TEST COMPLETE QUESTIONS WITH
ACCURATE SOLUTIONS
●● what is the structural and function unit of life
Answer: cell
●● Unicellular
Answer: one cell
●● Multicellular
Answer: made of many cells, more complex
●● 3 domains of life
Answer: Bacteria, Archaea, Eukarya
●● Bacteria
Answer: (microbiology) single-celled or noncellular spherical or spiral
or rod-shaped organisms lacking chlorophyll that reproduce by fission
●● Archaea
,Answer: Domain of unicellular prokaryotes that have cell walls that do
not contain peptidoglycan
●● Eukaryote
Answer: A cell that contains a nucleus and membrane bound organelles
●● Autotroph
Answer: An organism that makes its own food
●● Heterotroph
Answer: organism that obtains energy from the foods it consumes; also
called a consumer
●● binary fission
Answer: A form of asexual reproduction in single-celled organisms by
which one cell divides into two cells of the same size
●● Membrane
Answer: ALL CELLS HAVE
thin layer of tissue that covers a surface, lines a cavity, or divides a space
or organ
●● Where do archaea live?
, Answer: extreme environments
-lack oxygen, aquatic, too salty or hot for others
●● Where does bacteria live?
Answer: everywhere
●● Eukaryotic cells
Answer: Larger, complex, with nucleus, membrane bound organelles,
DNA tightly wrapped around histone proteins in chromosomes, cellulose
in plant cell walls.
●● emergent properties
Answer: New properties that arise with each step upward in the
hierarchy of life, owing to the arrangement and interactions of parts as
complexity increases.
●● ether linkage
Answer: Archaea (c o c)
●● ester linkage
Answer: bacteria and eukarya
●● Biosphere
