The phase of mitosis in which the sister chromatids separate from each other is called ______________________.
anaphase

The sequence of growth and division of a cell makes up ____________.
Mitosis
The Cell Cycle
Interphase
10
Chromosomes duplicate during ___________________ of interphase.
G1 phase
G2 phase
S phase
10
The phase of mitosis in which chromosomes line up in the middle of the cell is known as ____________.
metaphase
15
Sister chromatids are held together by a structures called _______________________.
spindle fibers
centromeres
centrosomes
10
The division of the nucleus or genetic material is known as __________________.
the cell cycle
mitosis
cytokinesis
10
Zygotes are considered to be ____________________.
multipotent
totipotent
pluripotent
10
The instance where stem cells are limited to becoming anything they want and are restricted to forming cells in the tissues where they are at is known as being __________.
multipotent
pluripotent
totipotent
10
The uncontrolled division of cells is known as _______________________.
Describe the main difference between telophase in plant cells and in animal cells.
In plant cells, the cell plate forms; in animal cells, a cleavage furrow forms.

Explain how chromosomes, sister chromatids, and chromatin are related.
Chromosomes are made up of two sister chromatids, and the sister chromatids are made up of chromatin.
20
State two of the three factors that influence cell size and explain how both influence cell size.
DNA - if cells too large, too hard to keep up with protein demands. SA/V - too big for cell to transport materials fast enough. Diff. -effective over short dist
25
Compare and contrast mitosis and cytokinesis.
both: forms of division. Mitosis = division of nucleus/DNA. Cytokinesis = division of cytoplasm/organelles.
20
Define cell division. What is the overall result of cell division?
Cell division is the process by which two daughter cells are formed from one original cell. The result is two genetically identical cells.
20
Explain why it’s necessary for a cell’s chromosomes to be distributed to its daughter cells in such a precise manner.
to ensure the correct amount of DNA gets distributed to the daughter cells; otherwise the cell could have a mutation and/or not be a viable cell and die.
