Plant_vs_Animal_Cells.pptx GRADE 7 SCIENCE

Differentiate plant and animal cells based on their organelles.

1. Plant and Animal Cells A Simple Comparison Based on Organelles

2. Plant Cell Organelles • Has a cell wall made of cellulose for structure and protection. • Contains chloroplasts for photosynthesis. • Has a large central vacuole for storing water and maintaining pressure. • Contains plastids for pigment and starch storage.

3. Animal Cell Organelles • Lacks a cell wall, only a flexible cell membrane. • No chloroplasts, obtains energy from food instead. • Has small vacuoles (if any) instead of one large one. • Contains centrioles that help in cell division.

4. Key Differences Between Plant and Animal Cells • Cell wall: Present in plant, absent in animal. • Chloroplasts: Present in plant, absent in animal. • Vacuole: Large in plant, small or none in animal. • Centrioles: Present in animal, usually absent in plant.
