Unit 3: Cell Transport Remediation Assignment

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What type of transport is diffusion?

Back

Diffusion is a form of passive transport, meaning it does not require energy to occur.

Front

What role do proteins play in the phospholipid bilayer?

Back

Proteins embedded in the phospholipid bilayer form channels that allow larger molecules to pass through the cell membrane.

Front

In which direction do solutes move during passive transport?

Back

Solutes move from an area of higher concentration to an area of lower concentration without the use of energy.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

Define active transport.

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is the difference between isotonic and hypertonic solutions?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, while a hypertonic solution has a higher concentration of solutes.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water enters the cell, causing it to swell and potentially burst.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses proteins to help move molecules across the cell membrane.
