Cell Transport and Organelles Concepts

This video tutorial covers the basics of cell theory, highlighting the contributions of key scientists and the fundamental principles that all living organisms are made of cells. It explains the differences between prokaryotic and eukaryotic cells, and further distinguishes between plant and animal cells. The tutorial also delves into the mechanisms of transport across cell membranes, including active and passive transport, and the role of osmosis.

Which of the following statements is NOT part of the cell theory?

• All cells come from pre-existing cells.

• Cells can spontaneously generate from non-living material.

• Cells are the basic unit of structure and function in living things.

• All living organisms are made up of cells.

What is a key difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have more organelles than eukaryotic cells.
