Cell wall

The cell wall is the outermost covering of a cell, present only in plant cells. It is made up of pectin, hemicellulose, cellulose microfibrils, and proteins organized into two layers - primary cell wall and middle lamella. In many plant cells, a third layer called secondary cell wall, made up of lignin, is present between the primary cell wall and the cell membrane, and provides support, protection, and rigidity to plant cells.

Plant cells and animal cells have many in common. They both have essential organelles including a nucleus, mitochondria, cell membrane, ribosomes, endoplasmic reticulum (ER), Golgi apparatus, lysosomes, peroxisomes, and cytoskeleton. In addition to these common features, plant cells have three unique cellular structures or organelles that animal cells do not have – Cell wall, Vacuole, and Chloroplast.

Cellulose nanocrystals extracted from wood pulp are inexpensive as well as stronger than Kevlar or carbon fiber.

The cell membrane is a thin, semi-permeable barrier that surrounds and encloses the contents of a cell. It supports and helps maintain a cell's shape.

In the cell membrane labeled diagram, we see Glycolipid, Glycoprotein, Globular Protein, Carbohydrate, Cholesterol, Peripheral Protein, Alpha-Helix Protein, Channel Protein, and Integral Protein.
