MULTIPLE tCHOICE
1. A tstudent tis tobserving ta tcell tunder tthe tmicroscope. tIt tis tobserved tto thave
tsupercoiled tDNAwith thistones. tWhich tof tthe tfollowing twould talso tbe tobserved tby
tthe tstudent?
a. A tsingle tcircular tchromosome
b. A tnucleus
c. Free-floating tnuclear tmaterial
d. No torganelles
ANS: t B
The tcell tdescribed tis ta teukaryotic tcell, tso tit thas thistones tand ta tsupercoiled tDNA
twithin titsnucleus; tthus, tthe tnucleus tshould tbe tobserved. tA tsingle tcircular
tchromosome tcalled ta tprokaryote tcontains tfree-floating tnuclear tmaterial tbut thas
tno torganelles.

2. A tnurse tis tinstructing tthe tstaff tabout tcellular tfunctions. tWhich tcellular tfunction tis
tthe tnurse tdescribing twhen tan tisolated tcell tabsorbs toxygen tand tuses tit tto ttransform
tnutrients tto tenergy?
, a. Metabolic tabsorption
b. Communication
c. Secretion
d. Respiration
ANS: t D
The tcell’s tability tto tabsorb toxygen tis treferred tto tas trespiration twhile tits
communication tabilityinvolves tmaintenance tof ta tsteady tdynamic tstate, tmetabolic
t
absorption tprovides tnutrition, tand tsecretion tallows tfor tthe tsynthesizing tof tnew
t
substances.
