Name the way of reproduction:
- (a) A small outgrowth on a Hydra grows and then breaks off.
- (b) A filament of Spirogyra breaks into pieces and each piece grows.
- (c) A Paramecium splits into two.
- (d) A green, powdery mould spreads over an old orange.
- (e) An arm of a starfish that breaks off with part of the centre grows into a whole starfish.
Need a reminder? The key ideaShow
Reproduction makes new individuals like the parents, with two parents (sexual) or one (asexual). Asexual ways: binary fission (Amoeba, bacteria), budding (yeast, Hydra), fragmentation (fungi, filamentous algae, protonema of mosses), spores (fungi) and regeneration (Planaria). Sterile organisms are alive, so reproduction is not a defining feature.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
(a) Budding.
(b) Fragmentation.
(c) Binary fission.
(d) Spores, made in millions by the mould, a fungus.
(e) Regeneration.
Answer: budding, fragmentation, binary fission, spores and regeneration.
