What Is The Main Function Of The Wall Of A Cell In Plant Cells? Find Out The Answer Here

YOGYAKARTA Every part of plant cells plays an important role in the survival of plants, including cell walls. So, what is the function of cell walls in plant cells?

Please note, the walls of cells are the outermost part of plant cells. This part is composed of cellulose, lignin, and suberin. This component makes the walls of cells sturdy but still flexible.

while in certain parts such as leaf epidermis and stems, cell walls can contain kitin and waxy substances that are impermeble or cannot be penetrated by water.

As the outermost part of plant cells, the walls of the cells are like a protective bastion. The main function of the walls of cells on plant cells is to maintain and protect the cells in them.

In addition to protecting cells, there are several other functions of cell walls on plant cells, including:

Referring to the book Biological for Class XI Semester 1 SMA by Oman Karmana (2008), the cell wall consists of three main layers, namely primary cell walls, secondary cell walls, and tertiary cell walls.

The following is the explanation of each part of the cell wall on plant cells:

This layer is found in young cells that are still actively dividing (embrionic) or on the parenkim network. The walls of primary cells are flexible so that cells can grow and develop.

This layer forms after the walls of the primary cells, leading to the inside of the cells. The walls of secondary cells have a stronger and thicker structure because they contain cellulose microfibriles and lignine fibers, thus functioning to strengthen cells and maintain their shape.

It is the deepest layer that borders the plasma membrane directly. Even though it is thin, this layer completes the overall cell defense structure.

In addition to the three layers, there is a middle lamela, which is a layer of inter-cell adhesive that brings together the plant tissue. The Lamela is composed of pektin substances and is located on the outermost part of the cell wall.

With complex structures and diverse functions, cell walls are one of the important elements that ensures plants can grow, stand tall, and survive various environmental conditions.
