Observe: Function of the Parts of a Plant

Now that you have learned that the four main parts of a plant are roots, stem, leaves, and flowers, it is time to learn their functions. Each part serves a special purpose to allow the plant to grow and live. Think about how your body has many complex structures and parts that work together to allow you to survive and grow. If one part stops working, then your whole body can be affected. This is true in plants as well!

Roots: 
  • Take in water and minerals.
  • Anchor the plant.

Stem:
  • Carries water and minerals from the roots to the rest of the plant.
  • Carries food from the leaves to the rest of the plant.
  • Helps the plant stand upright (to get more sunlight to the leaves).

Flower:
  • Reproductive parts of the plant.
  • Pollinated flowers turn into fruit, or seeds.
Leaves:
  • Make food for the rest of the plant (photosynthesis occurs here).
  • Take in, and give out air.
