Exploring the Differences between Animal and Prokaryotic Cells

The video tutorial explores the structure of animal cells, highlighting their organelles and nucleus, which differentiate them from prokaryotic cells. It discusses the evolution of eukaryotic cells from prokaryotic cells, a significant event in life's history. The formation of cell colonies and their role in developing multicellular organisms is also covered.

What is a key difference between animal cells and prokaryotic bacterial cells?

• Prokaryotic cells have a nucleus, while animal cells do not.

• Animal cells have a nucleus, while prokaryotic cells do not.
