- Roots keep the plant stable in the ground.
- Roots store food made by the plant`s leaves.
- Roots also take in water and materials called
minerals from the soil.

The plant gets nutrients from the water and minerals.
A nutrient is any material needed by living things for energy, growth, and repair.
Plants need nutrients to live and grow.

- Taproots grow deep into the soil toward earth`s center.
- Taproots take in water and nutrients from the soil.
- The roots also store food made by the plant.

- Fibrous root store food.
- Fibrous roots take in water and nutrients from the soil.
- Fibrous roots grow toward earth`s center.
-Fibrous roots grow longer than taproots.
- Fibrous roots grow close the surface to take in water after it rains.

How stems help plants
- Stems support the leaves, flowers, and fruits.- Stems grow up toward the light(main source of energy).- Stems have tiny tubes that move water and minerals from roots to the leaves.- other tubes move food from the leaves to the stems and roots.

cactus stems

are thick and waxy.(this keeps them from losing water(.
swell up to store water..
help cactus survive in a desert.
grow above ground.
