Cell division is important for life. It is especially important for single-celled species as this is how they reproduce. __________________________ (parents) contribute genetic info via __________________. Sex cells_____________________ to form offspring ______________________________ All offspring ____________ genetically identical to parent ______________________________________ Offspring ________________ genetically identical to parent 1. ___________________________ 4. ___________________________ 2. ___________________________ 5. ___________________________ 3. ___________________________ Parent undergoes ________________________ to produce 2, smaller, genetically identical daughter cells Only ________________________________ (ex. Bacteria), some ________________(ex. Amoebas) and some __________________ use this form of reproduction If Humans Did Asexual Reproduction Benefits to Binary Fission Rapid population __________________________________________ #1 Binary Fission Offspring begins as a _____________________ on parent called a _______________ Bud goes through cell division to _____________________________ before _________________________________ from parent Occurs in _______________________________ and _____________________________ organisms Ex. Hydra If Humans Did Asexual Reproduction #2 Budding Small part of animal _________________________ and grown into new organism Whether _____________________________ grows depends on ___________________________ original parent is contained in ____________________________ Reproduction _________________________________ can’t happen without ________________________________ (ability to regrown body part, organ or tissue) If Humans Did Asexual Reproduction #3 Fragmentation When ____________________ reproduce asexually Some send out: ________________________ A stem that grows _____________________________ along soil surface A runner can grow _______________________________ and become independent Ex. ____________________________________________ Some send out: ________________________ Form from base of trunk or underground stems Ex. ___________________________________________ Some use: _____________________________ Cutting ______________________from some plants will form own _________________________ with roots Other examples include bulbs (____________________) and tubers (_______________________) If Humans Did Asexual Reproduction #4 Vegetative Reproduction - Runners Spores are cells with ___________________________________ Are similar to ___________________ but at are formed through ____________________________ Organisms that form spores may also ___________________________________________________ Ex. _______________________________________ If Humans Did Asexual Reproduction #5 Spore Formation … Asexual Reproduction has the following in common: Only ____________________________ needed to reproduce All offspring are _________________________________ to each other and parent A single organism can produce ______________________________________________ Homework: Textbook p. 60 #2, 4, 5 - 7, 11, 13, 14, 16
