Cellular Transport

What does “high concentration area” mean?

• Spread out
• Tightly packed together
• Uncrowded
• Spacious

Why are diffusion and osmosis important to cells?

• It allows them to take in materials/substances without using energy.

• It allows them to reproduce.

• It allows them to absorb sunlight.

• It allows cells to use all energy.

What does selectively-permeable mean?

• Allow certain things to enter and leave 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.
