Exploring Cells to Systems: Learn Functions and Structures

Dive into the world of cells and systems, understanding their functions and structures, from mitochondria to the circulatory system. Discover the importance of organelles like the nucleus and chloroplast for cell functions, and explore how circulation and microscopy have advanced science and medicine. Learn about essential concepts like tissues, organ systems, and the respiratory system. Uncover how microscopes revolutionized our understanding of cells and their functions, and the significant role of the circulatory system in maintaining health.

  1. Grade 8 Review Cells to Systems

  2. Cell Parts • Q1: What is the function of the mitochondria?

  3. Cell Parts • A1: the function of the mitochondria is to create energy for the cell.

  4. Cell Parts • Q2: What is the function of the nucleus?

  5. Cell Parts • A2: The nucleus is the control centre of the cell.

  6. Cell Parts • Q3: What two extra organelles are found in plants only?

  7. Cell Parts • A3: Chloroplasts and Cell Wall

  8. Cell Parts • Q4: What is the function of the chloroplast?

  9. Cell Parts • A4: The function of the chloroplast is to create food from light – PHOTOSYNTESIS.

  10. Cell Parts • Q5: What is the function of the cell membrane?

  11. Cell Parts • A5: - controls the movement of substances in and out. • Provides protection (keeps foreign bodies out) • Holds the cell together - shape

  12. Cell Parts • Q6: What is the following organelle?

  13. Cell Parts • A6: Golgi Apparatus

  14. Circulation • Q7: What prevents blood from moving backwards in the heart and veins?

  15. Circulation • A7: Valves

  16. Circulation • Q8: What is the largest artery in the body?

  17. Circulation • A8: The Aorta

  18. Circulation • Q9: What molecule in the blood makes the blood red when combined with oxygen?

  19. Circulation • A9: Hemoglobin.

  20. Circulation • Q10: What are 2 waste products of respiration?

  21. Circulation • A10: Water and Carbon Dioxide

  22. Circulation • Q11: Approximately how many times does an average person’s heart beat while resting?

  23. Circulation • A11: 70-75 bpm

  24. Circulation • Q12: What is the large vein from the top of the body that enters the right atrium called?

  25. Circulation • A12: Superior Vena Cava.
