Moving Cellular Materials
Cell Membranes Selectively permeable Allow only some things to enter and leave.
Passive Transport Movement of material through the membrane without using energy.
Types of Passive Transport Diffusion Random movement of particles from areas of more to areas of less. Equilibrium – equal particles in each area.
Types of Passive Transport Osmosis The diffusion of water through the cell membrane. Example: Plants
Types of Passive Transport Facilitated Diffusion Movement of materials through a transport protein located in the membrane.
Active Transport Moving materials through a cell membrane with the use of energy. Requires transport proteins.
Movement of Very Large Particles Endocytosis Cell membrane surrounds the particle. Section of the membrane pinches off to form a vesicle.
Movement of Very Large Particles Exocytosis Opposite process as endocytosis. Contents of the vesicle are released outside the membrane.
Active and Passive Transport. Passive Transport Movement of substance through the cell membrane without the input of energy Three types – Diffusion –
Moving Cellular Material Chapter 2, Lesson 3. Membranes Control the movement of materials in and out of cell. – Semipermeable – only certain substances.
Cell transport is the movement of particles and it takes place because cells are trying to maintain balance (homeostasis).
Chapter 2 Lesson 3 Moving Cellular Materials. Cell Membrane The cell membrane is selectively permeable ◦ It allows certain things into the cell while.
Cellular Transport: movement of materials in and out of a cell Homeostasis: combination of two words Homeo = same Stasis = steady Homeostasis:
MOVING CELLULAR MATERIAL Chapter 10 Lesson 3. Essential Questions How do materials enter and leave cells? How does cell size affect the transport of materials?
A “thin skin” that regulates what can enter and leave the cell.
Outside of cell Inside of cell (cytoplasm) Cell membrane Proteins Protein channel Double Fat Layer Carbohydrate chains Parts of the Cell Membrane Go to.
Particles naturally travel from areas where they are crowded to areas where they are less crowded. Diffusion is the movement of particles from an area.
Cellular Transport Molecules moving across the cell membrane Cell Membrane is selectively permeable (lets some things in, some things out, but not everything)
Cells and Their Environment Objectives: 1. Relate concentration gradients, diffusion, and equilibrium. 2.Describe the importance of ion channels in passive.
Moving Cellular Materials Chapter 3 Notes. Cell Membrane Controls what moves into and out of cells. Controls what moves into and out of cells. Membrane.

Passive Transport Cells take in food, oxygen, and other substances from their environment. They also release waste material. A cell has a membrane around.
Chapter: Cell Processes Table of Contents Moving Cellular Materials.
II. Movement of Materials through Cell Membrane. Selectively permeable membrane- AAAAllows some materials to pass and not others.

Visual Vocabulary Cell Transport. Cell Membrane A protective layer that covers the cell’s surface and acts as a barrier.
Cells exchange materials through the cell membrane Cells exchange materials through the cell membrane What does exchange mean? What does exchange mean?
CELL PROCESSES What keeps them alive? Moving Cellular Materials Cells have a _____ membrane that regulates what goes into or out of the cell. Passive.
Chapter 4 Cells and Their Environment Section 1: Passive Transport Section 2: Active Transport.
Passive and Active Transport Movement of material into and out of cells.
Cellular Structure and Function Animal Cell Plant Cell Plant and Animal Cell Structures 7.3 Structures and Organelles Chapter 7.
Cell Membrane Also known as the Plasma Membrane Surrounds the cell.
Passive vs Active Transport Osmosis, Diffusion, and Energy.
Transport through Cell Membranes. Cell Transport Cells use several methods of moving substances across the cell membrane. Sometimes they must acquire.
* GPS: S7L2 Students will describe the structure and function of cells, tissues, organs, and organ systems. a. Explain that cells take in nutrients in.
Maintaining Cellular Homeostasis How do organisms regulate their body’s internal environment?
Plasma Membrane Thin, flexible boundary between the cell and its environment The Plasma Membrane Cellular Structure and Function Allows nutrients.

Passive vs. Active Transport. Passive Transport Does NOT require energy Moves substances from higher to lower concentration.
Chapter 4 – The Cell In Action. What do you think? 1. How do water, food, and wastes get into and out of a cell 2. How do cells use food molecules? 3.
Moving Cellular Materials Pg Passive Transport A cell’s membrane is semi permeable or selectively permeable which means it allows some things.
Diffusion & Osmosis Diffusion: Movement of solute from an area of high concentration to low concentration Osmosis: Diffusion of water.
Transport. Concentration Gradient If there is a concentration gradient, movement will occur After concentrations are equal= dynamic equilibrium – Dynamic.
The Cell and its Environment: The processes behind the movement of substances in and out of cells.
Diffusion and Osmosis. Importance of Water Living things are composed of more than 50 percent water and depend on water to survive. Living things are.
Discussion Questions – in your notes 1. Movement across a cell membrane without the input of energy is described by what term? 2. A substance moves from.
