Cell Membrane
What is the function of the cell membrane?
Controls what can enter or exit the cell.
True or False:
Passive Transport requires ENERGY
FALSE.
True of False:
Active Transport requires energy.
TRUE
Osmosis the movement of _______ across the cell membrane.
(fill in the blank)
WATER
Which type of cell has a nucleus?
eukaryotes
Name the 2 main types of cells that have a cell membrane
1) prokaryotic cells
2) eukaryotic cells
What is the type of Passive Transport that involves the movement of WATER?
Osmosis
Which type of Active Transport moves large molecules OUT OF the cell using energy?
EXOCYTOSIS
In this type of solution, EQUAL amounts of water molecules are entering and exiting the cell. Leaving the cell unchanged in shape & size.
ISOTONIC
What is the function of mitochondria?
Powerhouse of cell
(where ATP energy is made)
What does "Semi permeable" mean?
Example: The cell membrane is semi permeable.
Fill in the blanks in the statement:
Passive Transport moves particles from a ______ concentration to a _______ concentration.
(must have 2 correct responses to get the points)
1) HIGH
2) LOW
Which type of Active Transport moves molecules INTO the cell using energy?
ENDOCYTOSIS
When there is more of a substance in one area than there is in another area, we call this a __________ gradient.
fill in the blank.
CONCENTRATION gradient
Name one organelle you can find only in a plant cell.
chloroplast, cell wall etc.

In other words, the bilayer in the cell membrane is composed of ___________?
Phospholipid Bilayer
This type of Passive Transport uses a PROTEIN to HELP move molecules across the membrane.
Facilitated Diffusion
Fill in the blanks:
Active Transport moves molecules from a _______ concentration to a ______ concentration using ______.
(must have all 3 correct responses)
1) LOW
2) HIGH
3) Energy
