6 Which of the following is NOT a feature of all living cells? a. ribosomes b. nucleus c. DNA d. cell membrane

7 Which of the following comes closest to the size of a typical cell? a. 50 nm b. 50 m c. 50 cm d. 50 um

8 B. Cell theory 1. All living systems are made of cells (well documented, explanatory principle) Inductive reasoning

9 B. Cell theory 2. All of life’s functions are cellular

10 B. Cell theory 3. All cells come from pre-existing cells Mitosis and meiosis

11 III. Prokaryote cells Domain BacteriaDomain Archaea

12 III. Prokaryote cells calcium

13 Which of the following is NOT a tenet of the cell theory? a. all living systems are made of cells b. all physiology is cellular c. all cells come from pre-existing cells d. all cells are roughly the same size

14 What is the basic difference between prokaryotes and eukaryotes? a. prokaryotes are much smaller than eukaryotes b. prokaryotes do not have organelles c. prokaryotes do not have DNA d. prokaryotes have ribosomes; eukaryotes don’t

15 What type of logic is used predominantly in the cell theory? a. deductive b. inductive c. abductive d. constructive
