- A plant cell is distinguished from the cells of other organisms by its cell wall, chloroplasts, and central large vacuole.
- The cell wall and central vacuole work together to give the cell rigidity.
- The plant cell wall is mainly made of cellulose(the most abundant macromolecule present on Earth).
- Besides cellulose, hemicellulose, pectin, lignin, and proteins are other components of the plant cell wall.
- A plant cell wall is arranged in three major layers: primary cell wall, middle lamella, and secondary cell wall.
