Biology Unit 3 Part 1 (For Final Review)

Front

What is the rigid layer that lies outside the plasma membrane in plant cells?

Back

Cell wall - it provides structure and protection.

Front

What happens to water in a hypertonic solution?

Back

Water will move out of the cell.

Front

What is the result of diffusion across a semi-permeable membrane?

Back

Equal concentrations on both sides of the semi-permeable membrane.

Front

What type of transport involves moving substances against their concentration gradient?

Back

Active Transport Pump.

Front

What type of cell contains a nucleus?

Back

Eukaryotic cell.

Front

What is the function of the cell membrane?

Back

It regulates what enters and leaves the cell.

Front

Define osmosis.

Back

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

Front

What is facilitated diffusion?

Back

A process that allows substances to cross membranes with the assistance of special proteins.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus; eukaryotic cells do.

Front

What is a semi-permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.
