Cell Transport

When particles move from areas of high concentration to areas less concentrated, this has taken place.

• diffusion
• mitosis
• endocytosis
• photosynthesis

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of

• Osmosis
• Diffusion
• Equilibrium

Which cell is placed into a hypotonic environment? 

• A
• B
• C
• D

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.

 Look at the diagram of a cross-section of a cell membrane below. The cell membrane controls movement of materials into and out of the cell. The following particles are moving from high concentration to low concentration and are using a carrier protein. How would you describe this type of movement across the membrane? 

• simple osmosis
• active transport
• simple diffusion
• facilitated diffusion
