Question

Fire Algae belongs to group-

(2) Bacillariophyta
(3) Euglenophyta
(4) Rhodopyta

Answer 1

Answer:

option 1 .

Explanation:

Pyrrophyta is reddish brown unicellular dinoflagellates with/without cellulosic cell wall. Dinoflagellates are the bioluminescent algae. They have pigment luciferin which is acted upon by the enzyme luciferase causing production of light without any heat, thus the name fire algae.

Euglenophyta are unicellular autotrophic algae characterized by absence of cell wall and presence of pellicle, they are not bioluminescent.
