What is a cell?
A.where the nucleus gets its power
B.the basic unit that makes up living
things
C.thick fluid where the organelles are
D.they assemble compounds called
proteins
B. the basic unit that makes
up living things
What are organelles?
A.small structures that perform specific
functions in a cell
B.the thin covering that surrounds a cell
C.the thick fluid where things are
suspended
D.only small ball shaped things
A. small structures that
perform specific functions
in a cell
What is the nucleus?
A.they assemble compounds called
proteins
B.the basic unit that makes up living
things
C.thick fluid where the organelles are
D.the part that directs the activities of a
cell
D. the part that directs the
activities of a cell
Which one is only in a plant?
A.nucleus
B.cell wall
C.cell membrane
D.cytoplasm
B. cell wall
What is a cell membrane?
A.the rigid outer layer that helps it stand
up
B.the part that makes proteins
C.a flexible covering that allows some
things in and some out
D.sacs that store fluids
C. a flexible covering that
allows some things in and
some out
What is cytoplasm?
A.ball shaped organelles
B.thick fluid that holds organelles
C.thick membranes around cells
D.they assemble compounds called
proteins
B. thick fluid that holds
organelles
These are tiny, not surrounded by
membranes, and assemble compounds
called proteins.
A.lysosomes
B.vacuoles
C.nucleus
D.ribosomes
D. ribosomes
This receives proteins, then processes
them for shipment out of the cell. It is a
system of membranes. It modifies
proteins.
A.endoplasmic reticulum
B.golgi apparatus
C.lysosome
D.vacuole
B. golgi apparatus
These ball shaped organelles help break
down nutrients and old cell parts. They
are common in plants but rare in
animals.
A.ribosomes
B.vacuoles
C.lysosomes
D.golgi apparatus
C. lysosomes
These are membrane-bound sacs that
are filled with fluid. Animal cells may
have some small ones, but plant cells
usually have one large one.
A.ribosomes
B.vacuoles
C.cell wall
D.golgi apparatus
B. vacuoles
Which are usually only found in plants?
A.ribosomes
B.nucleus
C.chloroplasts
D.mitochondria
C. chloroplasts
What is the job of chloroplasts?
A.they are the power plants of cells
B.they process proteins for shipment
C.they are a system of tubes for
materials to pass through
D.they use energy to make food through
photosynthesis
D. they use energy to make
food through
photosynthesis
These large, peanut-shaped organelles
are the power plants of cells. Sugars
break apart in them making carbon
dioxide, water, and energy.
A.ribosomes
B.nucleus
C.chloroplasts
D.mitochondria
D. mitochondria
This is a system of membranes and
tubes that create passageways for
materials to pass through. They can
control levels of chemicals and break
down toxic substances.
A.endoplasmic reticulum
B.golgi apparatus
C.chloroplasts
D.lysosomes
A. endoplasmic reticulum
