Passive Transport. Healthy Cell 70% water 15% protein 10% fat 4% DNA and other materials 1% carbohydrate.

Structure and Function

Requires energy to move substances across the membrane. -Small & large particles.

Let’s look at one example involving osmosis. Osmosis is the diffusion of water across a semi permeable membrane such as a cell membrane. A semi permeable.

Diffusion (passive transport) Diffusion is the process by which molecules move from areas of high concentration to areas of low concentration.

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

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

Moving Cellular Material Chapter 2, Lesson 3. Membranes Control the movement of materials in and out of cell. – Semipermeable – only certain substances.

Cellular Transport: movement of materials in and out of a cell  Homeostasis: combination of two words  Homeo = same  Stasis = steady  Homeostasis:

Cell Transport Vocabulary

Cell Membrane A “thin skin” that regulates what can enter and leave the cell.

Semi - permeable Only certain substances can pass through

Passive Transport The movement of molecules across the cell membrane without the use of energy.

Diffusion The movement of molecules from areas of high concentration to areas of low concentration.

Osmosis The diffusion of water through a cell membrane

Active Transport Using energy to transport molecules across a cell membrane.

Endocytosis The process in which a cell surrounds a large particle to bring it into the cell

Exocytosis A vesicle or bubble forms around a molecule and brings it to the cell membrane to release it outside the cell

Reading Assignment Read pages Complete a venn diagram for each of the following: Diffusion –vs- Osmosis Active -vs- Passive transport Endocytosis – vs- Exocytosis Write a summary paragraph about what you read. (4 to 5 sentences)
