Mineral Requirements
Core
• Describe the importance of:
• nitrate ions for protein synthesis
• magnesium ions for chlorophyll synthesis
Extended
• Explain the effects of nitrate ion and
magnesium ion deficiency on plant growth
Nitrate ions and Magnesium ions are taken from the soil by either diffusion or active transport. Nitrate ions are primarily used for making proteins whereas magnesium ions are primarily used to produce chlorophyll.
A lack of Nitrate ions will result in not enough proteins being produced, and will result in weak growth/yellow leaves. A lack of Magnesium ions will result in not enough chlorophyll being produced, limiting the rate of photosynthesis and resulting in yellowing between the veins in the leaves of plants.
