Question

Which of the following is not correctly matched?
A) Chlamydomonas – unicellular flagellated
B) Laminaria – flattered leaf like thallus
C) Chlorella – unicellular flagellated
D) Spirogyra – filamentous structure
E) Volvox – colonial, non-flagellated

Answer 1

Hint:Volvox is unicellular algae that live in a colony. Every cell of volvox has numerous flagella that form a ball kind of structure that’s why it is also named as “Globe algae”.

Complete answer:
>Chlamydomonas is a genus of algae consisting of around 325 species. Everyone is unicellular flagellated, found in stale water and on soggy soil, in seawater, freshwater and even in snow as "snow algae".
>Laminaria is a genus of 31 types of brown colored algae ordinarily called "kelp". Some species are categorized as tangle. This monetarily significant variety is described by leathered laminae, long and generally huge size. Their leaves appeared like thallus and flat.
>Chlorella is unicellular green algae having a place in the division Chlorophyta. It is circular fit as a fiddle, around 2 to 10 μm in width, and is without flagella. It contains the green photosynthetic colors chlorophyll-a and - b in its chloroplast.
>Spirogyra is filamentous charophyte green algae from order Zygnematales, named because of helical arrangement of the chloroplasts that are its genus's characteristics. It is regularly found in freshwater surroundings.
>Volvox belongs to the genus of chlorophytes, a kind of green algae. Volvox is unicellular algae that live in a colony. The colony is hollow with 500 to 20,000 single cells. Every volvox cell has two or more than its flagella. The flagella hit together to roll the ball through the water.

Thus, the correct answer is option (E) Volvox – colonial, non-flagellated is not correctly matched.

Note:- Laminaria is found in colder sea waters, for example, arctic regions. Preferring to remain in areas where there are rough shores, this permits the laminaria to connect. Because of the huge length of the Laminaria, they give assurance to animals that the untamed sea doesn't frequently give. Invertebrates are only one of the living beings that live among the algae.
-Volvox cells have chlorophyll and make their own food by the process of photosynthesis. Daughter colonies are little, dull green balls inside the volvox colony. At the point when the daughter colonies states develop, the parent ball blasts open and delivers the daughter colonies.
