Plant and Animal Structures and Their Functions

How are plants and animals alike?

How are they different?

• They both have needs like water and food.

• They both grow and reproduce.

• They both have parts and structures that help them stay alive.

• Animals need to get food to eat.

• Plants make their own food using energy from the sun, water and CO2.

• They do not have the same parts or structures.

• protection
