Biology Question on Algae
Algae, which form motile colony, is
A
Volvox
B
Nostoc
C
Spirogyra
D
Chlamydomonas
Answer
Volvox
Explanation
Solution
The correct answer is option (A): Volvox
The algae that forms a motile colony is Volvox. Volvox is a type of green algae that consists of individual cells working together in a spherical colony. These cells are interconnected by thin strands of cytoplasm and can move as a coordinated unit through the use of flagella. This motility allows Volvox colonies to move in a coordinated manner in water bodies. The other options listed, Nostoc, Spirogyra, and Chlamydomonas, do not form motile colonies like Volvox does.
