Prince Charles visits Fitzalan High School in Cardiff

The video tutorial explores how water moves in and out of plant cells through practical experiments. Students conduct activities involving potato cylinders and sodium chloride solutions to measure mass changes. The results and observations are discussed, highlighting different cell types and the effects of varying sodium concentrations.

What is the main topic the teacher introduces in the lesson?

• The structure of plant cells

• How water moves in and out of plant cells

• The process of photosynthesis

• The lifecycle of a plant

What are the students measuring in their experiment with potato cylinders?

• The color change of the potatoes

• The growth rate of the potatoes

• The mass of the potatoes before and after soaking

• The temperature of the water

What substance are the potato cylinders soaked in during the experiment?

• Sodium chloride solution

• Vinegar

• Distilled water

• Sugar solution

What does an increase in mass of the potato cylinders indicate?

• Water has moved out of the cells

• The cells have become dehydrated

• The cells have shrunk

• Water has moved into the cells

What is the significance of different concentrations of sodium chloride in the experiment?

• To change the color of the potato cylinders

• To measure the speed of chemical reactions

• To observe how different concentrations affect water movement

• To test the effect of temperature on osmosis
