The plant cell has a cell wall, but animal cells do not; this is because the cell wall is responsible for giving plant cells their cuboid forms and the capacity to grow taller and wider, which allows plant cells to absorb more sunlight and produce their own nourishment.
In plant cells, the plasma membrane is surrounded by the cell wall, which not only provides tensile strength but also shields the plasma membrane from mechanical and osmotic stress. In addition to this, it makes it possible for cells to create turgor pressure, which refers to the pressure exerted by the contents of the cell against the cell wall.
What is the cell wall?
The Function of the Plant Cell Wall This micrograph depicts the inside of a plant cell, revealing its many organelles. The nucleus is the conspicuous, spherical organelle that is accompanied by the tiny red nucleolus. The cell wall may be seen as the thin layer that is present between the cells.
