A form of active diffusion where
materials wrapped in vesicles exit
the cell
Random movement of molecules
from high concentration to low
until equilibrium is reached
Solution containing higher solute
concentration than water; causes
a cell to shrink
A form of active diffusion where
materials wrapped in vesicles
enter the cell
Part polar, part non-polar
molecule; a part of the cell
membrane structure
A form of passive diffusion using
a protein channel; high to low
concentration
Structure of the cell membrane;
contains the non-polar zone; acts
as a gate keeper
A form of diffusion requiring
energy; low to high concentration
Organism made up of a single cell
Living things are made up of
cells; cells are basic unit of life;
cells come from pre-existing cells
Outer boundary of the nucleus;
contains pores; controls
movement into & out of nucleus
Solution containing mostly water;
causes a cell to swell
Primitive organism; unicellular;
has no nucleus or organelles
One or more cells working
together for a common function
Scientist who stated that cells
reproduce
cells that have a nucleus and
membrane-bound organelles
Compartments within the cell
which have a particular structure
and function
An organism made up of many
cells
Movement of water from high
concentration
to
low
until
equilibrium
Scientists who discovered that all
plants and animals are made of
cells
21. Which of these is required for aerobic
cellular respiration?
F Carbon dioxide
G Sunlight
H Oxygen
J Chlorophyll
19. A student looking through a light
microscope saw this cell in cytokinesis. This
cell is most likely from —
A a plant
B a virus
C an animal
D a bacterium
22. The picture shows a student’s experiment
with Elodea, a common aquatic plant. Which
change in this experiment is most likely to
increase the volume of oxygen gas that
accumulates in the top of the tube?
F Use fewer plants
G Replace the beaker with a larger container
H Move the light source closer to the beaker
J Reduce the amount of water
23. In a typical animal cell, which component
contains the greatest amount of water?
A Cell membrane
B Cytoplasm
C Ribosomes
D Nucleus
20. In 1665 Robert Hooke observed a thin
slice of cork under a microscope and
presented a drawing similar to the one
shown. Hooke called the structures he
observed —
F chloroplasts
G root hairs
H stomata
J cells
24. The diagram shows a section of a cell
membrane that includes a channel
protein. The function of this protein is to —
A strengthen the outer boundary of the cell
B connect reproductive cells during fertilization
C allow certain substances to enter or leave the
cell
D exchange organelles or chromosomes
between specialized cells
