The three answer choices that would indicate the organism is a plant, not an animal, are:
- Chloroplasts - These organelles are involved in photosynthesis and are found in plant cells.
- Cell wall - Plant cells have a rigid cell wall made of cellulose, which is not present in animal cells.
- Central vacuole - Plant cells typically have a large central vacuole that helps maintain cell turgor pressure and stores substances.
The other options, nucleus and endoplasmic reticulum, are found in both plant and animal cells.
