Animal cells have a cell membrane instead of a cell wall, making tissue flaccid. This means that it is soft, pliable and not as heavy as plant tissue. This is part of what enables animals to move. Plants have no skeleton or exoskeleton, and are held up by their tissue. The plant tissue is made up of cells with rigid cell walls. Animal cells anchor onto a skeleton, and have a flaccid cell membrane.

Another point of View:


The simple answer would be this: they don't need one. In the brutally competitive business of survival, expensive and unneeded things get dropped quickly.

More Information:

The cell wall structure provides a lot of support and stabilizes the overall structure of the plant. Cells can't move around. In animals, multiple interactions between cells and molecules around them (referred to as the extracellular matrix) help to hold everything in place but animals have no real equivalent to the, relatively rigid, cell wall.

The plant cell wall is important for resisting the fluid pressure that builds up in the plant cells, which is part of the mechanism by which they can stand upright. Animals need bones or an exoskeleton to achieve a similar result.

There are a couple of consequences of having a cell wall, and one of them is a decrease in mobility of the individual organism - animals move around much more than plants. This in turn affects the different ways that plants and animals respond to environmental changes.

Because the cell wall tends to limit the direction of cell growth, plant embryos tend to develop by having specialized groups of cells that divide, whereas animal embryos tend to grow in all directions and in all places at once.

Thus, genetically, animals appear to have traded the structural stability of the cell wall for the greater flexibility and increased mobility of the cell membrane. However, there are still many similarities between plant and animal cells.

Why does a plant cell have a cell wall and chlorophyll and an animal cell doesn't?

Its because the plant needs to be stable because it would be really floppy, and the animal cell does not because it can move around the animal and it does not need to be stabl

Do animal cells have cell walls?

No. Instead, they use the flexable membrane that envelopes the cell. Related Information: In multicellular animals, these membranes are internally supported by the contents

Why animal cell does not have cell wall?

cell wall is fully permeable and can allow anything to pass   through it .   cell membrane memebrane does not allow the entry and exit of any  type of substance throu

Why do animal cells not have cell walls?

Because they are contained inside an animal/human's body; the plants are outside in the distance, so they would need a cell wall to protect them.

Why doesn't the animal cell have a cell wall?

Animals have only cell membranes made up of phospholipid bilayer and protein which protect and hold together the cell and its parts, it does not need to provide the support th

Why animal cell do not has cell wall?

That is because animal cells do not require cell walls, since cell walls make a cell more rigid and animals need flexibility to survive.

Do animal cells have a cell wall?

No, animal cells do not have a cell wall. They do have a cell membrane, but not a cell wall. Plants have a cell wall of cellulose, Fungi of Chitin and Monera of carbohydrates

If animal cell has cell wall?

Animal cells do not have cell walls--only cell membranes. All cells have cell membranes made of a phospholipid bilayer.   Cell walls, which are located outside of a cell's
