Review Main Idea Why are animal and plant cells different? All cells have structures which work together to keep the cell alive. Because they cannot move around, plants need cell structures that help them to conserve water and make their own food. Animals don’t need these structures. Animal cells have to be more flexible to allow the animals to move around.

Review Main Idea What are cells? Cells are the smallest units of a living that can carry out the basic processes of life.

Review Summarize What does the cell wall do in plants? The cell wall protects plants’ cells and gives them their shape. It lets food and waste move into and out of the cell. It provides extra support for the plant. The cell wall protects plants’ cells and gives them shape and support, while allowing food and waste to move into and out of the cell.
