Cell turgor is the pressure of the cell contents against the cell wall in plant cells, driven by water entering the cell via osmosis. It is crucial for maintaining cell rigidity, supporting plant structure, and driving growth processes such as cell elongation.

The cell wall is a rigid, protective layer found outside the cell membrane in plants, fungi, bacteria, and some protists, providing structural support and determining cell shape. Composed mainly of polysaccharides like cellulose in plants, it plays a crucial role in regulating growth, mediating cell-to-cell interactions, and protecting against mechanical stress and pathogens.

Plant cells are the fundamental building blocks of plant life, distinctively equipped with a rigid cell wall, central vacuole, and chloroplasts to carry out photosynthesis. These features enable them to store nutrients and convert sunlight into energy, ultimately supporting plant structure and growth.

Osmosis is the passive movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration, aiming to equalize solute concentrations on both sides of the membrane. This process is vital for maintaining cell turgor pressure and homeostasis in biological systems.

driving growth processes

Cell elongation is a crucial process in plant growth where cells increase in length, contributing to the overall growth and development of the plant. This process is regulated by various hormones, environmental factors, and genetic pathways that ensure proper cell wall loosening and expansion.
