Reproduction:The formation of new individuals 1 of 8 characteristics of life
2 Types of reproductionAsexual and Sexual

Asexual Reproduction:1) Single parent cell dividing2) Offspring genetically identical3) Prokaryotic cells like bacteria4) Simple, hast and efficient process

Sexual reproduction:1) Offspring produced by fusion of two separate parent cells.
2) Offspring not identical to parents3) Eukaryotes4) Slower and creates fewer offspring

Cell Division:Before a cell gets too large it divides forming two “daughter” cells.

Chromosomes:Chromosomes are a structure of DNA and protein that contain the genetic information.
Role in cell division:Holds the genetic information]Prepares/packs it for cell division

Prokaryotic Chromosomes:Located in the cytoplasmContain a single , circular DNA chromosome.
Division called binary fission- produces two identical organisms.

Eukaryotic chromosomes:Located in the nucleus.Chromosomes made up of sister chromatids attached at the centromere.
