Animal cells do not have cell walls because they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if each cell has its own exoskeleton. This rigidity allows plants to stand upright without the need for bones .
Hereof, why don t animal cells have cell walls and chloroplasts?
Animal cells don`t have a dividing cell wall like plant cells do, but both do have plasma membranes. Plants cells use photosynthesis from the sun, which requires them to have chloroplast filled with chlorophyll to complete this function; animal cells do not have chloroplasts. Chlorophyll also helps make plants green.
Secondly, what would happen if animals have cell wall? Well if you mean animal cells having a rigid cell wall like that of plant cells a few things would happen: Cells would not be able to transport material in and out of the cell as easily with a cell wall (endocytosis and exocytosis especially would be hampered).
Keeping this in consideration, do animal cells have a cell wall?
Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall.
What would happen without a cell wall?
The cell wall provides the cell with protection from all the unfavorable conditions. Without the cell wall, the plant cell will collapse. Uptake of nutrients would be tough and the cell would be without any protection. Hence the plant would eventually die.
