Review: Egg Osmosis Lab

Front

What is osmosis?

Back

Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

What happens to an egg in a hypotonic solution?

Back

The egg will gain mass as water moves into the egg.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment.

Front

What is the role of a semipermeable membrane in osmosis?

Back

A semipermeable membrane allows certain molecules, like water, to pass through while blocking others, facilitating the process of osmosis.

Front

What is the effect of placing an egg in a hypertonic solution?

Back

The egg will lose mass as water moves out of the egg into the surrounding solution.

Front

What is the significance of the egg's mass change in the osmosis lab?

Back

The change in the egg's mass indicates the movement of water in or out of the egg, demonstrating the principles of osmosis.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of solutes from an area of higher concentration to an area of lower concentration, while osmosis specifically refers to the movement of water.
