Involved in cell reproduction
Site of protein synthesis
Outer boundary; controls
what moves into and out of
the cell
Contains DNA & nucleolus;
control center
Site of photosynthesis
Rigid outer layer; provides
structural support in plant
cells
Breaks down glucose and
produces energy;
powerhouse
Packages and delivers
proteins and lipids; UPS
DNA strands containing the
cells’ instructions;
decondensed chromosomes
Cell digestion using
enzymes; garbage disposal
Production and storage of
ribosomes; dark spot in the
nucleus
Storage of water and waste;
large in plants
Transporter of proteins and
lipids; highway
Jelly-like substance; contains
the organelles
Solution containing mostly
water; causes a cell to swell
Movement of water from
high concentration to low
until equilibrium
Solution with equal solute to
solution ratio; cell placed in
this solution stay the same
Any living thing as a whole;
may be unicellular or
multicellular
19. Under a microscope, a series of cells are
observed that lack membrane-bound internal
organelles. Which of these is the most likely cell
type?
A Plant cell
B Animal cell
C Eukaryotic cell
D Prokaryotic cell
20. Which of these supports the cell theory as it
is stated today?
F New cells are produced by division of existing
cells.
G All organisms are composed of more than one
cell.
H Cells must contain a nucleus.
J Not all cells are alive
21. A student observes that a type of eubacteria
contains chlorophyll. Which of these does this
type of bacteria have in common with plants?
A It is photosynthetic.
B It contains vascular tissues.
C It contains mitochondria.
D It is heterotrophic.
26. Which is an important function of the cell
structure in this model?
A Controlling passage of materials
B Packaging cell products for export
C Transferring hereditary material to offspring
D Preventing a cell from bursting due to osmosis
22. What do viruses need to reproduce?
A Other viruses
B Host organisms
C A nutrient medium
D An enzyme solution
23. Which discovery was essential to the
concept that all life forms have cells as basic
units?
F Water is the chemical solvent involved in many
cell processes.
G New cells are produced from the division of
existing cells.
H Some substances in organisms exist outside of
cells.
J Cells are dependent on energy and nutrients from
external sources.
24. The oxygen content in the atmosphere of the
early Earth is thought to have
increased significantly once which of these
developed?
A Amino acids
B Archaebacteria
C Photosynthetic bacteria
D Mitochondria
25. The main reason that eating salty foods
makes a person thirsty is that
additional fluid is needed to —
F increase the salinity of the blood
G dissolve salt crystals in the stomach
H maintain the fluid balance in the cells
J prevent damage to the lining of the throat
27. Which is the name of structure 4?
A Nucleus
B Ribosome
C Vacuole
D Cell wall
28. Many marine invertebrates have body
surfaces that are permeable to water
but not to salt. Osmosis can change the
pressure of their body fluids. Fortunately, the
ocean is very stable in its salt content. What
would happen if a jellyfish were placed in a very
low-salt environment such as an estuary?
A It would gain water from the environment.
B It would gain nutrients from the water in the
environment.
C It would lose proteins into the water.
D It would lose salt into the water.
