Cell Transport

A balance that an organism maintains by regulating what goes into and out of the cell.

• Homeostasis
• Plasmolysis
• Hypotonic

The diffusion of water across a selectively permeable membrane is called 

• active transport
• facilitated diffusion
• osmosis
• phagocytosis

Movement of particles from high to low concentration.

• Passive Transport

• Active Transport

Osmosis is a form of ______________. 

• Passive Transport
• Active Transport

What does selectively-permeable mean?

• The cell controls what passes in and out of the cell
• Nothing gets through
• The cell lets only large substances through

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.

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

What is diffusion?

• Molecules move randomly

• Molecules do not move

• Molecules move from high to low concentration

• Molecules move from low to high concentration

What is active transport?

• Molecules move randomly

• Molecules do not move

• Molecules move from high to low concentration

• Molecules move from low to high concentration
