B. Cell theory

1. All living systems are made of cells

(well documented, explanatory principle)

Inductive reasoning

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

cellular

B. Cell theory3. All cells come from pre-existing cells

Mitosis and meiosis

Which of the following is NOT a tenet of the cell theory?a. all living systems are made of cellsb. all physiology is cellularc. all cells come from pre-existing cellsd. all cells are roughly the same size

What is the basic difference between prokaryotes and eukaryotes?

a. prokaryotes are much smaller than eukaryotesb. prokaryotes do not have organellesc. prokaryotes do not have DNAd. prokaryotes have ribosomes; eukaryotes don’t
