The cell wall is an extra layer of protection for plant cells. The cell wall is stiff so as to keep the shape of the cell. Since plants must be stiff or else they will droop, having stiff cells makes that happen. Animal cells don't need to worry about having stiff cells because animal cells just float around throughout the organism...plant cells must be stiff and aligned next to each other.
Well, a cell wall gives the plant cell it's straight structure, which makes the plant stand up and animals can support there own weight and plants need protection that gives the cell wall and animals dont need that protection.
Plant cells have cell walls because they need the extra protection. This is because plant cells cannot move out of the way of danger like animals can.
it dose not have cell walls becuse they dont need them
Animals cells use a cell membrane rather than a cell wall. Animals have more active metabolisms than plants do, and therefore they need faster diffusion from cells to circulatory systems, than they would get with cell walls.
Because cell is what they need. Without cell, they wont live long. Animal and plant need cells just like us to live long.
Before answering this question, it is important to know the function of a cell wall. Cell walls are found in plants to provide rigidity to support the shape of the cell. Animals do not require those functions in cells, hence they do not need cell walls.
animal cell don't need cell wall because they have micro filaments and micro tubules to hold the shape of the cell.
A cell membrane. As animals have a skeleton, we do not need a cell wall, like plants.
because animals need to have bacteria enter their mouths to survive
There was no cell wall in the cheek cells because animals and human cells do not contain a cell wall; they only have a cell membrane. Cell walls can be found in plant cells
Animals cells don't have cell walls because they don't need to make photosynthesis
Plant cells have cell walls. Animal cells do not. The reason why animals do not have cell walls is so that we are flexible enough to move around (which plants do not need to do).
