Exploring Levels of Organisation in Living Organisms

The video explores the levels of organization in organisms, from cells to organ systems. It explains how unicellular organisms perform all life functions within a single cell, while multicellular organisms have complex structures with specialized cells forming tissues, organs, and organ systems. The video highlights the vital organs in mammals and the organ systems that maintain body regulation. It concludes with a call to action for viewers to engage with the content.

What is the primary difference between unicellular and multicellular organisms?

• Multicellular organisms have a single cell.

• Multicellular organisms do not have specialized cells.

• Unicellular organisms have multiple cells.

• Unicellular organisms perform all life functions within one cell.
