Exploring Cell Types and Organelles

The video tutorial explores the differences between eukaryotic and prokaryotic cells. It covers the characteristics and functions of eukaryotic cells, including their organelles like the nucleus, mitochondria, and endoplasmic reticulum. The tutorial also highlights the differences between plant and animal cells, focusing on structures like chloroplasts and cell walls. Finally, it discusses prokaryotic cells, emphasizing their lack of a nucleus and membrane-bound organelles, and compares them to eukaryotic cells.

What is the defining feature of eukaryotic cells?

• They lack DNA.

• They are always single-celled.
