1.
1 point
_______make up the cell membrane
2.
1 point
which type of environment do animal cells, including red blood cells function best in?
3.
1 point
when energy is required to move a substance across a membrane, against the concentration gradient.
4.
1 point
pressure within the cell caused by the central vacuole filling with water.
5.
1 point
which is a collapse of the plant cell’s cytoplasm due to the shrinking of the cell due to the loss of water. Causes there to be space between the cell membrane and the cell wall.
6.
1 point
when a cell takes in fluids
7.
1 point
solution with higher solute concentration
8.
1 point
is a protein that serves the function of moving other materials within an organism.
9.
1 point
binds to the molecule, which changes its shape and this allows the molecule to pass through the membrane.
10.
1 point
Hydrophobic
11.
1 point
a solution in which the concentration of solutes is GREATER than the cytoplasm of the cell, causes cell to SHRINK due to osmosis.
12.
1 point
when a cell takes in solid material
13.
1 point
Who does Jarret Like
14.
1 point
_______are embedded in the cell membrane
15.
1 point
How does salt cure meats?
16.
1 point
when a cell bursts due to internal pressure
17.
1 point
Solution having the same concentration of solutes as the cytoplasm of the cells, net movement in water is equal
18.
1 point
______make up the interior of the cell membrane
19.
1 point
which type of environment do plant cells function best in?
20.
1 point
What type of environment outside the cell would cause water to go into the unicellular organisms body?
21.
1 point
Hydrophilic
22.
1 point
condition plant cells require on the outside
23.
1 point
forms tiny pores in the membrane for specific substances to pass through.
24.
1 point
double layer phospholipids form
25.
1 point
The movement of molecules across a membrane with the concentration gradient (high to low) without the expenditure of chemical energy.
26.
1 point
when a cell comes in contact with a substance which it surrounds with the plasma membrane, which is then pinched off into the inside of the cell.
27.
1 point
a solution in which the concentration of solutes is LESS than in the cytoplasm of the cell, causes cell to EXPAND due to osmosis.
28.
1 point
solution with a high water concentration
29.
1 point
What do unicellular organisms use to collect and pump water out of their bodies?
30.
1 point
how does salt cure meats?
31.
1 point
passive transport that requires a protein factor or helper in the membrane to allow the substance to pass through. Still does not require energy.
32.
1 point
solution with lower solute concentration
33.
1 point
solution in which the solute concentration is the same
34.
1 point
when vacuoles and vesicles fuse to the plasma membrane to release their contents into the solution outside the cell.
35.
1 point
_________make up the exterior of the cell membrane.
36.
1 point
Turgor pressure is caused by a
37.
1 point
Cytolysis is caused by a
