Cell Theory and Organelles Insights

This video tutorial covers the basics of cell theory, explaining that all living things are made of cells, which are the basic unit of life. It distinguishes between prokaryotic and eukaryotic cells, highlighting their differences and common features. The tutorial also delves into the functions of various organelles within cells, emphasizing their role in protein synthesis. Additionally, it compares and contrasts the organelles found in animal and plant cells, providing a comprehensive overview of cellular structures and their functions.

Which of the following is NOT a principle of cell theory?

• All cells come from pre-existing cells.

• All cells contain a nucleus.

• Cells are the most basic unit of life.

• All living things are made of cells.
