Feb 22, 2016 · Explanation: Plant, fungi, algee and bacteria cells have cell walls. A rigid outer layer beyond the cell membrane that provided structural support for the cell. Answer link. Cell walls. Plant, fungi, algee and bacteria cells have cell walls. A rigid outer layer beyond the cell membrane that provided structural support for the cell. The rigid outer covering a plant cell is known as the cell wall. The cell wall is composed mainly of cellulose.The cell wall is a rigid layer that surrounds the plant cells. It is made up of cellulose. Cell wall is a characteristic feature to cells of plants. Plant cell walls are primarily made up of cellulose. It is located outside the cell membrane whose main function is to provide rigidity, strength, protection against mechanical stress and infection. The cell wall is a tough layer found on the outside of the plant cell that gives it strength and also maintains high turgidity. In plants, the cell wall contains mainly cellulose, along with other molecules like hemicellulose, pectin, and lignins. The composition of the plant cell wall differentiates it from the cell walls of other organisms.

It protects the plant from a variety of external factors, including pests, diseases, and environmental stressors such as drought and extreme temperatures.

In a plant cell the outer layer is a cell wall which is rigid and gives the plant its support and structure. Where as in an animal cell this layer is a plasma membrane. Another major difference between the two cell types is seen within the cell for only plant cells have chloroplasts and vacules.Indeed, today’s plant cells use tubular structures (up to hundreds of nm in diameter), called plasmodesmata, to connect neighboring cells across the cell wall in higher plant cells 12.
