**Use PowerPoint to complete this side Notes: Sexual/Asexual Reproduction I. Reproduction A. * ___Asexual reproduction_____ - a new organism is produced from one parent organism. (growing a new plant from a piece of one) 1. -Many plants can reproduce asexually- ___vegetative propogation________________ Ex. __strawberries, potatoes, ivy____ 2. An organism with no nucleus divides into two identical organisms by __binary fission___. Example: _amoeba and bacteria__ (amoeba) 3. __Budding_____ - a small, exact copy of the adult grows from the body of the parent. Example: __yeast, hydra_____ (yeast) 4. In __regeneration______, a whole new organism grows from each piece of the parent. Example: __sea star, sponge, planaria___ (planaria) 1.The amoeba is preparing for _cell division___ by copying its DNA. 2. An amoeba prepares to divide by expanding its _cell membrane_ Meanwhile, bundles of DNA known as__chromosomes___ travel to either side. 3. The amoeba has divided into two __daughter cells__. Each of these cells has one complete copy of DNA. The process of _reproduction___ is complete!!! ____________________________________________________________________________ B. *__sexual reproduction_ - two sex cells, usually an egg and a sperm, come together. 1. *__Fertilization_____ - the joining of an egg and a sperm, generally from two different organisms of the same species. a. _Sperm__ are formed in the male reproductive organs. (testes) b. _Eggs______ are formed in the female reproductive organs. (ovaries) c. A cell that forms from fertilization is a __zygote____. 2. Following fertilization, _cell division (mitosis)_ begins and a new organism develops. C. _Sexual___ reproduction produces offspring that are more diverse then __Asexual_______ reproduction which produces offspring that are identical to the parent.
