what is the function of the cell wall in a plant cell?
112572
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

It protects the cell from the external environment. It protects and maintains the internal environment of the cell. The cell wall is elastic. The cell membrane is non-elastic.

Cell walls made of cellulose are only found around plant cells and a few other organisms. Cellulose is a specialized sugar that is classified as a structural carbohydrate and not used for energy.

Among its roles in plant cell function, the central vacuole stores salts, minerals, nutrients, proteins, pigments, helps in plant growth, and plays an important structural role for the plant.

The cell wall of an onion cell functions as a structural part of the cell, offering support and protection for the fluids and organelles inside.

The cell wall of fungi is a dynamic structure that protects the cell from environmental stress and prevents from various effects that are caused due to changes in osmotic pressure. Biosynthesis is a unique feature of the fungal cell wall. They possess a complicated cellular structure.

The cell wall is an outer protective membrane in many cells including plants, fungi, algae, and bacteria. Animal cells do not have a cell wall. The main functions of the cell wall are to provide structure, support, and protection for the cell.

Cell wall. A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. ... Cell walls are present in most prokaryotes (except mollicute bacteria), in algae, fungi and eukaryotes including plants but are absent in animals.

Secondary cell walls provide additional protection to cells and rigidity and strength to the larger plant. These walls are constructed of layered sheaths of cellulose microfibrils, wherein the fibers are in parallel within each layer.

What is the function of the cell wall in the onion cell you looked at? It protects the cell and provides shape and support. What color and shape were the onion root cells? What organelles or cellular structures were common to all the different organisms looked at with the microscope?

Plasma Membrane is the phospholipid layer, found in all types of cells; it helps in protecting the protoplasm and checks the passage of molecules inside the cell, Though cell wall is found in the plant cell, fungi, bacteria only and protects the cell from external shocks, and provide rigidity and shape to the cell.
392203
Cell wall is made up of cellulose in plant and of peptidoglycan in bacterium and made up of chitin in fungi. Plasma membrane is made up of lipids proteins and small amount of carbohydrates. Cell wall is a rigid, thick structure (4-20 uM) and visible in light microscope.

The cell wall protects the cell, provides structural support, and gives shape to the cell while the central vacuole plays a key role in regulating the cell's concentration of water in changing environmental conditions. Chloroplasts are the organelles that carry out photosynthesis.

A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
558478
The cell wall is the tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells. It is outside the cell membrane and gives these cells support and protection, as well as acting as a filter.

Cell membrane is selectively permeable or semi- permeable allowing only certain molecules to pass through. Cell wall determines the cell shape and offers protection. ... Cell wall is present only in plant cell. Cell membrane is present in plant cells as well as in animal cell.
