Many cells have a cell wall, but animal cells do not. Why might this be? a) Because animal cells do not need structural support b) Because animal cells are capable of movement c) Because animal cells can control osmotic pressure d) Because animal cells only exist in the multicellular form
Question
Many cells have a cell wall, but animal cells do not. Why might this be? a) Because animal cells do not need structural support b) Because animal cells are capable of movement c) Because animal cells can control osmotic pressure d) Because animal cells only exist in the multicellular form
Solution
The answer is b) Because animal cells are capable of movement.
Animal cells do not have a cell wall because they need to be flexible. This flexibility allows them to change shape which is necessary for movement. For example, human red blood cells are flexible so they can squeeze through the smallest blood vessels.
On the other hand, plant cells, which do have a cell wall, are stationary and need this extra support to maintain their shape. The cell wall also provides protection against mechanical and osmotic stress.
The other options are not entirely correct. While it's true that animal cells can control osmotic pressure and exist only in multicellular form, these are not the reasons why they lack a cell wall. And it's not accurate to say that animal cells do not need structural support at all; they do have a structure called the cytoskeleton for this purpose.
