4
Which of the following does NOT show an evolutionary link between green algae and land plants?
Both have cellulose cell walls
Both store food energy as starch
Both are rooted
Both possess chlorophyll a and b
5
What was the product of endosymbiosis?
Photosynthesizing plants
Unicellular eukaryotes
Multicellular eukaryotic organisms
Free-living prokaryotes
6
A branching diagram showing the inferred evolutionary relationships between organisms is...
Phylogenetic Tree
Evolutionary Tree
Tree of Life
Family Tree
7
Which is NOT a reason that terrestrial plants are thought to evolve from green algae?
Both possess vascular tissue
Both possess chlorophyll a and b
Both store food energy as starch
Both have cellulose cell walls
8
Which phylum has organisms with an exoskeleton (...bones outside body)?
Arthropod
Archeabacteria
Vertebrate
Chordata
9
Why do bacteria undergo conjugation?
To initiate the process to convert to an eukaryotic cell
To avoid threats to survival by going dormant
To make new genetic combinations to adapt to new conditions
To create two identical but smaller new cells
10
A zygote is a cell that is ...
Gamete
Diploid
Sex Cell
Haploid
11
Phylogenetic Species Concept is based on....
Structural function of organisms
Ability of organisms to interbreed
Evolutionary history of organisms
Body shape of organisms
12
In which part of the viral replication cycle does a Provirus form?
Lysogenic
Prion
Capsid
Lytic
13
What is a species?
Named group of organisms
Set of organisms that can breed producing fertile offspring
Organisms that capture sunlight to produce energy
Study of evolutionary history of organisms
14
What statement about a virus is true?
Do not cause diseases
Contain membrane-bound organelles
Only contain RNA
Cannot replicate independently
15
The land is moist. What life stage of a seedless, non-vascular plant is likely longer?
Neither -- Life stages are always equal in length
Sporophyte (Dipoid)
Embryonic
Gametophyte (Haploid)
16
Kingdom characteristics are uni-celluar or multicellular, and asexual or sexual reproduction
Plantae
Protista
Fungi
Animalia
17
Which of the following is NOT multicellular Protista algae?
Green
Brown
Green-Blue
Red
18
In which environment would you likely find an acidophile?
Volcano
Your stomach
Deep Sea Vent
Ice Sheet
19
Individual slime moulds can join together to move, This does not make them animal-like. Why?
Other classes of life can also move (e.g., flagella)
Slime moulds are prokaryotic
Classification is based on means to obtain nutrients
Animals must have the ability to move as an individual
20
Eukaryote cells evolving from a symbiotic relationship of two or more prokaryote cells is...
Evolution
Mutation
Endosymbiosis
Mutualism
21

In the viral DNA
In the virus capsid
22
What relationship showed fungi are more closely related to animals than plants?
Physiological
Taxonomical
DNA
Anatomical
23
Which two organisms are most closely related
Same Class but different Order
Same Family but different Genus
Same Genus but different Species
Same Phylum but different Class
24
Which is NOT a plant adaptation for life on land?
Means to keep the plant from drying out
System to transport water throughout the plant
Means to photosynthesize
System to support the plant
25
Type of asexual reproduction when a cell divides into two genetically identical cells
Conjugation
Budding
Binary fission
Fragmentation
26
Which is NOT a shape of an Eubacteria?
Square
Cocci
Spiral
Rod
