Upon closer inspection you are able to determine that the individual cells are highly differentiated and organized into distinct interior and exterior tissue layers. Which of the following BEST describes the organization of this organism?
A)complex multicellular
B)simple multicellular
C)coenocytic
D)filamentous
E)eukaryotic

Question

Quizplus · Accepted Answer

The presence of multiple highly differentiated cells organized into distinct tissue layers suggests a complex multicellular organization, which is characteristic of higher-level organisms such as animals and plants. The other choices are not the best fit as coenocytic organisms consist of a single cell with multiple nuclei, filamentous organisms have elongated shapes and eukaryotic refers to the presence of a nucleus, which is universal in complex multicellular organisms. Simple multicellular organisms may have multiple cells, but they lack the level of differentiation and organization seen in complex multicellular organisms.
