UA BSC-109 Exam 1-- Kleinhuizen
Questions And Correct Answers
Be able to describe the 4-stage hypothesis for the origin of life - answer Synthesis of
organic compounds, abiotic synthesis of polymers, formation of pre cells, origin of self
replication
Know what prokaryotes are and how they differ from eukaryotes - answer Prokaryotes
are unicellular organisms that are divided into bacteria and archaea, eukaryotes are
unicellular and multicellular and have different cell structures
know what a biofilm is and how it can impact humans - answer biofilms are a cluster of
prokaryotic cells
know how prokaryotes reproduce - answer binary fission (copying DNA and dividing
rapidly)
describe an endospore - answer specialized cell with thick walls that protects a
prokaryote from unfavorable conditions
be able to define the 4 main modes of nutrition in prokaryotes - answer
photoautotrophs-->(use photosynthesis)
chemoautotrophs--> inorganic compounds
photoheterotrophs --> photosynthesize and consume organic compounds from carbon
chemoheterotrophs--> consume organic compounds
familiar with some of the major roles that prokaryotes play in our ecosystem - answer
aide in digestion, decompose dead matter, recycle chemicals, remove pollutants from
water and air
Know 2 main groups of prokaryotes and the basics of how they differ - answer bacteria-
everywhere and most abundant; used in antibiotics and ecosystem cycles
Archaea- extreme environments
understand how bacteria causes disease - answer weakened immune system allows
pathogens to enter the body
know how protists differ from prokaryotes and from other eukaryotes - answer protists
with the first to evolve from prokaryotes and is any eukaryote that isn't a plant, animal,
or fungus
know the 4 major types of protists - answer protozoans
, slime molds
algae
seaweeds
review the common diseases caued by protists - answer parasites, salmonella
understand the differences between algae and seaweed - answer algae uses
photosynthesis to support aquatic food chains, seaweeds are large multicellular algae
and are classified based on color
be familiar with endosymbiosis - answer relationship in which one organism lives inside
of a host
be able to describe some ways in which plant structures and reproduction have been
adapted for life on land - answer structural- cuticle, roots, shoots, leaves, vascular
tissue
reproduction- gametes, effs, sperms (spores, fruits, flowers)
know what mycorrhizae are - answer fungi that attatch to roots in symbiosis to help
retain water in the plant; gets nutrients in exchange
be able to list the 4 major groups of plants - answer bryophytes
ferns
gymnosperms
angiosperms
review the order of origination of the 4 major groups of plants - answer bryophytes,
ferns, gymnosperms, angiosperms
know how the 4 major groups of plants differ from each other and know examples of
each - answer bryophytes- lack true roots, leaves, and lignin, needs water to reproduce
ferns- seedless vascular plants, requires water for fertilization
gymnosperms- seeds in specialized chambers, conifers (pines and firs)
angiosperms- flowering plants with stamen and carpel
describe the process of alternation of genetics in plants in detail - answer cycle of some
plants and algae in which generations alternate between hapliod and diploid organisms
know what a fruit is and the purpose of a fruit for a plant - answer fruit protects seeds
