There are a number of reasons:
Plants cannot move and thus require more protection than animals (unicellular and multi-cellular) which are able to move away from danger. Cell walls provide structural strength against mechanical damage as well as invasion from fungi and bacterial pathogens.
Plants do not have a central or exoskeleton like animals and insects and have to rely on internal structural strength to support themselves. This enables them to grow towards light, water or nutrient sources.
Plant cells need a cell wall to maintain shape, structure and rigidity. Animal cells don't need cell walls because they have micro filaments and micro tubules to hold the shape of the cell.
The cell wall of the plant cell is made up of cellulose. Cellulose is a complex carbohydrate.
Plant cells need cell walls in order to hold their structure, shape, and rigidity. Animal cells do not need cell walls because they have microfilaments and microtubules that hold the cell's shape.
Because plants lost their ipods and became An Hero. who is doing this stop go get your jollies on mypace
because the cell wall protects what enters and leaves the cell, so therefore the animal cell has skin to protect, when the animals have sex the cells come together to have chromosones!
Plant cells have cell walls as plants do not have a skeletal system like animals to support them.
because Animals have bones to support thim... the cell wall is used to support the plant
Plant cells have certain specialized organelles that animal cells do not need. These organelles are the cell wall and chloroplasts.
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 stablised. Animal cells do not have chlorophyll because they don't need it. Plant cells need them because they take in sunlight and turn it into a sugar that is used for food for energy. Animal cells do not get their energy from the sun directly, they get it from oxygen. Animal cells do not photosythesise, which is what chlorophyll is for.
No, only plants have a cell wall
No. Plant and Animal Cells both have Cell Membranes. Plants cells have an extra membrane reffered to as the "Cell Wall". This helps the plant keep its shape. Without it, the plant will be very droopy. Animal cells don't need celll walls b/c they have cells specifically designed for structure of the animal. (Bone cells, muscle cells etc.)
no,cheeks do not have cell walls because plants have cell walls to let protein and waste in and out while an animal cell just sits there.No, only plant cells have cell walls.Well,kind of.No only plant cells have cell walls.
Plant cells have vacuoles. And only plant cells, animal cells have no need for them and if they do have them, they are very, very small.
An animal cell actually has less things than plant cells. Plant cells have cell walls used to hold the cells up and keep them sturdy while animal cells do not because it would make animals too stiff to move. Plant cells have the cell walls because they need to stand up and don't need to move.

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).
They have different shapes. Animal cells are circular, and plant cells are rectangular. Sorry I don't know any other way to check. You'd need a microscope. **This is wrong. the real answer is that animal cells have centrisomes while plant cells have chloroplasts and rigid cell walls.

No, only plants have a cell wall
A animal cell has a Cell Membrane to protect it, but a plant cell has a Cell Wall that also protects it. Ask me any more questions you need!

because cell walls of the plant cells makes the plant stands straight
simple because we don't need it.
