Chapter 8.3 - Cell Transport

• Passive vs Active Transport

• Diffusion vs Osmosis

• Hypertonic, Hypotonic, Isotonic

Multiple Choice

Passive Transport is the movement of particles across the membrane from an area of [ ___ ] to an area of [ ___ ]

• low to high

• low to low

• high to low

• high to high

Multiple Choice

What is diffusion?

• when molecules move from a low concentration to a high concentration

• when molecules move from a high concentration to a low concentration.

• no movement

• molecules move everywhere

Multiple Choice

Diffusion & Facilitated Diffusion are both __________ transport.

• passive

• active

• easy

• free

Multiple Choice

Which diagram best shows the end result of diffusion?

• F

• G

• H

• J

Multiple Choice

Why is diffusion so important in biology?

• It's the basic power source for most types of cells

• It prevents toxins from entering our bodies

• It allows substances to move across cell membranes

• Without diffusion, cell division could not take place

Multiple Choice

Osmosis is:

• diffusion of water molecules through a semi-permeable membrane from an area of low concentration to an area of high concentration

• the diffusion of particles from an area of high concentration to an area of low concentration

• the diffusion of particles from an area of low concentration to an area of high concentration

• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration

Multiple Choice

Osmosis is the movement of _____ across a membrane.

• food

• oxygen

• water

• energy

Multiple Choice

Which way will the water molecules move during osmosis?

• OUT of the cell so the cell shrinks

• OUT of the cell so the cell swells

• INTO the cell so the cell shrinks

• INTO the cell so the cell swells

Multiple Choice

Which type of transport requires an input of energy?
