Prokaryotic vs Eukaryotic Cells: Key Concepts Review

Miss Barker reviews prokaryotic and eukaryotic cells, focusing on membrane-bound organelles. Prokaryotic cells, like bacteria, lack a true nucleus and thrive in diverse environments. Eukaryotic cells, including animals and plants, have a nucleus and organelles. Both cell types share features like a cell membrane, cytoplasm, ribosomes, and DNA. The video concludes with practice questions to identify cell types.

What does it mean when an organelle is described as 'membrane-bound'?

• It has its own distinct membrane.

• It lacks a protective layer.

• It can freely float within the cell.

• It is outside the cell.
