Answer:
a) -Cell Wall
- Plastids such as Chloroplasts
b) Please refer to Explanation
Step-by-step explanation:
Organelle structure and components are mostly similar with both plant and animal cells, but in certain areas the differ, because they do different things to survive.
One of the ways they differ is their organelle content. There are some organalles that Plant cells have that Animal cells do not.
Two examples of them are;
- Cell Wall
- Plastids such as Chloroplasts
b) Cell Wall - Why does an Animal cell not need it?
Animal cells do not need cell walls for one reason, bones or rather a lack thereof.
Cell walls act as a sort of Exoskeleton for cells as they maintain the cell's shape. This leads to a rigidity that enables the plant to stand up on its own without the need for bones like in animals.
