Name two structures present only in plant cells and two present only in animal cells.

Answer
Structures found ONLY in plant cells:
- Cell wall: A rigid outer layer made of cellulose that provides structural support and protection
- Chloroplasts: Organelles containing chlorophyll that carry out photosynthesis
Structures found ONLY in animal cells:
- Centrioles: Cylindrical structures that play a crucial role in cell division by organizing spindle fibers
- Lysosomes: Membrane-bound organelles containing digestive enzymes that break down waste materials and cellular debris (though some plant cells have similar structures called vacuoles with lysosomal functions)
These structural differences reflect the different lifestyles and functional requirements of plant and animal cells. Plants need cell walls for support since they lack skeletons, and chloroplasts for food production, while animals need centrioles for their specific type of cell division and lysosomes for their particular metabolic needs.
