Biology Cambridge IGCSE Course – Code 0610 and 0970: Topic 3 – Movement In and Out Of Cells

Course Description:

Welcome to our Biology Cambridge IGCSE course, meticulously tailored to help you conquer the intricacies of Topic 3: Movement In and Out Of Cells. This comprehensive course is specifically designed for both Code 0610 and Code 0970 syllabi, ensuring you’re well-prepared for the IGCSE Biology examination.

Course Highlights:

  • Comprehensive Core and Supplement Objectives: Master all core and supplement objectives as outlined in the syllabus for theory (papers 1, 2, 3, 4). These objectives provide a solid foundation for exam success.
  • Thoroughly Explained Experiments: Gain a deep understanding of practical experiments with detailed explanations. Notes summarize the method, results, interpretation, evaluation, reliability, and conclusion, enabling you to excel in paper 6 questions.

Course Outline & Objectives (Core and Supplement):

  1. Diffusion (Lesson 1): Key objectives include:
    • Describe diffusion as the net movement of particles from a region of their higher concentration to a region of their lower concentration (i.e. down a concentration gradient), as a result of their random movement
    • State that the energy for diffusion comes from the kinetic energy of random movement of molecules and ions
    • State that some substances move into and out of cells by diffusion through the cell membrane.
    • Describe the importance of diffusion of gases and solutes in living organisms.
  1. Osmosis (Lesson 2): Key objectives include:
    • Describe the role of water as a solvent in organisms with reference to digestion, excretion, and transport.
    • State that water diffuses through partially permeable membranes by osmosis.
    • State that water moves into and out of cells by osmosis through the cell membrane.
    • State that plants are supported by the pressure of water inside the cells pressing outwards on the cell wall.
    • Describe osmosis as the net movement of water molecules from a region of higher water potential (dilute solution) to a region of lower water potential (concentrated solution), through a partially permeable membrane.
    • Explain the effects on plant cells of immersing them in solutions of different concentrations by using the terms: turgid, turgor pressure, plasmolysis, flaccid.
    • Explain the importance of water potential and osmosis in the uptake and loss of water by organisms.
  2. Active Transport (Lesson 3): Key Objectives include:
    • Describe active transport as the movement of particles through a cell membrane from a region of lower concentration to a region of higher concentration (i.e., against a concentration gradient), using energy from respiration.
    • Explain the importance of active transport as a process for the movement of molecules or ions across membranes, including ion uptake by root hairs.
    • State that protein carriers move molecules or ions across a membrane during active transport.
  1. Experiment – Diffusion and Surface Area (Lesson 4): Key Objectives include:
    • To investigate the effect of surface area to volume ratio on diffusion.
  2. Experiment – Diffusion and Temperature (Lesson 5): Key Objectives include:
    • To investigate the effect of temperature on diffusion.
  3. Experiment – Diffusion and Distance (Lesson 6): Key Objectives include:
    • To investigate the effect of distance on diffusion.
  4. Experiment – Osmosis and Water Flow (Lesson 7): Key Objectives include:
    • To demonstrate the effect of osmosis using Visking tubing.
  5. Experiment – Plasmolysis (Lesson 8): Key Objectives include:
    • To observe plasmolysis in plant cells.
  6. Experiment – Osmosis and Turgor (Lesson 9): Key Objectives include:
    • To model turgor in a plant cell using partially permeable Visking dialysis tubing.
  7. Experiment – The Effects of Varying the Concentration of Salt Solution on Potato Tissue (Lesson 10): Key Objectives include:
    • To Investigate the effects on plant tissues of immersing them in solutions of different concentrations.

Course Benefits:

  • Engage with meticulously crafted video lessons, providing comprehensive explanations of each lesson and experiment.
  • Access downloadable summary study sheets that condense essential information, aiding your pursuit of an A* grade.
  • Enhance your preparation with quizzes and assignments based on past papers to boost your confidence for the exam.
