Cell Division and Mitosis

Why do cells have to remain small?

• Being large puts to much strain on thier DNA

• Being larger makes it harder for the cell to move nutrients and dispose of waste

• larger cells are a bigger target for dangerous pathogens

• Larger cells create tumors that are bad for the body

Which phase of the cell cycle is when the cell is growing, replicating its DNA and preparing for division

• Interphase

• Prophase

• Metaphase

• Anaphase

In which phase of the cell cycle does the chromatin condense into chromosomes and the nuclear envelope start to disappear

• Interphase

• Prophase

• Metaphase

• Anaphase

In which phase of the cell cycle do the chromosomes line up in the middle of the cell along the metaphase plate, then the spindle fibers connect to the centromeres (center of chromosomes)

• Interphase

• Prophase

• Metaphase

• Anaphase

In which phase of the cell cycle do the spindle fibers pull the sister chromatids apart and to opposite ends of the cell

• Interphase

• Prophase
