Main Difference between Animal and Plant Cell:
Animal Cell:
- Lacks chloroplasts
- Small vacuoles
- Irregular shape
- Centrioles present
- No cell wall
Plant Cell:
- Contains chloroplasts
- Large central vacuole
- Regular shape
- No centrioles
- Cell wall present

Key Differences:
1. Chloroplasts: One of the main differences between animal and plant cells is the presence of chloroplasts. Chloroplasts are only found in plant cells and are responsible for photosynthesis, converting sunlight into energy.
2. Vacuoles: Plant cells have a large central vacuole that stores water, nutrients, and waste products. In contrast, animal cells have several small vacuoles scattered throughout the cytoplasm.
3. Cell Shape: Plant cells have a regular shape due to the rigid cell wall that surrounds them, providing structural support. Animal cells have a more irregular shape as they lack a cell wall.
4. Centrioles: Animal cells contain centrioles, which are involved in cell division and the formation of the spindle fibers. Plant cells do not have centrioles.
5. Cell Wall: Plant cells have a cell wall made of cellulose, providing protection and support. Animal cells do not have a cell wall, giving them more flexibility in shape and movement.
In summary, while animal and plant cells share many similarities in terms of organelles like ribosomes, endoplasmic reticulum, and chromosomes, the presence or absence of certain structures like chloroplasts, vacuoles, cell shape, centrioles, and cell walls are key differences that distinguish the two cell types.
