Synzoospore is found in
1 Ulothrix
2 Volvox
3 Vaucheria
4 Oedogonium
Explanation:
Vaucheria grows in shallow freshwater or marine environments. In vaucheria, the multiflagellate compound zoospores, also known as synzoopores or conidiospores which are developed in these genus, usually in aquatic forms. A single compound zoospores develops in a single zoosporangium. Any distal branch of the thallus may convert into a zoosparangium. It is multi-flagellate. The zoospore swims for about 15 to 20 minutes. In Vaucheria, food is stored as oil globules.

In which of the following, all listed genera belong to the same class of algae?
1 Chara, Fucus, Polysiphonia
2 Volvox, Spirogyra, Chlamydomonas
3 Porphyra, Ectocarpus, Ulothrix
4 Sargassum, Laminaria, Gracillaria
Explanation:
Algae is the most primitive group of kingdom plantae. Alage further divided in to mainly three classes. Chlorophyceae (green algae), Rhodophyceae (red algae), and phaeophyceae (brown algae). Volvox, Spirogyra, Chlamydomonas belongs to same class chlorophyceae. Laminaria, Saragassum, Ectocarpus are members of brown algae. Polysiphonia, Porphyra, Gracilaria are members of red algae. Ulothrix is also a green algae.

In Spirogyra a brief period of tetranucleate condition is found in:
1 hold fast
2 gametangium
3 vegetative cell
4 germinating zygote
Explanation:
Spirogyra is an example of the Chlorophyceae. It is an unbranched, filamentous alga that is commonly found in freshwater. In Spirogyra, the asexual reproduction takes place through flagellated zoospores, the vegetative reproduction takes place through fragmentation, and the sexual reproduction takes place through conjugation. It takes place through the fusion of two non-ciliated gametes. The fusion of both kinds of gametes results in the formation of zygospores. The germinating diploid zygospores undergo meiosis to maintain the haploid. Condition, thus, in this condition, a tetranucleate condition is found for a brief period.
