Passive Transport

Front

What is osmosis?

Back

Osmosis is the movement of water across a membrane.

Front

Define osmosis in detail.

Back

Osmosis is the diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration.

Front

What does Passive Transport mean?

Back

Passive Transport means no energy is used.

Front

What is Selective Permeability?

Back

Selective Permeability is the ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

In which organisms can diffusion occur?

Back

Diffusion can occur in both plants and animals.

Front

What is the main characteristic of passive transport?

Back

The main characteristic of passive transport is that it does not require energy.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of particles from high to low concentration, while osmosis specifically refers to the movement of water.

Front

What type of molecules can pass through a semi-permeable membrane during osmosis?

Back

Water molecules can pass through a semi-permeable membrane during osmosis.

Front

What is the role of a semi-permeable membrane in osmosis?

Back

A semi-permeable membrane allows certain molecules, like water, to pass through while blocking others.

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.
