100
The movement of any substance from high concentration to low concentration, with or without a membrane
What is Simple Diffusion?
100
This is something active transport requires that passive transport does not.
What is energy/ATP?
100
The definition of osmosis.
What is the diffusion of water?

The two main phases of the cell cycle.
What are interphase and mitosis?
100
Name the four stages of mitosis.
What is prophase, metaphase, anaphase, telophase?
200
The movement of any substance through a membrane, from high to low concentration through a membrane protein.
What is Facilitated Diffusion?
200
During active transport, solutes move [with/against] the concentration gradient.
What is against the concentration gradient?
200
Osmosis is a type of [active/passive] transport.
What is passive?
200
When a cell is in interphase, DNA is in the form of [chromatin/chromosomes]. When a cell is in mitosis, DNA is in the form of [chromatin/chromosomes].
What is chromatin, chromosomes?
200
The stage of mitosis depicted here:
What is metaphase?
300
The type of diffusion demonstrated in this picture:
What is Osmosis?
300
The type of active transport demonstrated in this picture.
What is exocytosis?
300
Red blood cells placed in a solution with the same concentration of solutes as inside the cell will neither gain nor lose water. This solution is called...
What is isotonic?
300
This occurs during the G1 phase.
What is cell growth?

What is anaphase?
400
During passive transport, particle move from ________ concentration to _______ concentration.
What is high to low concenctration?
400
The type of transport depicted in this image.
What is molecular transport?
400
When a plant cell is placed in pure water, water moves into the cell causing it to swell. This happens because the solution outside the cell is...
What is hypotonic?
400
Before a cell can divide into 2 cells, it must replicate its DNA. The identical copies of chromosomes that separate in mitosis are called…
What are sister chromatids?
400
The stage of mitosis defined by the cells genetic material condensing into chromosomes, the nuclear envelope dissolving, and spindle fibers beginning to form.
What is prophase?
500
Which of the following is NOT true about cell membranes?
1) It is selectively permeable
2) It is a fluid mosaic with many proteins and channels
3) Anything can pass through it
4) It controls what goes in and out of the cell
What is 3) Anything can pass through it?
500
An example I gave in class of when your cells would need to use active transport is...
What is
1) Sodium / Potassium Pump to maintain electrical gradient so nerve cells can send signals to muscles.
2) Hydrogen ion pump during photosynthesis to generate ATP
500
When you get a leech stuck to your leg, you add salt and then the leech will shrivel up and fall off. That is because the salt on the outside is this type of tonicity.
What is hypertonic?
500
The role checkpoints play in the cell cycle.
What is pauses the cell cycle until key events are completed correctly, ensuring that the cell is ready to move to the next stage. This prevents errors in DNA replication and chromosome segregation, which is crucial for maintaining genetic stability and avoiding diseases like cancer.
500
The two reasons cells go through division.
What are growth and repair?
