Cells exchange materials through the cell membrane Cells exchange materials through the cell membrane What does exchange mean? What does exchange mean?

Visual Vocabulary Cell Transport. Cell Membrane A protective layer that covers the cell’s surface and acts as a barrier.

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.

Cell transport 7.3. Key Questions 1.What is passive transport? 2.What is active transport?

KEY CONCEPT Cells use energy to transport materials that cannot diffuse across a membrane. 3.5 Active Transport, Endocytosis, and Exocytosis.

Cellular Transport Molecules moving across the cell membrane Cell Membrane is selectively permeable (lets some things in, some things out, but not everything)

Transport across Plasma membranes. Membranes Are differentially permeable – Permeable to SOME substances. The membrane selects what substances pass through.

CHAPTER 8.1 IN CLASS NOTES CELLULAR TRANSPORT. Ask yourself this question Fact: All things in water are dissolved  Such as Salt (NaCl) Fact: Dissolved.

Day 3.  Facilitated Diffusion – Transport of substances from high concentration to low with aid of proteins  Remember, diffusion is ALWAYS high to low.

Transport Across Membranes. The Plasma Membrane A selectively permeable phospholipid bilayer with integrated proteins.

Cellular Transport

Active and Passive Transport It is important for cells to control what enters and exits the cell. There are two main types of cell transport: __________ ____________ does not require energy. Active transport- __________________________________________ __________________________________________

Passive Transport When a cell uses no energy to move particles across a membrane _____________________ ___________________ occurs. Particles go _________________ their concentration gradient. ______________ & _______________ are passive transport. Plasma membrane Concentration gradient

Active Transport _____________________ _________________ is the movement of materials through a membrane. It goes __________________ a concentration gradient and requires energy from the cell. Plasma membrane Concentration gradient

How can I remember this? Passive Transport because you don’t need to use any energy to go down the hill…just relax! Active Transport because you use energy to go up the hill by pedaling.

Types of Active Transport _________________ is a process by which a cell surrounds and takes in material from its environment. Exocytosis ____________________________ ____________________________
