A scientist discovers a new species near coral reefs in Australia. He finds that this single-celled species is photosynthetic (using sunlight for energy), has a rigid cell wall structure with no peptidoglycan, uses a flagellum for motion, and contains a variety of internal structures that are membrane-bound. Given this information, this new species is most likely a(n) ________ cell in the ________ domain.

Question

Quizplus · Accepted Answer

The description of the new species indicates that it is photosynthetic, has a rigid cell wall with no peptidoglycan (which is a characteristic of bacteria), and has membrane-bound organelles, all of which are characteristics of eukaryotic cells. Additionally, the presence of a flagellum for motion suggests that this is likely an algal cell, which are unicellular eukaryotic organisms that are commonly found in aquatic environments like coral reefs.
