GENERAL HISTOLOGY

Detailed explanation-1: -The outermost layer found in a plant cell is a cell wall made up of cellulose and lignin that acts as a protective covering and provides mechanical strength to the cell. Plant cells have a cell wall as well as a cell membrane whereas animal cells have only a cell membrane.

Detailed explanation-2: -The epidermis is the protective outer layer of clonally related cells covering all plant organs. It is composed of a number of specialised cell types which differentiate from the basal epidermal cell in adaptively significant frequencies and patterns.

Detailed explanation-3: -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-4: -The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
