In Spirogyra during the germination of zygospore how many haploid nuclei takes part?
1 Three
2 Two
3 One
4 All four
Explanation:
Spirogyra is a genus of filamentous charophyte green algae commonly known as water silk. It is very common in relatively clear eutropic developing slimy filamentous green masses. Zygospore is a triple layered with brownish-orange coloured outer layer. Zygospores in the bottom of pond rest till the return of favorable season. During germination, zygospore nucleus divides meiotically and out of four daughter nuclei formed three disintegrate, leaving only one haploid Nucleus. The zygospore germinates, the two outer cost line burst and a new filament is formed.

Which of the following groups of algae do not have eukaryotic organization ?
1 Green algae
2 Blue green algae
3 Golden brown algae
4 Red algae
Explanation:
Blue green algae do not have eukaryotic organization. Blue green algae are also called cyanobacteria. They are prokaryotes and also lack membrane-bound organelles like mitochondria, Golgi apparatus etc. Ex. Anabaena, Nostoc

Which one of the following is common to multicellular fungi, filamentous algae and protonema of mosses:
1 Mode of Nutrition
2 Multiplication by fragmentation
3 Diplontic life cycle
4 Members of kingdom plantae
Explanation:
Multiplication by fragmentation is common among filamentous algae and protonema of mosses all show multiplication by fragmentation. Fragmentation is mode of asexual reproduction that involves breaking the parent body into several fragments and each fragments fungi, filamentous algae and protonema of mosses show the fragments.
