3. Organelles
Special structures that perform necessary functions within the cell
Each organelle performs a different function within the cell
All cells (both Plant and Animal ) contain organelles

About the different cell
organelles
Tiny organs. Just like organs in your body you need them to function properly or else it will DIE.
