Question

scientists classify all living things into three domains, and then furthered into six kingdoms as shown in the figure. analyze the figure and select the choice that accurately describes why elephants and mushrooms are in the same domain, but different kingdoms.
domains:
bacteria archaea eukarya
kingdoms:
eubacteria archaebacteria plants animals fungi protists
both were discovered by the same scientist, so they are in the same domain, but elephants are made of cells with a nucleus and mushrooms are not.
both are made of nucleated cells, so they are grouped in the same domain, but elephants can move from place to place and mushrooms cannot.
both are multicellular, so they are grouped in the same domain, but they are made of different cell types and therefore are in different kingdoms.
both are made of cells with cell walls, but elephants are much larger than mushrooms, so they are in different kingdoms.

Explanation:

• Domain Eukarya includes organisms with nucleated cells. Elephants (Animal kingdom) and mushrooms (Fungi kingdom) are both eukaryotic (nucleated cells), so they are in the same domain.
• Movement ability (elephants can move, mushrooms can't) is a key characteristic differentiating Animal and Fungi kingdoms.
• First option is wrong as cell - nucleus presence is not the error (both have nuclei). Third option: multicellularity is not the domain - defining feature (domain is about cell type - eukaryotic here). Fourth option: elephants don't have cell walls.

Answer:

Both are made of nucleated cells, so they are grouped in the same domain, but elephants can move from place to place and mushrooms cannot.
