Question

Many Cnidarians have two distinct life stages called -

• A. gametophyte and sporophyte
• B. pupae and larvae
• C. polyp and medusa
• D. larvae and adult

Answer 1

The correct option is C polyp and medusa

Cnidarians generally exhibit polymorphism and have thus, two distinct life stages called polyp and medusa. Some of them exist either as a polyp or medusa all throughout their life, while some exhibit alternation of generation between the two forms. Polyp is sessile or non-motile form while medusa is the free floating form.
