Question

types of cells prokaryotic cells eukaryotic cells domains domain bacteria domain archaea domain eukarya earliest cells 1. how many domains are there in this system of classification? 2. how many kingdoms are there in this system of classification? 3. which domain do plant and animals belong to? 4. what type of cells compose plant and animal cells? 5. what type of cells compose bacteria and archaea? 6. evaluate the following claim: “prokaryotic cells are always single - celled and eukaryotic cells are always multicellular.” use evidence from the diagram to support your answer.

Explanation:

Step1: Count domains

From the diagram, we see Domain Bacteria, Domain Archaea, and Domain Eukarya. So there are 3 domains.

Step2: Diagram doesn't show kingdoms

The diagram only shows domains and cell - types, not kingdoms. So we can't answer this from the given diagram.

Step3: Identify domain for plants and animals

Plants and animals belong to Domain Eukarya.

Step4: Determine cell - type for plants and animals

Plant and animal cells are eukaryotic cells.

Step5: Determine cell - type for bacteria and archaea

Bacteria and archaea are composed of prokaryotic cells.

Step6: Evaluate the claim

The claim is false. The diagram doesn't specify multicellularity or unicellularity, but we know there are single - celled eukaryotes (like amoebas) and some prokaryotes can form colonies.

Answer:

1. 3
2. Can't be determined from the diagram
3. Domain Eukarya
4. Eukaryotic cells
5. Prokaryotic cells
6. False. There are single - celled eukaryotes and some prokaryotes can form colonies.
