Which of the following is NOT one of the three parts of the cell theory?

• All living things are composed of one or more cells.

• Cells are the basic unit of structure and function in living things.

• All cells have a nucleus.

• All cells arise from pre-existing cells.

Compare and contrast eukaryotic and prokaryotic cells. Which of the following statements is true?

• Eukaryotic cells have a nucleus, while prokaryotic cells do not.

• Both eukaryotic and prokaryotic cells have a nucleus.

• Prokaryotic cells are generally larger than eukaryotic cells.

• Eukaryotic cells do not have membrane-bound organelles, while prokaryotic cells do.

Explain how the invention of the microscope contributed to the development of cell theory. Which of the following best describes this contribution?

• The microscope allowed scientists to see cells for the first time, leading to the discovery that all living things are made of cells.

• The microscope was used to create detailed drawings of cells, which proved that cells are the basic unit of life.

• The microscope helped scientists to see the DNA inside cells, proving that all cells arise from pre-existing cells.

• The microscope was used to measure the size of cells, showing that all cells are the same size.

Consider the contributions of Matthias Schleiden and Theodor Schwann to cell theory. How did their work collectively advance the understanding of cell biology?

• Schleiden discovered that all plants are made of cells, while Schwann discovered that all animals are made of cells, leading to the conclusion that all living things are composed of cells.

• Schleiden and Schwann both discovered that cells can spontaneously generate from non-living matter.

• Schleiden and Schwann worked together to invent the first microscope, which allowed them to see cells.

• Schleiden and Schwann proved that cells are the basic unit of heredity.

The Cell Theory:

1. 1. All living organisms are composed of one or more ​ (a)   . (Unicellular or Multicellular)

2. 2. All cells arise from ​ (b)   cells. (Not from Spontaneous Generation)

3. 3. Cells are the structural and functional unit of ​ (c)   . (Nothing living smaller than a Cell)

• cells
• preexisting
• life
