Which one of the following is wrongly matched?
1 Spirogyra – Motile gametes
2 Sargassum – Chlorophyll c
3 Basidiomycetes – Puffballs
4 Nostoc – Water blooms
Explanation:
In spirogyra, gamete is non-motile and sexually reproduces by conjugation. Sargassum belongs to phaeophyceae mainly consisting of chlorophyll a and c pigments, Puff balls belongs to Basidiomycetes. Nostoc forms water blooms.
