  • Minerals Needed for Healthy for Healthy Growth
    • Plants need Three Main Minerals
      • 1) Nitrates: Contain nitrogen for making amino acids and proteins. These are needed for cell growth
        • If the plant does not get enough nitrates, its growth will be poor and it will have yellow leaves
      • 2) Phosphates : Needed for respiration and growth. Contains phosphorus for making DNA and cell membranes
        • Plants without enough phosphate have poor root growth and discoloured leaves
      • 3) Potassium: To help the enzymes needed for photosynthesis and respiration.
        • If there is not enough potassium in the soil, plants have poor flower + fruit growth + discloured leaves
    • Magnesium is also needed in small amounts, however it is still very important
      • It is required for making chlorophyll which is needed for photosynthesis.
        • Plants without enough magnesium have yellow leaves
    • Root Hairs
      • They give the plant a big surface area for absorbing minerals in the soil
      • Concentration of minerals in soil is often low, concentration is normally higher in root hair cell than the soil around it
        • Active Transport
          • Uses energy from respiration to help the plant pull minerals into the root
