QUESTIONS AND CORRECT DETAILED
ANSWERS
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.
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.
prokaryotic cell - ✔✔✔ Correct Answer > small, simple, single-cell
organisms; bacteria are the most prevalent kind. Do not contain a nucleus
or any other organelle.
protist - ✔✔✔ Correct Answer > Single-celled eukaryote.

ribosome - ✔✔✔ Correct Answer > the molecular machines that use
the instructions contained in the DNA to build all the proteins needed by
the cell.
vacuole - ✔✔✔ Correct Answer > specialized mainly for storage. Their
membranes do not fuse with the membranes of other cellular
components.
vesicle - ✔✔✔ Correct Answer > specialized for transport and some
other functions. Their membranes can fuse with the plasma membrane,
allowing them to empty their contents into the extracellular space. Also
may fuse with the membranes of the endoplasmic reticulum and Golgi
apparatus, allowing them to empty their contents into those organelles.
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.
