Unit 1 Quiz: Cell Theory.

This is a short quiz on the major ideas involved with the cell theory. It deals with important historical figures and findings, and the fundamental ideas that make up this aspect of bioogy.

Questions and Answers

1.

Who was the scientist that coined the term cell?
- A.
  
  Matthias Schleiden
- B.
  
  Robert Hooke
- C.
  
  Theodore Schwann
- D.
  
  Rudolph Virchow
- E.
  
  None of the above
Correct Answer
B. Robert Hooke

Explanation
Robert Hooke is the correct answer because he was the scientist who first coined the term "cell" in 1665. He observed thin slices of cork under a microscope and noticed small compartments that reminded him of the cells of a monastery, leading him to name them "cells." This discovery laid the foundation for the development of the cell theory, which states that all living organisms are composed of cells.

2.

Which of the following is not a major idea in the cell thoery?
- A.
  
  All cells are composed of one or more cells
- B.
  
  Cells are the basic unit of structure and organization in all living things
- C.
  
  Cells are so small that we know very little about them
- D.
  
  Cells arise only from previously existing cell and they pass genetic material to daughter cells
Correct Answer
C. Cells are so small that we know very little about them

Explanation
The given correct answer is "Cells are so small that we know very little about them." This statement is not a major idea in the cell theory because the cell theory states that all living things are made up of cells, cells are the basic unit of structure and organization, and cells arise only from previously existing cells. The size of cells is not a major idea in the cell theory.

3.

Which scientist determined that cells come from the division of other cells?
- A.
  
  Matthias Schleiden
- B.
  
  Robert Hooke
- C.
  
  Theodore Schwann
- D.
  
  Rudolph Virchow
- E.
  
  None of the above
Correct Answer
D. Rudolph Virchow

Explanation
Rudolph Virchow determined that cells come from the division of other cells. This concept, known as cell division or cell reproduction, is a fundamental principle in biology. Virchow's research and observations led to the development of the cell theory, which states that all living organisms are composed of cells and that cells arise from pre-existing cells. His work greatly contributed to our understanding of cell biology and paved the way for further advancements in the field.

4.

Which Scientist studied plant tissue and stated that all plants are made of cells?
- A.
  
  Matthais Schleiden
- B.
  
  Robert Hooke
- C.
  
  Theodore Schwann
- D.
  
  Rudolph Virchow
- E.
  
  None of the Above
Correct Answer
A. Matthais Schleiden

Explanation
Matthais Schleiden studied plant tissue and stated that all plants are made of cells. This means that he observed and conducted research on plant samples and concluded that cells are the fundamental units of all plants. Schleiden's work contributed to the development of the cell theory, which states that all living organisms are composed of cells.

5.

Which Scientist discovered that animal tissues consist of individual cells?
- A.
  
  Matthais Schleiden
- B.
  
  Robert Hookes
- C.
  
  Theodore Schwann
- D.
  
  Rudolph Virchow
- E.
  
  None of the Above
Correct Answer
C. Theodore Schwann

Explanation
The correct answer is Theodore Schwann because he was a German physiologist who, along with Matthias Schleiden, proposed the cell theory. This theory states that all living organisms are composed of cells, and Schwann specifically focused on animal tissues, discovering that they consist of individual cells. Therefore, Schwann's contribution to the cell theory makes him the scientist who discovered that animal tissues consist of individual cells.
