Plasma membrane is a selectively permeable membrane.Amoeba acquires its food through such processes. Such processes are known as endocytosis (endo → internal cyto → of a cell). The flexibility of the cell membrane also enables the cell to engulf in food and other material from its external environment.
The plasma membrane is flexible and is made up of organic molecules called lipids and proteins.Plasma membrane is the outermost covering of the cell that separates the contents of the cell from its external environment.It can be observed only through an electron microscope.Cell membrane is also called the plasma membrane.With the discovery of the electron microscope in 1940, it was possible to observe and understand the complex structure of the cell and its various organelles.Presented The cell theory, that all the plants and animals are composed of cells and that the cell is the basic unit of life. Discovered and coined the term cell in 1665
