Question 3(b)
[Maximum number: 3]
Photosynthesis is the process green plants use to convert light energy into chemical energy.
Plants produce carbohydrates using photosynthesis.
Explain why mineral ions are also required for healthy plant growth.
Edexcel IGCSE Biology 2.22 Mineral Ions Required by Plants
Practise linking nitrate and magnesium ions to amino acids, chlorophyll, healthy growth and visible deficiency symptoms.
How this is tested
- link nitrate ions to amino-acid and protein synthesis for plant growth
- link magnesium ions to chlorophyll production and photosynthetic capacity
- interpret controlled mineral-solution results using leaf colour, size and growth data
