asexual reproduction reproduction that requires only one parent and produces offspring that are genetic copies of the parent
binary fission a form of asexual reproduction in which a single parent cell replicates its genetic material and divides into two equal parts
budding a form of asexual reproduction in which areas of an individual may undergo repeated mitosis and cell division and can develop into an identical organism
cancer the result of uncontrolled cell division
cell cycle the three stages of the life of a cell, including the sun, the moon, planets and the stars
clone an identical genetic copy of an organism's parent
cytokinesis the final stages of the cell cycle, which separates the two nuclei and cell contents into two daughter cells
fragmentation a form of asexual reproduction in which each fragment of an organism develops into a clone of its parent
interphase the first and longest stage of the cell cycle, in which cells carry out life functions and cells that divide prepare for cell division
mitosis the second, and shortest stage of the cell cycle; the process in which the duplicated contents of the cells nucleus divides into two equal parts
replication the process during which the cell copies 3 billion base pairs of DNA information it the nucleus
spindle fibres tiny tube-like structures made of protein to which chromosomes attach during cell division
spore reproductive cells that grow into new individuals by mitosis
stem cell cells that have the potential to become many different types of cells; two types of stem cells are embryonic stem cells and adult stem cells
