How does a cell wall differ from a cell membrane?

Answer 1

A "cell wall" is found in plant cells, and a "cell membrane" is generally found in animals.

A "cell wall" is made of cellulose whereas a "cell membrane" is made up of lipids and proteins.

A "cell wall" is completely permeable and a "cell membrane" is partially permeable.

The cell membrane is on both an animal and plant cell, while a cell wall is a stiff 'box' shape enclosing a plant cell.

Analogy

Think of a cell membrane as a plastic bag, filled with clear jelly, with a large blob of modeling clay in it (the clay being the nucleus). This represents an animal cell.

Now add a small box and a few green blobs of clay to the inside of the bag (these are the plant cell's vacuole and chloroplasts). Put the plastic bag and its contents into a large box. This is a plant cell, and the big box is the cell wall.

Answer 2

cell wall -rigid,freely permeable,only one name,made of cellulose.cell membrane-flexible,selectively permeable,called palsma membrane,made of 2 layers of lipic molecules and one layer of protines.

Answer 3

1.Cell wall is found in plant cell and cell membrane is found in animal cells.

2.Cell membrane is covered by the cell wall which forms the outer most covering.

3.Cell wall is completely permeable whereas cell membrane is semi-permeable.

4.Cell wall is made up of cellulose and cell membrane is made up of lipids and proteins.

5.Cell membrane is also known as plasma lemma.

Answer 4

Most animal cells are contained within a cell membrane. Plant cells and most bacteria are contained within a cell wall. The differences in structure generally lend the cell wall greater structural rigidity than that of the cell membrane. On the other hand, the cell membrane allows the cell to be more deformable.

Answer 5

The cell membrane has small holes in it called pores that allow proteins and other materials come in and out of the cell. Also the cell wall is only located in plant cells, when the cell membrane is located in both plant and animal cells.

Answer 6

The cell membrane is in both an animal and plant cell, and a cell wall is a stiff 'box' shape enclosing a plant cell. Think of it as a plastic bag, filled with jelly, with blobs of plasticene in is, the plasticene being the nucleus and the jelly the chlorophyll. The plastic bag is a cell membrane. This is an animal cell. Now add a small box and a few more different colored blobs of plasticene inside the bag- these are the plant cell's vacuole and chloroplasts. Put the plastic bag and its contents into a large box- this is a plant cell. The big box is the cell wall.

Answer 7

cell walls provide structure as cell membrane provide letting nutrients in

Answer 8

Cell wall keeps the form of a plant cell

Answer 9

Cell wall keeps the form of a plant cell
