(a) Name the following :
(i) Thread like non-reproductive structures present in Rhizopus.
(ii) 'Blobs' that develop at the tips of the non- reproductive threads in Rhizopus.
(b) Explain how these structures protect themselves and what is the function of the structures released from the 'blobs' in Rhizopus.

Explanation

(a) (i) Hyphae
(ii) Sporangia.
(b) Each sporangium contains hundreds of black-spots and these spores are dispersed into air to germinate on suitable substrate.
Spores have an outer thick wall that protects them in adverse conditions until they come in contact with another moist surface and begin to grow.
Function They germinate into new individuals under favourable conditions.
