Question : What is a spore ? Explain asexual reproduction through spore formation.

Answer»

Solution :Spore is a microscopic reproductive unit of plant which is COVERED by a protective thick wall.
ASEXUAL reproduction through spore: A bread mould e.g., Rhizopus is a simple multi-cellular organism.
`rarr` It has thread-like STRUCTURE called hypha. Hyphae are not reproductive parts.
`rarr` The fungal hypha develops an enlarged or tiny blob called sporangium.
`rarr` The spores are produced and matured in sporangium.
`rarr` The spores are covered with thick WALLS which protect them until they come into contact with moist surface. Under favourable condition spores can begin to grow and eventually DEVELOP into new Rhizopus individuals.
