(a) (i) hyphae
(ii) sporangium
(b) Spores are covered by thick walls that protect them from dehydration under unfavourable conditions.
——> Spores that are released from sporangia are distributed evenly by agents like air to far-off places to avoid competition at one place. These spores , when fall on ground, grow into new rhizopus. This is an example of spore formation ( asexual reproduction )
