Do plants make their own cell wall or is it already there ?

Plants, unlike other organisms, do not have a pre-existing cell wall. Instead, they actually create their own cell walls as they grow. The process of cell wall formation begins during cell division, when a new cell wall is built between the two daughter cells. This cell wall is made up of various components, such as cellulose, hemicellulose, and lignin.

Cellulose is the primary component of plant cell walls and provides strength and rigidity. It is synthesized by enzymes called cellulose synthases, which are embedded in the cell membrane. These enzymes produce long chains of cellulose that are then assembled into microfibrils, which form the structural framework of the cell wall.

Hemicellulose and lignin are also important components of the plant cell wall. Hemicellulose provides flexibility and allows the cell wall to expand as the cell grows, while lignin provides additional strength and resistance to degradation.

In summary, plants actively synthesize their own cell walls during cell division, using enzymes embedded in the cell membrane to create a complex scaffold of cellulose, hemicellulose, and lignin.
