CHAPTER 1: CELLS: THE FUNDAMENTAL UNITS OF LIFE
Unity And Diversity Of Cells
1-1 Living Systems Are Incredibly Diverse In Size, Shape, Environment, And Behavior. It Is Estimated
That There Are Between 10 Million And 100 Million Different Species. Despite This Wide Variety
Of Organisms, It Remains Difficult To Define What It Means To Say Something Is Alive. Which Of
The Following Can Be Described As The Smallest Living Unit?
(a) DNA (B) Cell
(c) Organelle
(d) Protein
1-2 Indicate Whether The Following Statements Are True Or False. If The Statement Is False,
Explain Why It Is False.
A. The Paramecium Is A Multicellular Microorganism Covered With Hairlike Cilia.
B. Cells Of Different Types Can Have Different Chemical Requirements. C.
The Branchlike Extensions That Sprout From A Single Nerve Cell In A
Mammalian Brain Can Extend Over Several Hundred Micrometers.
1-3 For Each Of The Following Sentences, Fill In The Blanks With The Best Word Or Phrase Selected
From The List Below. Not All Words Or Phrases Will Be Used; Each Word Or Phrase Should Be
Used Only Once.
Cells Can Be Very Diverse: Superficially, They Come In Various Sizes, Ranging From
Bacterial Cells Such As Lactobacillus, Which Is A Few
In Length, To Larger Cells Such As A Frog’s Egg, Which Has A
Diameter Of About One .
Despite The Diversity, Cells Resemble Each Other To An Astonishing Degree In Their
Chemistry. For Example, The Same 20 Are
Used To Make Proteins. Similarly, The Genetic Information Of All Cells Is Stored In Their
. Although Contain The Same Types Of
Molecules As Cells, Their Inability To Reproduce Themselves By Their Own Efforts Means
That They Are Not Considered Living Matter.
Amino Acids Micrometer(S) Viruses
DNA Millimeter(S) Yeast
Fatty Plants
Acids Plasma Membranes
Meter
, 1-4 How Does Cellular Specialization Serve Multicellular Organisms And How
Might A High Degree Of Specialization Be Detrimental?
1-5 The Flow Of Genetic Information Is Controlled By A Series Of Biochemical
Reactions That Result In The Production Of Proteins, Each With Its Own
Specific Order Of Amino Acids. Choose The Correct Series Of Biochemical
Reactions From The Options Presented Here.
(a) Replication, Transcription, Translation
(b) Replication, Translation, Transcription
(c) Translation, Transcription, Replication
(d) Translation, Replication, Transcription
1-6 Proteins Are Important Architectural And Catalytic Components Within The
Cell, Helping To Determine Its Chemistry, Its Shape, And Its Ability To
Respond To Changes In The Environment. Remarkably, All Of The Different
Proteins In A Cell Are Made From The Same 20 . By Linking Them In
Different Sequences, The Cell Can Make Protein Molecules With Different
Conformations And Surface Chemistries, And Therefore Different Functions.
(a) Nucleotides.
(b) Sugars.
(c) Amino Acids.
(d) Fatty Acids.
1-7 Which Statement Is NOT True About Mutations?
(a) A Mutation Is A Change In The DNA That Can Generate Offspring
Less Fit For Survival Than Their Parents.
(b) A Mutation Can Be A Result Of Imperfect DNA Duplication.
(c) A Mutation Is A Result Of Sexual Reproduction.
(d) A Mutation Is A Change In The DNA That Can Generate Offspring
That Are As Fit For Survival As Their Parents Are.
1-8 Changes In DNA Sequence From One Generation To The Next May Result In
Offspring That Are Altered In Fitness Compared With Their Parents. The
Process Of Change And Selection Over The Course Of Many Generations Is The
Basis Of .
(a) Mutation.
(b) Evolution.
(c) Heredity.
(d) Reproduction.
1-9 Select The Option That Best Finishes The Following Statement:
“Evolution Is A Process .”
(a) That Can Be Understood Based On The Principles Of Mutation And Selection.
(b) That Results From Repeated Cycles Of Adaptation Over Billions Of Years.
(c) By Which All Present-Day Cells Arose From 4–5 Different Ancestral Cells.
(d) That Requires Hundreds Of Thousands Of Years.
