WAEC Biology 2015 Theory — Question 1

Model answer

Reproduction in Rhizopus can occur sexually (by conjugation) or asexually (by spore formation). In conjugation, two compatible hyphae strains come together to form a zygospore. The zygospore then germinates and develops into a new plant under favourable conditions. Note that conjugation also occurs in other organisms such as Mucor and Spirogyra.
