Cell Transport

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy.

Front

What is required for active transport?

Back

Active transport requires energy to move substances against their concentration gradient.

Front

What is osmosis?

Back

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

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain substances to pass while blocking others.

Front

What is diffusion?

Back

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

What is the end result of diffusion?

Back

The end result of diffusion is an equal distribution of particles in a space.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances.

Front

What occurs when a gummy bear is placed in salt water?

Back

The gummy bear loses water through osmosis, causing it to decrease in mass.

What is the role of energy in active transport?

Back

Energy is used in active transport to move substances against their concentration gradient.
