1. Cell Wall: Plant cells have a rigid cell wall made of cellulose that surrounds the cell membrane. This provides structural support and protection. Animal cells do not have cell walls.

2. Chloroplasts: Plant cells contain chloroplasts, which are organelles responsible for photosynthesis. Chloroplasts contain chlorophyll, which absorbs light energy to convert it into chemical energy. Animal cells do not have chloroplasts and cannot perform photosynthesis.
