in vitro fertilization (IVF)
when a sperm and an egg are joined in a petri dish, and the embryo is implanted into the mother's uterus
also known as reproduction; two daughter cells are produced that are genetically identical to each other and to the parent cell
the structures that contain most of the organism's DNA; where most genes are located in a eukaryotic cell
1) replaces damaged or lost cells
2) permits growth
3) allows for reproduction
three things cell division does
single-celled organisms reproduce by simple cell division, and there is no fertilization of an egg by a sperm
the type of cell division responsible for asexual reproduction and growth and maintenance of multicellular organisms; the nucleus and its contents divide evenly into two daughter nuclei
requires fertilization of an egg by a sperm using a special type of cell division called meiosis
the stage of the cell cycle that a cell performs its normal functions, doubles everything in its cytoplasm, and grows in size
mitotic (M) phase
the phase of the cell cycle that includes two overlapping processes: mitosis and cytokinesis
