Mitosis
Cell division that results in two daughter cells
Cytokinesis
Occurs at the end of mitosis and separates the cells
Cell cycle
A series of events that lead up to the replication of dna
Prophase
The first stage of cell division where the chromosomes become visible
Metaphase
second stage where Chromosomes become attached to spindle fibers
Anaphase
Chromosomes move to opposite poles
Chromosomes
Carries genetic information
Centromere
The place where spindles attach
Heredity
the passing on of physical or mental characteristics genetically from one generation to another.
Genetics
the study of heredity and the variation of inherited characteristics.
Self pollination
Plant can feed itself
Cross-pollination

Diploid
1.
(of a cell or nucleus) containing two complete sets of chromosomes, one from each parent.
Haploid
One set of genes
Gametes
a mature haploid male or female germ cell which is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
Zygote
a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.
Chiasmata
a point at which paired chromosomes remain in contact during the first metaphase of meiosis, and at which crossing over and exchange of genetic material occur between the strands.
