Back

Prokaryotes and Eukaryotes.

Front

What is a key difference between Prokaryotes and Eukaryotes?

Back

Eukaryotes have a nucleus.

Front

What does isotonic mean in terms of solute concentration?

Back

When the concentration of solutes on both sides of a membrane is the SAME.

Front

What type of transport occurs when molecules move from an area of high concentration to an area of low concentration without energy?

Back

Passive Transport.

Front

What is Facilitated Diffusion?

Back

A type of passive transport that uses protein channels to help move molecules across the membrane.

Front

What is the function of the cell membrane?

Back

To protect the cell and control what enters and exits.

Front

What is the role of ribosomes in a cell?

Back

To synthesize proteins.

Front

What is the primary function of mitochondria?

Back

To produce energy (ATP) through cellular respiration.

Front

What is the difference between hypertonic and hypotonic solutions?

Back

Hypertonic solutions have a higher concentration of solutes than the cell, while hypotonic solutions have a lower concentration.

Front

What is the process of osmosis?

Back

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