Compared to small cells, large cells have more trouble with this.
What is moving needed materials in and waste product out?
100
This happens when a cell divides.
What is each daughter cell recieves its own copy of the parent cells DNA?
100
A multicellular organism begins life as a single cell - a fertilized egg witha complete set of chromosomes. This cell divides to become two cells, then 4, then 8 cell and so on. Describe what happens during this process.
What is Chromosomes are duplicated before cell division so that each new daughter cell has a complete set?
100
During this phase in the cell cycle mitosis happens.
What is M phase?
100
Telophase is part of the M phase (true or false).
What is TRUE?

The centromere is......
What is region of a chromosome where 2 sister chromatids attach?
200
One difference between cell division in plant cells and in animal cells is that plant cells have this?
What is a cell plate?
200
What explains why normal cells grown in a petri dish tend to stop growing once they have covered the bottom of the dish.
What is contact with other cells stops cell growth?
200
In eukaryotic cells, the timing of the cell cycle is regulated by this.
What is cyclins?
200
Cancer is a disorder in which some cells have lost the ability to control this.
What is growth rate?
300
When during the cell cycle are chromosomes visible.
What is ONLY during cell division?
300
An advantage of sexual reproduction over asexual reproduction is that sexual reproduction does this.
What is provides genetic diversity?
300
Stem cells are important because of this.
What is They have the ability to develop into other types of cells?
300
The rate at which wastes are produced by a cell partially depends on the cell's what?

What is reversing damage from a heart attack?
400
During early development, all cells in the embryo of a multicellular organism are identical. Later in development, the cells become specialized through a process called this.
What is differentiation?

What is apoptosis?
500
Embryonic stem cells gathered from the inner cell mass of the blastocyst are called ______________ because they can develop into most, but not all human cell types.
What is Pluripotent?
