Question

Although they have significant differences, plants and animals are both classified in the domain Eukarya. Which of the following best describes a characteristic all Eukarya share that supports the idea they have a common ancestor?

Options:
A. Multicellularity
B. Chlorophyll production
C. Heterotrophy
D. Prokaryotic cells

Answer 1

All Eukarya share the characteristic of multicellularity which supports the idea they have a common ancestor.

Step-by-step explanation:

All Eukarya share the characteristic of 'multicellularity' which supports the idea of a common ancestor.

The domain Eukarya includes plants, animals, fungi, and protists. Eukarya is characterized by the presence of eukaryotic cells, which have a membrane-bound nucleus and organelles. Multicellularity, the ability to have multiple cells that work together, is a key characteristic shared by all organisms in the domain Eukarya.

For example, both plants and animals are multicellular. Plants have specialized cells for photosynthesis, like chloroplasts, which allow them to produce chlorophyll and carry out photosynthesis. Animals have specialized cells like nerve, muscle, and connective tissues that allow them to move and carry out specialized functions.

In summary, the characteristic of multicellularity is a shared trait among all organisms in the domain Eukarya, including plants and animals. This characteristic supports the idea of a common ancestor.
