Reproduction: How Life Continues
Class 9 · Science
3 ideas in Class 9 Science, explained in plain words, with games and quizzes to practise.
Asexual Reproduction and Plant Propagation
Part of: Asexual Reproduction and Plant Propagation
Asexual reproduction uses one parent and produces offspring that are genetically very similar to that parent. Some plants grow new individuals from stems, leaves or other vegetative parts.
Why it matters. It explains how growers can multiply plants with useful features without waiting for seeds.
Try it in two minutes
- Inspect a potato or ginger for buds.
- Look for nodes on a stem cutting.
- Discuss how a new plant can grow from a parent part.
Try at home. Notice plants grown from cuttings or other vegetative parts.
Meiosis, Flowers and Fertilisation
Part of: Meiosis, Flowers and Fertilisation
Meiosis forms gametes. In flowering plants, pollen reaches a stigma; after fertilisation, the fertilised egg becomes a zygote and develops, while ovules become seeds.
Why it matters. Following the steps helps explain how a flower can form fruit and seeds.
Try it in two minutes
- Find a flower and identify its pollen-bearing part.
- Trace where pollen must travel.
- Connect the ovule with seed formation after fertilisation.
Try at home. Observe flowers and notice features that may attract a pollinator.
Reproduction in Animals
Part of: Reproduction in Animals
Animals reproduce sexually when male and female gametes fuse. In some animals fertilisation happens outside the body; in others it occurs inside the female, and embryos develop in different ways.
Why it matters. These differences help make sense of how animals produce and protect their young.
Try it in two minutes
- Sort animal examples by where fertilisation occurs.
- Compare the number of eggs and level of protection described.
- Trace a fertilised egg into an embryo.
Try at home. Look for how different animals care for or protect developing young.
