Practice Questions

Test your understanding with targeted questions

Question 1 Easy

State the three main parts of the Cell Theory.

  • Answer: 1) All living things are made of cells. 2) The cell is the basic unit of structure and function. 3) All cells come from pre-existing cells.
  • Hint: Think about what life is made of, how it works, and where it comes from.

💡 Hint: Think about what life is made of, how it works, and where it comes from.

Question 2 Easy

Which scientist first used the term "cell" after looking at a slice of cork?

  • Answer: Robert Hooke.
  • Hint: He thought the small boxes looked like rooms in a monastery.

Question 1

Which of the following is NOT a part of the Cell Theory?

  • Type: mcq
  • Options: A) All cells come from pre-existing cells, B) All cells have a nucleus, C) The cell is the basic unit of life, D) All living things are made of cells.
  • Correct Answer: B
  • Explanation: While many cells have a nucleus (eukaryotes), prokaryotic cells (like bacteria) do not. Therefore, having a nucleus is not a requirement for all cells under the general theory.
  • Hint: Remember the difference between Prokaryotes and Eukaryotes.

Question 2

True or False: Anton van Leeuwenhoek was the first person to observe living, moving cells under a microscope.

  • Type: boolean
  • Options: True, False
  • Correct Answer: True
  • Explanation: While Hooke saw dead cork cells, Leeuwenhoek observed living microorganisms in pond water and called them "animalcules."
  • Hint: He is often called the "Father of Microbiology."

Challenge 1 Hard

The Spontaneous Generation Mystery: Imagine you are a scientist in the 1700s. People believe that mice are "born" from piles of dirty rags and wheat. Which part of the Cell Theory would you use to argue against this, and what evidence would you need?

  • Solution: I would use the third part: "All cells arise from pre-existing cells." To prove it, I would need to show that mice only appear if parent mice are present to reproduce, and that life cannot simply "form" from rags.
  • Hint: Think about Rudolf Virchow’s contribution.

💡 Hint: Think about Rudolf Virchow’s contribution.

Challenge 2 Hard

Medical Impact: How does the Cell Theory help doctors treat a disease like cancer?

  • Solution: Since the theory states that all cells come from pre-existing cells, doctors understand that cancer is a result of uncontrolled cell division. Treatment focuses on stopping those specific cells from dividing and spreading.
  • Hint: If cells didn't come from other cells, we couldn't track how a disease grows.

💡 Hint: If cells didn't come from other cells, we couldn't track how a disease grows.
