CHAPTER 16 Microbial Life:
Prokaryotes and Protists
questions and answers
alga (plural, algae) - answer Algae are aquatic protists containing
chlorophyll. They may be microscopic and unicellular or huge and
multicellular.
alternation of generations - answer process in which many algae
switch back and forth between haploid and diploid stages of their
life cycles
alveolates - answer Unicellular protists with subsurface cavities
(Dinoflagellates, Ciliates, and Apicomplexans).
amoeba - answer a protist that moves using flexible, cytoplasmic
extensions
amoebozoan - answer A protist in a clade that includes many
species with lobe- or tube-shaped pseudopodia.
apicomplexans - answer parasites of animals, and some cause
serious human diseases, parasitic, their apparatus at their anex
penetrates host cells, Plasmodium
Archaea - answer Domain of unicellular prokaryotes that have cell
walls that do not contain peptidoglycan
autotroph - answer plant capable of synthesizing its own food from
simple organic substances
, bacillus (plural, bacilli) - answer aerobic rod-shaped spore-
producing bacterium
Bacteria - answer single-celled organisms that lack a nucleus;
prokaryotes
biofilm - answer A surface-coating colony of one or more species of
prokaryotes that engage in metabolic cooperation.
bioremediation - answer uses bacteria to break down pollutants
brown algae - answer algae having the chlorophyll masked by brown
and yellow pigments
cellular slime molds - answer Types of slime molds that typically
exist as individual cells and reproduce with binary fission; during
stressful times, many of these cells will come together to form a
fruiting body.
chemoautotroph - answer organism that makes organic carbon
molecules from carbon dioxide using energy from chemical
reactions
chemoheterotroph - answer organism that must take in organic
molecules for both energy and carbon
chlamydia - answer a sexually transmitted infection caused by
bacteria of the genus Chlamydia see cocci
ciliates - answer a type of protozoa that moves using hairlike cilia
