Plant nutrition

  1. 1. PLANT NUTRITION
  2. 2. RESPIRATION ● ● ● Plants breathe. They take oxygen from the air and release carbon dioxide. This process takes place in leaves.
  3. 3. Plant nutrition ● ● Plants are autotrophs: they make its own food. To make food, plants need: sunlight, carbon dioxide, water and minerals.
  4. 4. Water and minerals ● ● ● In the soil, minerals dissolve in water. Plants absorb this water through their roots. These nutrients, raw sap, travel up the stem to the leaves.
  5. 5. PHOTOSYNTHESIS ● Photosynthesis enables plants to make food from sunlight, carbon dioxide, water and minerals.
  6. 6. PHOTOSYNTHESIS ● ● Photosynthesis takes places in the leaves. Raw sap mixes with carbon dioxide and becomes elaborated sap.
  7. 7. PHOTOSYNTHESIS ● ● ● This elaborated sap is the plant´s food. Sunlight is essential for photosynthesis. During photosynthesis, plants release oxygen.
