| eukaryotic | cell with membrane bound structures |
| interphase | cell's period of growth and development |
| sister chromatids | one of the two identical strands of DNA that make up a duplicated chromosomes |
| cell differentation | process by which cells become different types of cells |
| complex | made of two or more parts |
| fiber | long muscle cell |
| organ | group of different tissues working together to perform a particular job |
| organ system | group of organs working together to complete a series of tasks |
| stem cell | unspecialized cell that develops into many different cell types |
| tissue | group of similar type of cells that work together to carry out specific tasks |
| mitosis | division of cell's nucleus and contents |
| diploid | describes a cell that has parts of chromosmes |
| dna | genetic information in a cell |
| egg | female sex cell |
| fertilization | joining of an egg and sperm |
| haploid | describes a cell that has only one chromosome from each pair |
| homologous chromosomes | pairs of chromosomes -one inherited from each parent-that have genes for the same traits arranged in the same order |
| meiosis | process in which one diploid cell divides to make haploid sex cells |
| sexual reproduction | production of offspring from the combination of genetic materials from two cells |
| sperm | male sex cell |
| zygote | new cell formed through fertilization |
| asexual reproduction | production of offspring by one parent without meiosis and fertilization |
| budding | asexual reproduction in which a new organism grows on the body of its parent |
| cloning | lab procedure that produces identical individuals from a cell or cells taken from an organism |
| culture | growing living tissue in a laboratory |
| fission | cell division in prokaryotes that forms two genetically identical cells |
| potential | possibility |
| regeneration | asexual reproduction in which a new organism grows from a piece of its parent |
| vegetative reproductive | asexual reproduction in which offspring grow from a part of a parent plant |
| dominant | genetic factor that blocks another genetic factor |
| egg | haploid sex cell formed in the female reproductive organ |
| genetics | study of how traits are passed from parents to offspring |
| heredity | passing of traits from parents to offspring |
| hybrid | offspring of two plants or animals with different forms of the same trait |

| codominance | occurs when both alleles can be observed in the offspring's phenotype |
| conclude | to reach a logically necessary end by reasoning |
| gene | section on a chromosome that has genetic information for one trait |
| genotype | two alleles that control the phenotype of a trait |
| heterozygous | having two different alleles of a gene |
| homozygous | having the same two alleles of a gene |
| incomplete dominance | occurs when the offspring's phenotype is a blend of the parents phenotype |
| phenotype | how a trait appears or is expressed |
| polygenic inheritance | occurs when multiple genes determine the phenotype of a trait |
| punnett square | model used to predict possible genotypes and phenotypes of offspring |
