Basic Needs Of Plants

Basic Needs Of Plants
  • Air
  • Water
  • Sunlight
Plants Need Air
Plants need oxigen from the air for respiration. Plants also need carbondioxide from the air to make food. Plants make food throgh
photosynthesis. Plants will die without air.

Plants Need Water
Plants absorb water from the soil through their roots. Plants need water for making food during photosynthesis, transporting food and minerals to the plant tissues.

Plants Need Sunlight
Green plants can make their own food through photosynthesis. Sunlight is necessary for photosynthesis. Without sunlight plants will die. Sunlight provides the energy needed for water to combine with carbon dioxide to produce glucose in the leaves. Oxygen is produced as a by-product.
