Critical thinking

• Most plants do not have structures for eating. What might be a reason for this?

• Plants do not eat food. They make their food from energy from the Sun.

What is a root?

• Plants take in water through their roots

• Roots also hold a structure in place

• Carrots and radishes have one thick root called a taproot.

Roots

• Not all plants have one big root (taproot) others have a web design

Stems

• Stems are structures that hold up a plant

• Stems hold up leaves so that they get sunlight

• Stem carries water, nutrients and food throughout the plant

Question time

• What are the three functions of a stem?

• Name one root we can eat.

• What is a stem?

Leaves

• Many shapes and sizes

• Leaf is where a plant makes its food

• Photosynthesis is the process in which plants make their own food

Photosynthesis

• Process in which plants make their own food
