Eukaryotic cells are
A
Plant and animal cells
B
Bacterial cells
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Animal cells and plant cells are eukaryotic. Both of them contain a true nucleus and membrane-bound organelles such as mitochondria, vacuole, Golgi bodies, lysosomes, endoplasmic reticulum, etc. In addition, another membrane-bound cell organelle called chloroplast is only found in plant cells.

Detailed explanation-2: -Only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes-pro means before and kary means nucleus. Animals, plants, fungi, and protists are all eukaryotes-eu means true-and are made up of eukaryotic cells.

Detailed explanation-3: -Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Detailed explanation-4: -Prokaryotes are usually single-celled organisms, while animal and plant cells are generally multicellular. Eukaryotic cells are more complex and larger than prokaryotic cells. Animal and plant cells contain many organelles not found in prokaryotic cells.

Detailed explanation-5: -Cells of both plants and animals contain membrane-bound organelle. Plant and animals are eukaryotes, not prokaryotes.
