- A Spirogyra - Motile gametes
- B Sargassum - Chlorophyll
- C Basidiomycetes - Puffballs
- D Nostoc - Water blooms
Answer & Solution
Correct Answer
(A) Spirogyra - Motile gametes
Step-by-step Solution
Detailed explanation
(a) : In Spirogyra, gametes are nonmotile and sexual reproduction takes place by conjugation. Sargassum belongs to Phaeophyceae group of algae. They are commonly called as ‘brown algae’ and contain photosynthetic pigments chlorophyll a andc. Puffballs are Basidomycetes with a stalked rounded structure that sends out puffs of spores, e.g., Lycoperdon oblongisporum. Nostoc is a colonial cyanobacterium. It enriches its habitat with nitrogen by fixing atmospheric nitrogen and also causes water bloom.
