Osmosis Experiment: The Journey of Water Through Membranes

The video tutorial demonstrates an experiment on osmosis using eggs. It begins with a definition of osmosis, followed by a list of materials needed for the experiment. The process involves dissolving egg shells in hydrochloric acid, handling the eggs carefully, and measuring their circumference. The eggs are then placed in salt and fresh water to observe osmosis, resulting in one egg shrinking and the other swelling. The video explains these changes through the concepts of exosmosis and endosmosis. It concludes with the role of osmosis in nature and a motivational message.

What is the process called where water molecules move through a semi-permeable membrane without energy?

• Diffusion

• Osmosis

• Active Transport

• Filtration

Which of the following materials is NOT required for the osmosis experiment?

• Sugar

• Beakers

• Hydrochloric acid

• Raw eggs

What gas is released when the eggshell reacts with hydrochloric acid?

• Carbon dioxide

• Hydrogen

• Oxygen

• Nitrogen

After removing the eggshell, what is the thin layer surrounding the egg called?

• Albumin

• Plasma membrane

• Eggshell

• Yolk

What happens to the egg placed in saltwater after a few hours?

• It dissolves

• It remains the same

• It shrinks

• It swells

Why does the egg in freshwater swell?

• Water molecules move into the egg

• Salt molecules move out of the egg

• The egg absorbs salt

• The egg releases gas

What is the term for water molecules leaving the cell?

• Diffusion

• Endosmosis

• Exosmosis

• Active transport

In the context of osmosis, what role does the egg membrane play?

• It stores water

• It provides nutrients

• It acts as a semi-permeable membrane

• It acts as a barrier

How does osmosis help root hairs in plants?

• By releasing oxygen

• By storing energy

• By absorbing minerals

• By absorbing water

What is the concentration comparison between soil water and root hair cells?

• Concentration varies randomly

• Root hair cells are more concentrated

• Both are equally concentrated

• Soil water is more concentrated
