Question

Bioluminescence in Ctenophores is

• A. The property of living organisms to absorb light
• B. The property of organisms to emit light
• C. The property of organisms to produce energy
• D. The property of organisms to attract mating organism

Answer 1

The correct option is B The property of organisms to emit light

Ctenophores, commonly known as sea walnuts or comb jellies are exclusively marine, radially symmetrical, diploblastic organisms with tissue level of organization. The body bears eight external rows of ciliated comb plates, which help in locomotion. Digestion is both extracellular and intracellular. Bioluminescence (the property of a living organism to emit light) is well-marked in ctenophores. Sexes are not separate. Reproduction takes place only by sexual means fertilizations is external with indirect development. Examples: Pleurobrachia and Ctenoplana.
