Answer 1

The correct option is E A- iv, B- iii, C- ii, D- i

Chrysophytes are found in freshwater and saltwater and most of them are photosynthetic (e.g., diatoms). Dinoflagellates are photosynthetic protists and some members are capable of producing light through bioluminescence (e.g. Noctiluca and Gonyaulax ). Euglenoids have a shape-changing motion, called metaboly. They are either single or colonial and can swim or glide with the help of flagella (e.g. Euglena). Protozoa include Paramecium, Amoeba, Giardia, etc.
