chapter1: cells: the fundamentalunitsof life
unity and diversity of cells
1-1 living systems areincredibly diverseinsize, shape, environment, andbehavior. it isestimated that there are
between10million and 100 million different species. despite this wide variety of organisms, it remains difficult
to define what it means tosay something is alive. which of the following canbe describedas the smallest living
unit?
(a) dna
(b) cell
(c) organelle
(d) protein
1-2 indicate whether thefollowing statements aretrueor false. ifthestatementis false, explain why it is false.
A. the parameciumisamulticellular microorganism coveredwith hair-like cilia.
B. cells of differenttypes canhavedifferentchemical requirements.
C. the branchlike extensions thatsproutfromasingle nervecell inamammalian braincanextend over several
hundred micrometers.
1-3 for eachofthefollowing sentences, fill inthe blanks with the bestwordor phraseselectedfromthe list below. not
all words or phrases will be used;eachwordor phraseshould be usedonly once.
cells canbe verydiverse: superficially, they come in various sizes, ranging from bacterial cells suchas lactobacillus,
which is afew in length, tolarger cells suchasafrog’s egg, which hasa diameter of about one .despite the
diversity, cells resemble eachother toan astonishing degree in their chemistry. for example, the same 20 are usedto
make proteins.
similarly, thegenetic information of all cells isstoredintheir . although
