Show Answer
Answer:
Correct Answer: D
Solution:
Nostoc species are multicellular, filamentous cyanobacteria. These organisms have the ability to fix atmospheric nitrogen with the help of the enzyme nitrogenase present in the heterocysts.
The heterocysts are the specialised cells in which the nitrogenase enzyme is present.
Fronds are found in pteridophytes.
The male gametes in the angiosperms do not have cilia.
The basidiomycetes is the group of fungus which produces basidiospores.
