Chapter 19, Problem 23A

Summary Introduction

To determine:

The match of the given definition with the correct vocabulary term.

Introduction:

Dinoflagellates are plantlike protists that constitute phylum Dinoflagellata. They are unicellular eukaryotes and generally considered as algae. Usually they are found in marine water but also found in freshwater habitats.

Explanation of Solution

Several members of the dinoflagellate group contain cell walls composed of thick cellulose plates that protects them. Some members of this group emit light and that’s why known as bioluminescent. Organisms that produce and emit light are called bioluminescent and the process of producing light is known as bioluminescence. Bioluminescence widely occurs in the marine organisms such as dinoflagellates, some fungi, bioluminescent bacteria, etc. Some terrestrial arthropods are also bioluminescent such as fireflies.

Conclusion

The statement, gives off light, matches with the term bioluminescent.
