Cell Transport, Membranes, Osmosis, and Diffusion

Front

What are two types of passive transport?

Back

Osmosis and diffusion are two types of passive transport that do not require energy.

Front

Which part of a phospholipid is hydrophobic?

Back

The fatty lipid tails of a phospholipid are hydrophobic.

Front

What does hydrophilic mean?

Back

Hydrophilic means water-loving.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to another solution.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as another solution.

Front

What is active transport?

Back

Active transport is the movement of molecules against their concentration gradient, requiring energy.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.
