The product of conjugation in Spirogyra or fertilization of Chlamydomonas is
1 zygospore
2 zoospore
3 oospore
4 carpospore
Explanation:
Zygospore is the end result of conjugation in spirogyra or fertilization in chlamydomonas. Both are members of the green alga family in which gametes combine to produce zygotes, which then grow into zygospores with strong walls.

In chlamydomonas the life cycle:
1 haplontic
2 diplobiontic
3 isomorphic
4 haplodiplontic
Explanation:
The life cycle of the chlamydomonas is haplontic. This is the simplest and most primitive type of life cycle. The main vegetative plant body is haploid (gametophyte). It bears haploid gametes. The gametic fusion which is known as syngamy produces zygote which is the only diploid phase (sporophyte) in the life cyle.

There exists a close association between the alga and the fungus within a lichen. The fungus
1 fixes the atmospheric nitrogen for the alga
2 provides protection, anchorage and absorption for the alga
3 provides food for the alga
4 releases oxygen for the alga
Explanation:
There exists a close association between the alga and the fungus with in a lichen. The fungus provides protection anchorage and absorption for the alga and blue green algae provide food and nutrition obtained by photosynthesis.

A ring of multicilliate zoogonidium is found in
1 Ulothrix
2 Zygnema
3 Oedogonium
4 Chara
Explanation:
The alga oedogonium contains a ring of multinucleotide zoogonidium. A zoogonidium is a photosynthetic cell in an algae that contains spores for reproduction. The zoospores are enclosed in a zoosporangium produced on the vegetative cells. The zoospores have a ring of flagella on the base. The zoospores are released from the vesicles and they float freely for some time to find a substratum and start dividing to form filaments once they find a substratum.
