Biology chapter 5

the seperation cycle in the cell cycle

the growth and divison of a cell

holds chromotids together

when chomosomes coil, spindle fibers form, and the nuclear membrane breaks down

chromosomes line up and spindle fibers attach

centromeres didvide, chromosomes move to oppisite ends of the cell

two new nuclear membranes form, and the chromosomes uncoil

cytoplasm pinches the cell in two to form two new cells

gap one growth, cells spend most time in this phase

Gap two growth and final checkpoint before mitiosis 

synthesis DNA is copied

G1,S, and G2

the DNA of a cell

When cells divide more often the healthy cells

The cancer cells remained clustered

when DNA copies itself, and ends with two daughter cells

uses more energy then asexual prodution, needs mates, only female can bear the child, takes time, increases genetic variation

cost less energy the sexual reproduction, every asexual organism can bear child, can produce many off spring fast, all offspring are identical

potential to develop into differnt cells or tissues

group of cells that work together to perform a similar function

organs work together to maintain homeostasis

Programed cell death

stem cell that can grow into any other cell type

A new organism forms from the parent

parent organism splits into pieces and each piece can form into a new organism
