The Discovery of the Cell Review

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes (like salt) compared to another solution, causing water to move out of the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to another solution, causing water to move into the cell.

Front

What is an isotonic solution?

Back

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

Front

Which type of cells do not have a cell wall?

Back

Animal cells do not have a cell wall.

Front

What happens to red blood cells in a hypotonic solution?

Back

Red blood cells will swell and may explode due to the influx of water.

Front

What does it mean for a cell membrane to be selectively permeable?

Back

It means that the cell membrane allows certain substances to pass while blocking others.

Front

What is a phospholipid?

Back

A phospholipid is a molecule composed of a phosphate and glycerol head and two fatty acid tails, forming the basic structure of cell membranes.

Front

What is the function of the cell wall?

Back

The cell wall provides structure and protection to plant cells, fungi, and some bacteria.

Front

What is osmosis?

Back

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

Front

What is the role of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.
