BIOL 204 LECTURE EXAM 2
CERTIFICATION REVIEW SET 2026
ANSWERS GUARANTEED PASS
⫸ eukaryote Answer: A cell that contains a nucleus and membrane
bound organelles
⫸ nucleoid Answer: A non-membrane-bounded region in a prokaryotic
cell where the DNA is concentrated.
⫸ nucleus Answer: A part of the cell containing DNA and RNA and
responsible for growth and reproduction
⫸ prokaryote Answer: A unicellular organism that lacks a nucleus and
membrane bound organelles
⫸ amyloplast Answer: Unpigmented plasids that store starch grains,
abundent in cells of stems, tubers, and seeds
⫸ anchoring junction Answer: mechanically attaches adjacent cells to
each other or to the basement membrane
,⫸ bacterial flagellum Answer: A ropelike structure built from actin
proteins that, through rotary movements, propels a bacterium through
fluid.
⫸ capsule Answer: A sticky layer that surrounds the cell walls of some
bacteria, protecting the cell surface and sometimes helping to glue the
cell to surfaces.
⫸ cell wall Answer: A rigid layer of nonliving material that surrounds
the cells of plants and some other organisms.
⫸ centrosome Answer: A structure in animal cells containing centrioles
from which the spindle fibers develop.
⫸ chloroplast Answer: An organelle found in plant and algae cells
where photosynthesis occurs
⫸ chromoplast Answer: a colored plastid other than a chloroplast,
typically containing a yellow or orange pigment.
⫸ crista (pl. cristae) Answer: the folds of the inner membrane of
mitochondria. The site of the electron transport chain
⫸ cytoskeleton Answer: A network of fibers that holds the cell together,
helps the cell to keep its shape, and aids in movement
, ⫸ endoplasmic reticulum (rough or smooth) Answer: extensive
interconnected network of membranous channels called cisternae, some
have ribosomes covering it and others don't.
protein and lipid synthesis
⫸ extracellular matrix Answer: The substance in which animal tissue
cells are embedded, consisting of protein and polysaccharides.
⫸ flagellum (pl. flagella) Answer: Long, slender extension used for
locomotion by some bacteria, protozoans, and sperm.
⫸ gap junction Answer: A type of intercellular junction in animal cells,
consisting of proteins surrounding a pore that allows the passage of
materials between cells.
⫸ Golgi complex Answer: a cell organelle that helps make and package
materials to be transported out of the cell
⫸ granum (pl. grana) Answer: stack of chlorophyll-containing
thylakoids in a chloroplast
⫸ intermediate filament Answer: A component of the cytoskeleton that
includes filaments intermediate in size between microtubules and
microfilaments.
