Activity 8.2 How do Organisms Reproduce explanation
Bread mould with spores

Observation: Rhizopus sporulate and releases new spores from sporangium.

Explanation: Just like sugar favours yeast, carbohydrates in bread and presence of water favours rhizopus. Rhizopus is a fungus which looks green and black. We also call them bread mould.

Rhizopus in a moist environment grows rapidly and multiplies by spore formation. The green mould which we see in a stale bread is because of the fast growth and reproduction of Rhizopus.
