IRSC MCB2010 EXAM 1 (ACTUAL 2025/2026)
QUESTIONS & VERIFIED ANSWERS
classifications of microbes - (answers)bacteria, archaea, fungi, protozoa, algae,
and small multicellular animals
bacteria & archaea - (answers)prokaryotes, unicellular & lack nucleus, much
smaller than eukaryotes, found in moist environments & isolated extreme
conditions, asexual repro, bacteria has peptidoglycan cell wall while archaea does
not
2 types of prokaryotes - (answers)bacteria and archaea
fungi - (answers)eukaryotic (membrane bound nucleus), obtain food from other
organisms, possess cell walls, and include: molds (multicellular; grow as long
filaments; repro by sexual and asexual spores) & yeasts (unicellular; repro
asexually by budding and some produce sexual spores)
molds - (answers)fungi; multicellular; grow as long filaments; repro by asexual and
sexual spores
yeasts - (answers)fungi; unicellular; repro asexually by budding and some produce
sexual spores
protozoa - (answers)single-celled eukaryotes that lack a cell wall and are similar to
animals in their nutritional needs and structure, mostly asexual repro but some
sexual, locomotion by pseudopods, cilia, and flagella
, 2|Page
pseudopods - (answers)false feet, means of locomotion, flow in direction of travel
cila - (answers)numerous short protrusions that propel organism
flagella - (answers)extension of cell that are fewer, longer, and more whiplike
than cilia
algae - (answers)unicellular or multicellular, photosynthetic, simple repro
structures, categorized on basis of pigmentation and composition of cell wall
other organisms of importance - (answers)parasites and viruses
three processes scientists thought living things arose from - (answers)asexual,
sexual, and non living matter
who proposed that living things could arise from non living matter -
(answers)aristotle
redi's experiments - (answers)allowed people to doubt aristotles theory because
when decaying meat kept from flies no maggots developed
