Plant nutrition covers the minerals plants take from the soil and how scientists find out what each one does. This section has four lessons and a practice set, and belongs to the SPM Biology guide.
What does this section cover?
Start with explaining mineral requirements, the role of each mineral. Then interpret deficiency evidence in curriculum examples, working from symptom to mineral.
Next, comparing nutritional adaptations covers plants that gain nutrients in unusual ways. The fourth lesson is planning a fair plant nutrition investigation, and the practice set mixes all four.
One yellow leaf, four questions
An original observation: a seedling in a pot has yellow older leaves and slow growth.
| Question | What to do | Lesson |
|---|---|---|
| Which mineral might be short? | Link symptom to role | Mineral requirements |
| Is the evidence enough? | Check the pattern and controls | Deficiency evidence |
| Could the plant gain it differently? | Compare adaptations | Nutritional adaptations |
| How would you test it? | Plan with one variable | Fair investigation |
One symptom raises four different questions, and each needs its own skill.
Who should start where?
If you do not know the mineral roles, start with the first lesson. If you know the roles but mix up symptoms, go to the deficiency lesson.
The plan-an-investigation lesson suits anyone who loses marks on fair-test questions. The photosynthesis links are in leaves and photosynthesis.
How do the parts connect?
A mineral has a role, a missing mineral gives a symptom, and a test of the link needs a fair design. Some plants meet their needs differently, which is why the adaptation lesson sits between evidence and investigation.
Logging slips in the mistake log tool shows which part needs another pass.
If the step from symptom to mineral keeps going wrong, SPM Biology one-to-one tuition lets a teacher work through it with you on new examples.
