Because the cell membrane is composed of many small parts that move together as a system, it is said to be _____ _____ (two words).
(a)
Select any substances that can simply diffuse through the cell membrane.
Oxygen gas

Small
Charged
The diffusion of water through the cell membrane along its own concentration gradient is known as (a) .
Select all forms of cell transport that require ATP energy.
Facilitated diffusion
Endocytosis
Exocytosis
Active Transport
The use of a protein pump (ions like Na+, K+, H+, etc.) is an example of ___ because ___.
exocytosis; ions are moved out of the cell
active transport; ATP is required
facilitated diffusion; a protein is needed for transport
endocytosis; ions are moved into the cell
Because cell membranes only allow certain substances to pass through them, they're said to be (a) .
This cell is experiencing which kind of situation?
Hypertonic
Hypotonic
Isotonic
In this kind of situation, the *initial* concentration of water is greatest _____________ the cell.
Inside of
Outside of
In this kind of situation, water will move _____ the cell, causing it to ___________.
into, swell
out of, swell
into, shrink
out of, shrink
In this kind of situation, the solutes will move _____ the cell, causing it to ___________.
into, swell
out of, swell
into, shrink
out of, shrink
TRICK QUESTION Mrs. J! You almost got me. I know the membrane is IMPERMEABLE to the solutes, so they stay put while the WATER moves!
Because cell function is so heavily dependent on effectively transporting materials across the cell membrane, cell size is limited due to the need for a (a) ratio of surface area to volume.
The point of organelles such as the mitochondria, golgi, ER, etc. all having membranes is to ...
Provide extra protection to those critical organelles
Increase surface area for materials transport
Prevent hazardous materials from escaping the organelles and damaging the rest of the cell
All of the above
Which organelle uses digestive enzymes to break down old cellular components and/or invading bacteria/virsus and recycles those components to other organelles for use in building new macromolecules?
Gap junction
Nucleus
Golgi Body
Lysosome
This theory states that membrane bound organelles evolved from once free-living prokaryotes that were engulfed to compose the eukaryotic cells that we observe today.
(a)
Who is the (ATP producing, glycolysis/krebs cycle running) powerhouse of the cell?
(a)
Select all forms of passive transport below.
Diffusion
Facilitated Diffusion
Endocytosis
Exocytosis
Osmosis
Facilitated diffusion occurs when what kind(s) of molecules require a channel or carrier protein to enter the cell membrane?
small, non-polar
large, non-polar
small, polar
large, polar
Which substance would most easily pass through the cell membrane?
Oxygen
