Similarities between plant and animal cells:

1. Both have a cell membrane: This acts as a barrier, controlling what enters and exits the cell.

2. Both have cytoplasm: This gel-like substance fills the cell and houses the organelles.

3. Both have ribosomes: These are responsible for protein synthesis.

Differences between plant and animal cells:

1. Plant cells have a cell wall: This rigid structure provides support and shape. Animal cells lack this.

2. Plant cells have chloroplasts: These organelles contain chlorophyll, which allows the plant to perform photosynthesis. Animal cells lack this.
