Study Notes
Sporogony (Asexual Reproduction by Spores)
- Sporogony is a type of asexual reproduction where a single cell (spore) can germinate directly into a new plant.
- A spore is a single cell containing cytoplasm, a nucleus, and a protective outer layer (thick coat).
- Spores are released from the mother plant when they mature and are dispersed by air.
- Spores germinate when they reach a suitable moist environment.
- The spore's coat ruptures as it absorbs moisture and divides several times through mitosis, growing into a new plant.
- Sporogony is observed in primitive plants like some algae, fungi (mushrooms and bread mold), and primitive animals like plasmodium. It is also seen in higher plants such as ferns.
