NYS Diffusion Part 1

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration until they are evenly distributed.

Front

What regulates what enters and leaves a cell?

Back

The Cell Membrane regulates what enters and leaves a cell.

Front

What is an example of diffusion?

Back

An example of diffusion is the smell of perfume spreading in a room.

Front

What happens to the cell membrane during osmosis?

Back

The cell membrane can shrink or swell depending on the concentration of the surrounding solution.

Front

Why can't we drink saltwater?

Back

Drinking saltwater dehydrates us because it causes water to leave our cells.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion involves the movement of solute molecules, while osmosis specifically refers to the movement of water molecules.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is the same inside and outside the cell, resulting in no net movement of water.

Front

What is active transport?

Back

Active transport is the process of moving molecules across a cell membrane against their concentration gradient, requiring energy.

Front

What happens to plant cells in a hypertonic solution?

Back

In a hypertonic solution, plant cells lose water, causing the cell membrane to shrink away from the cell wall.
