This module covers how flowering plants make new plants. You will label a flower by the job each part does, separate pollination from fertilisation, follow the ovule to a seed and the ovary to a fruit, compare sexual with asexual reproduction, and read germination experiments.
Check the current Cambridge IGCSE Biology 0610 syllabus for the exact wording in your exam year. Our Biology learning guide shows where this module sits among the others.
What should you already know?
You should know the basic idea of a cell and a nucleus from cells and microscopy. It also helps to know that seedlings make their own food later, which links to plant nutrition. Variation and inheritance are covered properly in cell division and inheritance.
An orienting example
A bee visits a flower, then a second flower of the same species. Three weeks later the second flower has a swollen green fruit with five seeds inside. Explain how the seeds formed.
Step 1, pollination: pollen from the first flower’s anther stuck to the bee. It was transferred to the stigma of the second flower.
Step 2, pollen tube: a pollen grain grew a tube down the style to the ovary and into an ovule.
Step 3, fertilisation: the male nucleus from the pollen fused with the female nucleus in the ovule. The fertilised ovule became a seed. Five fertilised ovules gave five seeds.
Step 4, fruit: the ovary wall developed into the fruit around the seeds.
That one answer used structure, sequence and cause and effect. It is a good picture of how the five lessons fit together.
In which order should you study it?
- Identify flower structures by role: every later step is described using these parts.
- Distinguish pollination from fertilisation: the pair students swap most easily, so fix it early.
- Explain seed and fruit formation: follows what each flower part becomes.
- Compare sexual and asexual propagation conceptually: uses the earlier lessons to explain why offspring differ or match.
- Interpret germination results with controlled conditions: moves from structure to experiments and fair testing.
Then use the plant reproduction practice set to mix all five skills.
Which traps catch students most?
- Writing that pollination is the fusion of gametes. It is only the transfer of pollen.
- Calling the whole flower “male” or “female” instead of naming the anther and the carpel.
- Saying the ovary becomes the seed. The ovule becomes the seed and the ovary becomes the fruit.
- Giving a germination result without saying which variable was changed and which were kept the same.
- Listing features of a wind-pollinated flower without linking each to its job.
How should you use the practice set?
Try each question on paper first, with the book closed. Write the answer in full sentences, then compare it with the worked answer. The practice page routes each type of slip back to the lesson that repairs it.
When the parts, the sequence and the experiments make sense together, you can explain most plant reproduction questions from first principles. If they do not yet, online one-to-one Biology tuition gives you a teacher who can trace the gap from your own written answers.
