Describe binary fission in Amoeba and budding in Hydra with labelled diagrams. Give two advantages of vegetative propagation.

1. 1 · Define in one line. Asexual reproduction produces new individuals from a single parent, without germ cells.
2. 2 · Binary fission in Amoeba. The nucleus divides, then the cytoplasm divides, giving two daughter cells.
3. 3 · Budding in Hydra. A bud forms at one spot by repeated cell division, develops tentacles, and detaches as a new Hydra.
4. 4 · Draw both. [Diagram: four stages of binary fission in Amoeba; stages of budding in Hydra with bud and tentacles labelled]
5. 5 · Vegetative propagation.
   • New plants grow from a root, stem or leaf.
   • Plants flower and fruit earlier.
   • Seedless plants such as banana can be grown.
   • Offspring keep the parent's traits.
6. 6 · Link to daily life. Gardeners grow roses and money plants from cuttings.
7. 7 · Close in one line. Asexual methods are quick and give offspring very like the parent.

Scoring tip: Number the stages in your diagrams, and write that the nucleus divides before the cytoplasm.
