Active vs. Passive Transport FA Learning Goal: Compare and contrast active and passive transport.

Passive vs. Active Transport. Passive Transport Does NOT require energy Moves substances from higher to lower concentration.

Transport. Concentration Gradient If there is a concentration gradient, movement will occur After concentrations are equal= dynamic equilibrium – Dynamic.

Study Tip: Make a table

Study Tip: Draw a Venn Diagram Plant vs. Animal Cells

How will the cell respond?

Movement Across a Membrane Simple Diffusion Osmosis  diffusion of WATER

Cell Membranes – What are the parts?

What can get across a membrane? Ions? Sugar? Protein? Water? Oxygen? What rules define whether something can enter/exit a cell via diffusion?

Define the terms: Diffusion Facilitated Diffusion Active Transport Give examples

Endocytosis and Exocytosis Is this active or passive transport?

Three types of Endocytosis

More questions... How big are cells? What needs to enter/exit a cell? How does it get in/out? What determines how large a cell can get? How can cells get larger and still function? Why do cells need to divide? What must cells do before dividing?
