GENERAL HISTOLOGY

Detailed explanation-1: -Plasma membrane is the outermost protective layer in cells of all plants and animals.

Detailed explanation-2: -The outer lining of a eukaryotic cell is called the plasma membrane. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules.

Detailed explanation-3: -Glycolipids are found on the outer part of the cell membrane. Phosphoplipid bilayers now make up the plasma cell membranes that regulate movement into and out of prokaryotic and eukaryotic cells. It is thought that early membranes may have been made of simpler fatty acids.

Detailed explanation-4: -The epidermis is the protective outer layer of clonally related cells covering all plant organs.
