Unit 3 Cells Review

Front

What is a hypertonic solution?

Back

A hypertonic solution is defined as a solution with more solute than what is inside the cell.

Front

In which direction do molecules move during diffusion?

Back

Molecules move from high concentration to low concentration.

Front

What cell part is found in plants but not in animals?

Back

Chloroplast.

Front

True or False: Water travels from high concentration to low concentration.

Back

True.

Front

What happens to a cell with a high amount of solute when placed in a hypotonic solution?

Back

It would grow larger and/or burst.

Front

Define osmosis.

Back

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

Front

What is the difference between hypertonic, hypotonic, and isotonic solutions?

Back

Hypertonic solutions have more solute than the cell, hypotonic solutions have less solute than the cell, and isotonic solutions have equal solute concentration to the cell.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy.

Front

What is the significance of the cell membrane in relation to solute concentration?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.
