A Cell wall surrounds a single Cell membrane.
A Cell wall is a tough, usually flexible but sometimes fairly rigid layer that surrounds some types of Cells. It is located outside the Cell membrane and provides these Cells with structural support and protection, and also acts as a filtering mechanism. A major function of the cell wall is to act as a pressure vessel, preventing over-expansion when water enters the cell. They are found in plants, bacteria, fungi, algae, and some archaea. Animals and protozoa do not have cell walls.
The materials in a cell wall vary between species, and in plants and fungi also differ between cell types and developmental stages. In plants, the strongest component of the complex cell wall is a carbohydrate called cellulose, which is a polymer of glucose. In bacteria, peptidoglycan forms the cell wall. Archaean cell walls have various compositions, and may be formed of glycoprotein S-layers, pseudopeptidoglycan, or polysaccharides. Fungi possess cell walls made of the glucosamine polymer chitin, and algae typically possess walls made of glycoproteins and polysaccharides. Unusually, diatoms have a cell wall composed of silicic acid. Often, other accessory molecules are found anchored to the Cell wall.
Different groups (sometimes referred to as "species") of bacteria come in different sizes, and cells within different states of growth have different sizes, but a size of 1-10 micrometers is a middle range.
The average thickness of a cell membrane is between 7 and 9 nanometers. One micrometer is equal to 1000 nanometers.
Annie is that you?
yes it is my beloved
an animal cell is about 1.5 or 2 micrometers
they typically range from 0.1 um (micrometers)- several um
1.2KM
no it does not have a cell wall because it is single cellular
The cell wall supports and protects the plant cell.
One is a cell wall and one is a chloroplast.
The cell wall.But it is not only found in plants, both bacteria and fungi have cell walls too.
Yes, animal cells are surrounded by a cell membrane. anything going in or out of the cell must go through the cell membrane.

The only part of the cell that is made of cellulose is the rigid cell wall. The cell wall is a protective outer covering(only in plant cells) that protects the cell from many things, such as weather conditions etc.
The cell wall supports and protects the plant cell.
One is a cell wall and one is a chloroplast.

no a cell wall is in a plant cell a'n animal cell has a cell membrane and a plant has one big vacuole and the animal has many small ones

There is no cell wall in a animal cell but there is a cell wall in the plant cell.
the cell wall
For plant cells, there is a cell wall outside of the cell's membrane. Animal cells do not have walls, so there is no structure outside of the cell membrane.
