Growth of new organisms without the fusion of nuclei (sexual reproduction). Usually involves one parent and leads to clones (genetically identical offspring).
Division of a cell into two equally sized cells (a type of asexual reproduction). Most bacteria do this.
Division of a cell where one begins as an outgrowth of the parent cell. A type of asexual reproduction.
Asexual reproduction in which new individuals receive genetic information from a single parent cell (instead of a combination of two parents).
fusion of nuclei from two gametes (sex cells) during sexual reproduction. (Resulting cell is a zygote).
Reproductive cells (like sperm or eggs). Contains one set of unpaired chromosomes ("normal" cells contain two sets). During sexual reproduction two gametes fuse together.
Special type of cell division resulting in gametes (sex cells with half of the "normal" amount of genetic information).
Asexual reproductive cells that can develop directly into a complete organism (usually found in fungi).
the first cell resulting from the fusion of two gametes. Contains a full set of genetic information (half from a sperm, half from an egg).
Steps to Cloning
1.Obtain an egg cell and remove its contents. 2.Obtain a somatic (normal) cell of the organism you would like to clone and extract its DNA. 3.Inject the DNA into the empty egg cell. 4.Treat with chemicals until it begins to grow. 5.Implant the egg into a surrogate. 6.Wait until birth.
Artificial Embryo Twinning
Purposely dividing growing ball of cells. When this occurs naturally it forms twins.
Uterus (what happens during ovulation and beyond?)
Thickens and new blood vessels, preparing to support a growing embryo.
structure that follicle becomes after ovulation. Begins releasing progesterone, which maintains a thickened uterus.
