diffusion

osmosis

movement from high to low

protein pumps

endo/exo cytosis

movement from low to high

Correctly categorize the characteristics of Passive and Active Transport

Passive Transport

Active Transport

Active Transport

Passive Transport

Draw

Draw a diagram to show your understanding of Passive Transport

REQUIREMENTS:

1. Molecules in different concentrations

2. Arrow to show direction of movement

​Passive transport move substances against the concentration gradient.

Options (5)

small molecules

gas molecules (O₂ & CO₂)

small amounts of water

large molecules (glucose)

charged molecules (Na⁺, K⁺)

Determine if the molecules described can easily pass through the cell membrane or if they require a protein.

Easily Pass

Needs Protein to pass

​Small molecules easily pass

Large/Charged molecules need proteins

Draw

Correct this image so that it would show Active Transport and not Passive Transport.

Match

Correctly match the external environment to the correct cell response when placed in different Osmotic solutions.

• Cell shrinks

• Cell swells

• Cell maintains shape

External environment has higher solute

External environment has lower

External environment has equal solute

• External environment has higher solute

• External environment has lower

• External environment has equal solute
