Abiotic - ✔✔✔ Correct Answer > Non-living, may be within or made by
a living organism.
Cell wall - ✔✔✔ Correct Answer > Protective layer for prokaryotes,
made of peptidoglycan.
central vacuole - ✔✔✔ Correct Answer > In a plant cell. can be a place
of storage, degradation, defense, and even physical support for
the cell.
centriole - ✔✔✔ Correct Answer > A barrel-shaped structure only
present in animal cells. plays a role in the spatial organization of
the cell and cell division.
chloroplast - ✔✔✔ Correct Answer > In a plant cell. Chloroplasts
capture energy from the sun and use that energy to build sugar
molecules.
,Page 2 of 47
chromatin - ✔✔✔ Correct Answer > the material of which the
chomrosomes of organisms are composed. Consists of protein,
RNA and DNA
chromosome - ✔✔✔ Correct Answer > A single molecule of DNA.
cilium - ✔✔✔ Correct Answer > a short, microscopic, hairlike vibrating
structure. Occurs in large numbers on the surface of certain
cells.
cytoplasm - ✔✔✔ Correct Answer > the fluid that occupies the space
inside the cell. the space in which the chemical reactions that
enable life take place.
cytoskeleton - ✔✔✔ Correct Answer > formed by a series of protein
filaments, and is both a scaffold for the cell structure and a
framework for many cellular activities, including movement and
cell division.
endoplasmic reticulum (ER) - ✔✔✔ Correct Answer > a series of sacs
and tubes. put together or assemble the proteins and other
cellular components.
,Page 3 of 47
eukaryotic cell - ✔✔✔ Correct Answer > larger, and most often they are
multicellular organisms, including plants, animals, and fungi.
flagellum - ✔✔✔ Correct Answer > External appendage to a
prokaryote.
fungus - ✔✔✔ Correct Answer > include molds and mushrooms, are
also eukaryotes.
golgi apparatus - ✔✔✔ Correct Answer > Where the proteins
assembled in the ER are delivered to different parts of the cell,
or in multicellular organisms, to different parts of the body.
lysosome - ✔✔✔ Correct Answer > specialized vesicles found only in
animal cells. Contain powerful digestive enzymes that can
recycle cellular parts or destroy external invaders.
microtubule - ✔✔✔ Correct Answer > Formed by centrioles. filament
type of the cytoskeleton. also form appendages such as the
flagellum of the sperm cell and the cilia of the cells of the
respiratory system.
mitochondrion - ✔✔✔ Correct Answer > takes fuel in the form of sugar
(glucose) and convert it to usable energy ATP.
, Page 4 of 47
nuclear envelope - ✔✔✔ Correct Answer > a double-layered membrane
surrounding the nucleus. studded with pores that allow
information from inside the nucleus to enter the cytoplasm.
nucleoid - ✔✔✔ Correct Answer > Region ina prokaryote, where the
DNA molecule is present. Does not have a surrounding
membrane.
nucleoulus - ✔✔✔ Correct Answer > Within the nucleus. not bound by a
membrane. Instead, it is an aggregate of molecules where
ribosomes, another type of nonmembranous organelle, are
assembled.
organelle - ✔✔✔ Correct Answer > a specialized structure formed
when a specific set of molecules bond, providing a subunit that
performs a particular function within the cell. Many, but not all,
are structures enclosed by a membrane.
plasmid - ✔✔✔ Correct Answer > a genetic structure in a cell that can
replicate independently of the chromosomes, typically a small
circular DNA strand in the cytoplasm of a bacterium or
protozoan.
