The cell wall of plants maintains the shape of plant cells, supports and strengthens plants, resists water pressure, controls cell growth, regulates metabolic processes for the plant, acts as a physical barrier for the plant, stores carbohydrates and helps with cell to cell signaling. The cell wall is a tough, yet flexible layer that surrounds the cell membrane of plant cells.Continue Reading
Cell walls have many functions. Their main function is to give the cell rigidity and strength. This allows plants to grow tall and hold out their leaves in order to obtain light energy to drive photosynthetic reactions.
Another important function of cell walls is to act as a physical barrier to the plant. The cell wall of plants is semipermeable and allows certain solutes and nutrients to enter the cell. However, it does not allow pathogens into the plant. This helps prevent diseases from infecting plants.
Cell walls also help promote cell-to-cell signaling through their cell walls. Portions of cell walls known as oligosaccharides can act as plant hormones. These compounds form from cell walls and stimulate plant hormone production, protect plants from pathogenic attack and induce enzymatic changes within the plant cells. Cell walls also resist water pressure changes so that plants do not burst or shrivel up in times of floods or droughts.Learn more about Cells

The function of an onion cell is to organize the biological processes of an onion. The onion, like other complex organisms, has different cells. There are cells that make up its leaves and flowers, cells that make up the onion bulb and cells that make up its roots.Full Answer >
The shape of a cell dictates the function of that cell. This is more pertinent to animal cells that, unlike plant cells, do not have a rigid cell wall. A misshapen cell cannot properly perform its intended function.Full Answer >
Animal cells aren't all shaped the same way; the shape of a specific animal cell depends on its function and where it is in the body. Unlike plant cells, animal cells do not have rigid cell walls that limit them to a rectangular shape.Full Answer >
