Front

What are the two parts of a phospholipid?

Back

Hydrophilic heads and hydrophobic tails.

Front

What is the main difference between prokaryotic and eukaryotic cells?

What direction do molecules move during simple diffusion?

Back

From high to low concentrations.

Front

What is exocytosis?

What is the function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

Define osmosis.

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy, while passive transport does not.

Front

What is a vesicle?

Back

A small membrane-bound sac that transports substances within a cell.
