Topic: Discovery of Cell Robert Hooke
Multiple Choice Questions
Q1. In which year did Robert Hooke observe and name "cells" while examining a thin slice of cork?
- 1663
- 1665
- 1674
- 1680
Q2. The term "cell" was coined by Robert Hooke because the compartments he observed in cork resembled the small rooms occupied by:
- Prisoners
- Monks
- Students
- Soldiers
Q3. Robert Hooke used a self-designed microscope to observe cork cells. The magnification of his microscope was approximately:
- 10x
- 30x
- 50x
- 100x
Q4. Hooke observed that the cork was composed of tiny compartments which reminded him of:
- Honeycombs in a beehive
- Rooms in a monastery
- Boxes in a warehouse
- Bricks in a wall
Q5. Which of the following statements about Hooke's observation is CORRECT?
- He observed living cells with a nucleus
- He observed dead cell walls of plant tissue
- He discovered the cell membrane
- He identified the presence of cytoplasm
Short Answer Questions
Q6. Describe the experiment conducted by Robert Hooke that led to the discovery of cells. What material did he use, and what did he observe?
Q7. Why did Robert Hooke call the structures he observed "cells"? Explain the origin of this term.
Q8. Hooke observed only the cell walls of dead cork cells. Explain why he could not observe the cytoplasm, nucleus, or other cell organelles.
Q9. Compare the microscope used by Robert Hooke with modern compound microscopes in terms of magnification and resolution.
Long Answer Questions
Q10. Discuss the contributions of Robert Hooke to cell biology. Why is his discovery considered a turning point in the history of biology, even though he only observed dead cell walls?
Q11. Imagine you are Robert Hooke in 1665. Write a diary entry describing your observation of cork cells under the microscope, your excitement, and your thoughts about what these tiny compartments might mean for understanding living organisms.
APPLICATION / ANALYSIS
Q12. A student is trying to replicate Hooke's experiment using a modern school microscope (400× magnification) and a piece of cork.
(a) What additional structures would the student observe that Hooke could not see?
(b) If the student switches to an electron microscope (200,000×), calculate how many times greater the magnification is compared to Hooke's original microscope (30×).
(c) List THREE organelles the student would observe only under the electron microscope.
Q13. Robert Hooke's discovery was published in his book "Micrographia." This book contained detailed illustrations of various microscopic observations.
(a) Why do you think detailed illustrations were important in 1665, unlike today when we have photography?
(b) If Hooke had observed onion peel instead of cork, how would his observations have differed? Explain.
