Module 2 chapter 5 Flashcards
4 methods of getting in and out of the cell
- Diffusion
- Facilitated diffusion
- Osmosis
- Active transport
Is the transportation in Diffusion active or passive

What is the movement of the molecule during diffusion
High to low concentration
What is the movement of the molecule during diffusion
High to low concentration
What is the movement of the molecule during active transport
Against concentration gradient
What is the movement of the molecule during bulk transport
In or out
What is the movement of the molecule during Facilitated diffusion
Down concentration gradient
are proteins needed in diffusion
No
are proteins needed in Osmosis
No
are proteins needed in Facilitated diffusion
Yes
are proteins needed in Active transport
Yes
are proteins needed in Bulk transport
No
What is the water potential of pure water
0
What is the scientific word for the cell bursting
Cytolysis
What is the scientific word for the cell to shirvel
Crenate
When will the cell crenate
When there’s a higher water potential in the cell than the water around it
When will the cell cytolysis
When there’s a higher water potential in the water around than in the cell
What is plasmolysis
When the membrane shrinks away from the cell wall
Will a higher water potential dissolve more or less salt than a lower water potential
Less salt
What is facilitated diffusion
Pass through protein channels called facilitated proteins
What 4 factors affect rate of diffusion
- Concentration gradient
- Temperature
- Surface area
- Type of molecule
Will a higher concentration gradient increase or decrease the rate of diffusion
Increase
Will a higher temperature increase or decrease the rate of diffusion
increase
Will a higher surface area increase or decrease the rate of diffusion
increase
Will a larger molecule increase or decrease the rate of diffusion
Decrease, smaller molecules move faster
What molecules can diffuse through a cell membrane
- O2
- CO2
