Cell Mitosis

Nucleus

Organelle that controls all the activities of a cell and contains hereditary material made of proteins and DNA

Mitosis

The process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Chromosome

Structure in a cells nucleus that contains hereditary material

asexual reproduction

a type of reproduction fission budding and regeneration in which a new organism is produced from one organism and has DNA identical to the parent

Organism

Any living thing uses energy is made of cells reproduces responds grows and develops

Sexual Reproduction

a type of reproduction in which two sex cells usually an egg and a sperm join to form zygote which will develop into a new organism with a unique identity

Sperm

haploid sex cell formed in male reproductive organs

Egg

haploid sex cell formed in the female reproductive organs

Fertilization

in sexual reproduction the joining of a sperm and egg

zygote

new diploid cell formed when sperm fertilizes an egg; will divide by mitosis and develop into new organism

diploid

cell whose similar chromosomes occur in pairs

haploid

cell that has half the number of chromosomes

meiosis

reproductive process that produces four haploid sex cells from one diploid cell and ensures offspring will have the same number of chromosomes as parent organisms

Hereditary

The passing of traits from parents to offspring

DNA

deoxyribonucleic acid the genetic material of all organisms made up of two twisted strands of sugar phosphate molecules and nitrogen bases

gene

Section of DNA on a chromosomes that contains instructions for making specific protiens

RNA

Ribonlucleic acid a type of nuclei acid that carries codes for making proteins from the nucleus to the ribosomes

Mutation

any permanent in gene or chromosome some of the cell may be beneficial harmful or have little effect on organism
