What is a plant?

The different parts of a plant have different functions.

  • The roots of a plant take up water and nutrients from the soil. The roots also keep the plant steady and upright in the soil.
  • The stem carries water and nutrients to different parts of the plant.
  • The leaves use light from the sun, along with carbon dioxide from the air and water to make food for the plant. This process is called photosynthesis.
  • Some plants have flowers. These are involved in reproduction and produce seeds from which new plants grow.
