Lesson 4 Cellular Transport Quick Check! You have 5 minutes to complete it and then we will discuss.  Focus Question What processes enable substances to move into or out of a cell? Lesson objective: Understand the types of passive transport such  Passive Transport : Diffusion High concentration --> Low concentration (ink) Diffusion is the movement of particles from an area of high concentration to an area of lower concentration without the use of energy. In the image below: Diffusion causes the inks to move from high-ink concentration to low-ink concentration, until the color becomes evenly blended in the water. Lesson objective: Understand the types of passive transport such  Passive Transport : Facilitated Diffusion Water moves freely through the plasma membrane (A), but other substances cannot pass through on their own. Channel proteins (B) and carrier proteins (C) help ions and small molecules move across the membrane. Lesson objective: Understand the types of passive transport such as  Passive Transport : Osmosis (Diffusion The diffusion of of Water) water across a selectively permeable membrane is called osmosis. Before osmosis, the concentration is greater on the right side. After osmosis, the concentrations are the same on both sides of the membrane. Lesson objective: Understand the types of passive transport such  Passive Transport : Osmosis & Diffusion Lesson objective: Understand the types of passive transport such as diffusion and osmosis Water will move to the right side, since osmosis is the movement of water from high to low concentrations Lesson objective: Understand how water flows (osmosis)  STOP and Research! Take 10-15 minutes to research the following questions that will help you relate the study of cellular to our everyday life: 1) What is meant by “diffusion”? 2) What is passive transport? AND give an example. 3) Discuss facilitated diffusion and compare it to simple diffusion. 4) Find a real life example of diffusion, facilitated diffusion AND osmosis. (You can Lesson research objective: this) Understand such as diffusion and osmosis the types of passive transport 5) What is the result of osmosis?  Osmosis: Diffusion of Water isotonic solution Lesson objective: Understand the different types of solutions and  Osmosis: Diffusion of Water hypotonic solution Lesson objective: Understand the different types of solutions and  Osmosis: Diffusion of Water hypertonic solution Lesson objective: Understand the different types of solutions and Lesson objective: Understand the different types of solutions and Lesson objective: Understand the different types of solutions and water movement Answer: No, you cannot drink sea water as cells will shrink! Lesson objective: Understand the different types of solutions and water movement in plant and animal cells  In a hypotonic solution, plant cells swell but do NOT burst as they have a cell wall, Lesson objective: Understand the different types of solutions and water movement in plant and animal cells  Active Transport The movement of substances from an area of low concentration to an area of higher concentration against a concentration gradient and requires energy. Transport proteins help move substances across the plasma membrane against the normal flow. Lesson objective: Understand the process of active transport in the cell.  Active Transport Na+/K+ ATPase Pumps These pumps are found in the plasma membrane of animal cells. They maintain levels of sodium (Na+) and potassium (K+) inside and outside the cell. Lesson objective: Understand the process of active transport in the cell.  Transport of Large Particles Endocytosis is the process by which substances are taken into the cell. Exocytosis is the process by which substances are released out of the cell. Lesson objective: Understand the process of active transport in the cell. Classify the type of active transport shown in the image below. Lesson objective: Understand the process of active transport in the cell. Instruction: Please go to your google classroom and complete the Lesson Check U1-L4: Cellular Transport)!
