Introduction Comprehensive
Questions with Verified
Answers Graded A+
1. Describe a fact. Answer: Controlled empirical observations that are indisputable.
2. Describe a hypothesis. Answer: A statement consistenent with most of the data, must be
testable.
3. Describe a model. Answer: An explanation that appears to account for the data.
4. Describe a theory. Answer: A hypothesis that has been extensively tested by many
investigators, using ditterent approaches, widely accepted.
5. Describe a law. Answer: A theory that has been proven with outcomes that are predictable a
can be calculated.
6. What can cells do? Answer: - Grow and divide
-Have specialized functions
-Respond to stimuli
-Adapt to environmental changes

, 1. Cytology
2. Biochemistry
3. Genetics
8. Describe cytology. Answer: Cytology focuses mainly on cellular structure, and emphasizes
optical techniques.
9. Describe biochemistry. Answer: Biochemistry focuses on cellular function.
10. Describe genetis. Answer: Genetics focuses on information flow and heredity.
11. Describe the contributions of Robert Hooke. Answer: - Cytologist
-Observed compartments in cork, under a microscope, and first names cells
-Observations limited by low magnification power (30x enlargement) of his microscope
12. Describe the contributions of Antonie van Leeuwenhoek. Answer:
Produced better lenses than Hooke that magnified up to 300x.
13. What were two factors that restricted progress in early cell
biology? Answer: - Micro- scopes had limited resolution (ability to see fine detail)
-The descriptive nature of cell biology
14. Describe the descriptive nature of cell biology. Answer: Focus was
on observation, with little emphasis on explanation.
15. Describe the cell theory proposed by Schwann. Answer: 1. All
organisms consist of one or more cells
