Concept explainers
To discuss:
The selective permeability of plasma membrane and its importance in survival of humans.
Introduction:
Cells are regarded as the simplest unit (structural and functional) of life. Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Cellular membrane, which surrounds the entire cell, is composed of phospholipids and proteins. The nucleus is bound by a nuclear membrane, and it possesses the genetic material of the cell. Cytoplasm consists of organelles, cytoskeleton (filaments and tubules), and inclusion bodies. Protoplasm denotes all living material that are present in the cell enclosed by the cellular membrane (inside and outside the nucleus).
