This type of solution will cause an animal cell to shrink?
What is hypertonic?
100
What does it mean to move down the concentration gradient?
To move from HIGH to LOW.
200
The term used to describe the diffusion of WATER
What is osmosis?
200
This type of passive transport allows large molecules like glucose to enter and exit through specific protein channels. The protein makes it easy.
What is facilitated diffusion?
200
Lemonade is a mixture of sugar and water.
Which is the solute?
What is sugar?
200
The protein pump is used during which type of transport?
Active Transport
200
True or False: All cells contain a cell membrane.
True
300
The type of solution where the concentration of solute is equal on both sides
What is an isotonic solution?
300
In active transport, molecules move from ______ to _______ concentrations.
What is low to high?
300
This type of solution has a lower concentration of solute; as a result if a cell is placed in it, the cells will usually swell
What is hypotonic solution?
300
The type of transport that has molecules move from a LOW to HIGH concentration.
Active Transport
300
Perfume being sprayed in a classroom and moving from an area of high concentration to low concentration is an example of what type of passive transport?
What is DIFFUSION?
400
In passive transport, molecules move from a _______ to ______ concentration
What is high to low?
400
Active transport requires the presence of this:
What is energy(ATP)?
400
This type of solution has a higher concentration of solutes than solvent.
What is hypertonic solution?
400
How are osmosis, simple diffusion, and facilitated diffusion similar?
They all move from high to low concentrations.
They are all passive transport.
400
In this form of active transport, the molecules inside a vesicle are pushed OUT through the cell membrane.
What is EXOCYTOSIS.
500
This term means that the cell membrane lets some things in while keeping other things out.
What is selective permeability?
500
Which type of transport is shown below?
What is facilitated diffusion?
500
The main function of the cell membrane is to....?
What is to regulate what enters and exits the cell.

In biology, what liquid is typically used as a solvent?
WATER
500
In this form of active transport, the molecules outside a cell are PULLED IN and contained in a vesicle.
What is ENDOCYTOSIS.
