- Besides the presence of chloroplasts, another major difference between plant and animal cells is the presence of a cell wall. The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.

Apr 27, 2017 · All cells have cell membranes, but generally only plants, fungi, algae, most bacteria, and archaea have cells with cell walls. The cell wall provides strength and structural support to the cell, and can control to some extent what types and concentrations of molecules enter and leave the cell.
The plant cell wall is an elaborate extracellular matrix that encloses each cell in a plant. It was the thick cell walls of cork, visible in a primitive microscope, that in 1663 enabled Robert Hooke to distinguish and name cells for the first time.

Jul 21, 2017 · The cell wall prevents the plant cells from bursting and helps to give the plant the structural support it needs; the "turgor pressure" caused by osmosis helps to give the plant rigidity and keep it upright.
Oct 30, 2024 · Cell wall, specialized form of extracellular matrix that surrounds every cell of a plant. The cell wall distinguishes plant cells from animal cells and provides physical support and protection. Learn about the functions and chemical components of plant cell walls.
Jul 16, 2020 · Why do plant cells have a cell wall? Ans. The cell wall gives tensile strength and protection to the plant cell against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure exerted by the cell contents against their cell wall thus helping plants in their growth and development.
Feb 1, 2024 · We predict the next century of progress will include deciphering cell type–specific wall polymers; regulation at all levels of polymer production, crosslinks, and architecture; and how walls respond to developmental and environmental signals to drive plant success in diverse environments.
