List three differences between plant and animal cells.

• 3. Animal cells have a large central vacuole, while plant cells have smaller vacuoles or none at all.

• 1. Animal cells have a cell wall, while plant cells do not.

Explain the role of the nucleus in a cell.

• The nucleus is involved in breaking down food particles in the cell.

• The nucleus is responsible for producing energy in the cell.

• The nucleus controls the cell's activities and stores genetic material.

• The nucleus is where waste materials are stored in the cell.
