multipotent
totipotent
pluripotent
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.
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
Compare and contrast mitosis and cytokinesis.
both: forms of division. Mitosis = division of nucleus/DNA. Cytokinesis = division of cytoplasm/organelles.
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.
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.
