Cell Transport

Front

A solution is considered hypotonic to the cell if it has...

Back

A lower amount of solute compared to the cell.

Front

What is homeostasis?

Back

The maintenance of a relatively stable internal environment.

Front

Why is passive transport called 'passive'?

Back

Because it occurs WITHOUT energy.

Front

What structure on the plasma membrane is used for cell signaling and identification?

Back

Carbohydrate.

Front

What is osmosis?

Back

The diffusion of water across a membrane.

Front

What is the primary function of the plasma membrane?

Back

To protect the cell and regulate what enters and exits.

Front

Define diffusion.

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is active transport?

Back

The movement of molecules against a concentration gradient, requiring energy.

Front

What role do channel proteins play in cell transport?

Back

They facilitate the movement of specific molecules across the plasma membrane.

Front

What is the difference between hypotonic, hypertonic, and isotonic solutions?

Back

Hypotonic has lower solute concentration, hypertonic has higher solute concentration, isotonic has equal solute concentration.
