Unit 5 Review

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What happens to a carrot placed in a hypertonic solution?

Back

The weight of the carrot decreases because water moves out of the carrot cells into the surrounding solution.

Front

What does selectively permeable mean in the context of cell membranes?

Back

Selectively permeable means that the cell membrane allows certain substances to pass through while blocking others.

Front

What is the role of stem cells in cell differentiation?

Back

Stem cells can differentiate into various types of specialized cells, playing a crucial role in development and tissue repair.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.

Front

What is the lipid bilayer?

Back

The lipid bilayer is a double layer of phospholipids that makes up the cell membrane, providing structure and protection.

Front

What is the function of the cell membrane?

Back

The cell membrane protects the cell, provides structure, and regulates the movement of substances in and out of the cell.

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 leave the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to enter the cell.

Front

What is 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.
