In which way are corals different from most other cnidarians?

Question

a. They exist only in the Medusa form.

b. They secrete a tough outer skeleton.

c. They reproduce only asexually.

d. They are photosynthetic.

Answer 1

b

A) Medusa (a jellyfish) is like most other cnidarians (a phylum generally made up of jellyfish and sea anemones)

B) is correct, because jellyfish don't have tough outer skeletons

C) Corals reproduce by both budding or fragmentation (asexual) and by sexual methods (similar species release sperm/egg all within a short time frame)

D) Corals feed off organisms that photosynthesize, but most don't directly utilize photosynthesis for nutrients.
