Plants have many important features that help them survive.
| | Name | Function |
| 1. | Flowers | Flowers are needed for reproduction. They are often coloured and have a smell to attract insects. Flowers make the pollen and eggs that are needed to produce seeds. The seeds grow into new plants. |
| 2. | Leaves | Leaves are needed for nutrition as they make food for the plant through a process called photosynthesis. This uses sunlight, water and carbon dioxide from the air to make food. |
| 3. | Stem | Stems are needed to hold the plant upright so it can get light. They also transport water and nutrients from the roots to the rest of the plant. |
| 4. | Roots | Roots are needed for support. They keep the plant anchored in the soil and prevent it from blowing away. Roots are also needed for nutrition as they have lots of tiny root hairs that soak up water and minerals from the soil. |
