Cell structure and function I. The nature of cells
A. Basic cell features1. cell membrane 2. DNA/ RNA/ ribosomes3. protoplasm and cytoplasm
B. Cell theoryII. Prokaryote cellsIII. Eukaryotic cells
A. OrganellesB. The nucleus
1. nuclear envelope2. nucleolus3. chromosomes
C. Endoplasmic reticulum and ribosomesD. Golgi bodiesE. LysosomesF. Mitochondria and the endosymbiont theoryG. Plant cell components: chloroplasts and cell
wallsH. The cytoskeletonI. Flagella and cilia
A. Basic cell features1. plasma membrane = cell membrane =
plasmalemma2. DNA/ RNA/ ribosomes3. cytoplasm
Which of the following is NOT a feature of all living cells?
a. ribosomesb. nucleusc. DNAd. cell membrane
B. Cell theory
1. All living systems are made of cells
(well documented, explanatory principle)
Inductive reasoning
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
What type of logic is used predominantly in the cell theory?a. deductiveb. inductivec. abductived. constructive
