Choose the correct one for basidiomycetes from given statements.
(i) They grow in soil, on logs and tree stumps and in living plant bodies as parasites.
(ii) The asexual spores are generally found and vegetative reproduction by fragmentation is common.
(iii) Sex organs are absent, but plasmogamy is brought about by fusion of two somatic cells of different strains.
(iv) Karyogamy and meiosis take place in the basidium producing eight basidiospores.
(v) The basidiospores are exogenously produced on the basidium.
Text Solution
Verified by ExpertsC
(i) Correct: They inhabit soil, logs, and tree stumps, or act as parasites within living plant bodies.
(iii) Correct: They lack specialized sex organs. Sexual reproduction (plasmogamy) occurs through the fusion of two somatic or vegetative cells of different strains.
(v) Correct: Unlike Ascomycetes, the sexual spores (basidiospores) in Basidiomycetes are produced exogenously (externally) on the basidium.
(vi) Correct: Basidia are typically clustered into complex fruiting bodies known as basidiocarps.
