Verified step by step guidance
1
Step 1: Understand the term 'eukaryotic.' Eukaryotic organisms have cells with a nucleus enclosed by a membrane and other membrane-bound organelles, such as mitochondria and the endoplasmic reticulum. This is distinct from prokaryotic organisms, which lack a nucleus and membrane-bound organelles.
Step 2: Review the characteristics of each kingdom listed in the options. Animalia is a kingdom that includes multicellular eukaryotic organisms, such as animals, which have complex cellular structures with a nucleus.
Step 3: Examine the other options: Bacteria and Archaea are prokaryotic organisms, meaning their cells lack a nucleus and membrane-bound organelles. Cyanobacteria are also prokaryotic and belong to the domain Bacteria.
Step 4: Compare the options to determine which kingdom includes eukaryotic organisms. Based on the definitions, Animalia is the only kingdom listed that consists of eukaryotic organisms.
Step 5: Conclude that the correct answer is Animalia, as it is the only kingdom in the options that includes organisms with eukaryotic cells.
