Diffusion
In what direction does diffusion occur?
High concentration to low concentration
What is the diffusion of water?
Osmosis
What are the three parts of interphase?
G1, S, G2
How many stages make up mitosis?
Four
How many times does Meiosis go through PMAT?
2x
What type of diffusion requires molecules to pass through proteins in the membrane?
Facilitated Diffusion
When placed in a hypertonic environment, where will water move?
Out of the cell
In which stage of interphase does DNA replication occur?
S-Phase
Using their full names, list the stages of mitosis in the correct order.
Prophase, Metaphase, Anaphase, Telophase
Genetically, how do the daughter cells compare to the parent cell?
Genetically unique
Diffusion is what kind of transport?
Passive Transport
In what direction does water move during osmosis?
Low solute to high solute OR high water to low water
What percentage of the cell cycle is made up of interphase?
90%
How many cells are produced during mitosis?
2
How many cells are produced during meiosis?
4
Will hot or cold temperatures cause molecules to diffuse faster?
Hot - the molecules are moving faster.
There is 60% solute in the cell, and 50% solute in the solution. Where will water move?
Into the cell
What is the term for programmed cell death?
Apoptosis
In which stage do sister chromatids split and move to the poles of the cell?
Anaphase
If a parent cell has 46 chromosomes, how many chromosomes will each of the four daughter cells have?
23
What are two other names for the cell membrane?
A cell is 75% water in the cell, and there is 50% water outside of the cell. Where will water move?
What is the result of abnormal cell growth?
Cancer
What two important things happens during prophase?
Chromatin condenses into chromosomes, and nuclear envelope breaks down.
In which phase do homologous chromosomes line up in pairs? (Be specific!)
Metaphase 1
