Is the main pressure of the cells contents against the cell wall in plant cell?

Yes, in plant cells, the main pressure of the cell's contents is exerted against the cell wall, a phenomenon known as turgor pressure. This pressure results from the osmotic movement of water into the cell, which fills the central vacuole and pushes the cell membrane against the rigid cell wall. This turgor pressure is crucial for maintaining cell shape, supporting the plant structure, and facilitating growth.
