9
Q
Nitrate deficiency
A
- short plant, poor root growth (unable to grow tissues)
- prone to disease (unable to repair tissues)
10
Q
Phosphate deficiency
A
- poor root growth (unable to make new cells)
11
Q
Potassium deficiency
A
- discoloured leaves (unable to photosynthesise or respire)
- no fruit/flowers (plant putting energy into survival)
12
Q
Magnesium deficiency
A
- not green (no chlorophyll (green pigment))
- no photosynthesis → no light energy absorbed → no glucose → no energy
