Cell Membrane and Transport

Front

What is osmosis?

Back

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

Front

What type of transport is osmosis classified as?

Back

Osmosis is classified as Passive Transport.

Front

What organelle controls what substances may enter or leave cells?

Back

The cell membrane controls what substances may enter or leave cells.

Front

What is the direction of particle movement in Passive Transport?

Back

Particles move from high to low concentration in Passive Transport.

Front

What is the difference between Active Transport and Passive Transport?

Back

Active Transport requires energy to move substances against their concentration gradient, while Passive Transport does not require energy.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

What is the role of the cell membrane in homeostasis?

Back

The cell membrane helps maintain homeostasis by regulating the entry and exit of substances.

Front

What is a selectively permeable membrane?

Back

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

Front

What is an example of Active Transport?

Back

An example of Active Transport is the sodium-potassium pump, which moves sodium out of and potassium into the cell.

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.
