|
Name the phases of the cell division.
|
Interphase, (Mitotisis) prophase, metaphase, anaphase, Cytokinesis
|
|
|
Which is the longest phase in Mitois?
|
Prophase
|
|
|
What comes out of the centrioles?
|
spindle fibers
|
|
|
What do the spindle fibers do?
|
form a bridge between the ends of the cell and pull the chromotids apart.
|
|
|
What is a chromotid?
|
The chromosome consists of two rod like parts called chromotids?
|
|
|
What is a centromere?
|
The centromere holds the to daughter chromatids together?
|
|
|
What happens in the Interphase?
|
Cell grows to full size size. It replicates the DNA (duplicate chromosomes), produces centrioles needed for division.
|
|
|
What happens in Prophase?
|
Chomosomes condense and become visible (via a microscope), the pair of centrioles move to opposite sides of the nucleus, spindle fibers form a bridge and the nucleur envelope (membrane breaks down).
|
|
|
What happens in Metaphase?
|
Each chromosome attaches to a spindle, the sister chromodids line up (at the equator).
|
|
|
What happens in Anaphase?
|
The centromere splits pulling the chromotids apart into two chromosomes, these chromosomes are drawn by the spindles to the opposite ends of the cell. The cell stretches out.
|
|
|
What happens in Telophase?
|
Spindle fibers disapear, cell continues to split, nuclear membrane disappears ???
|
|
|
What happens in Cytokinesis?
|
The cell splits into two daughter cells each ending up with an identicall set of chromosomes and about half the organelles of the parent cell.
