Cell Biology

Cell Biology:
Cells consist of cytoplasm enclosed within a membrane, which also contains many biomolecules such as proteins and nucleic acid. The number of cells in plants and animals varies from species to species, it has been estimated that humans contain somewhere around 40 trillion (4×1013) cells. Enclosing the cell is that the cell envelope – generally consisting of a cell membrane covered by a cell wall which, for a few bacteria, could also be further covered by a third layer called a capsule.
