why do only plant cells have cell wall but not the animal cells?

Solution

Dear Student,
Plant cells have cell wall because plants do not move from one place to another and hence they require rigidity which is provided by the cell wall but animal cells move. The cell wall if present in the animal cell will be a hinderance to movement.
Hope this answers your question,
Cheers!!

Q. Why do plant cells need a cell wall, and animal cells do not?

Pick the correct set of difference between plant and animal cells from the following table:

$\begin{matrix} Animal cells & Plant cells i. Animal cells have large single vacuole & Plant cells have many small vacuoles ii. Animal cells do not have plastids & Plant cells have plastids including chloroplast iii. Animal cells do not have cell wall & Plant cells have cell wall outside the plasma membrane iv. Animal cells are green in colour & Plant cells are not colored v. Lysosomes are always present & Lysosomes are rare \end{matrix}$

Pick the correct set of difference(s) between plant and animal cells from the following table.

Number	Animal cell	Plant cell
i	Animal cells have large single vacuole	Plant cells have many small vacuoles
ii	Animal cells do not have plastids	Plant cells have plastids including chloroplast
iii	Animal cells do not have cell wall	Plant cells have cell wall outside the plasma membrane
iv	Animal cells are green in colour	Plant cells are not coloured
