1. Types of Asexual Reproduction 3/17/2008

2. Do Now: MeiosisMitosis Forms sex cells (sperm and eggs) ½ the number of chromosomes compared to the parent cell Genetically identical to parent cell Responsible for growth, differentiation, and asexual reproduction One replication and two divisions One replication and one division 4 daughter cells formed 2 daughter cells formed

3. Asexual Reproduction Involves the process of Offspring are genetically to parent mitosis identical

4. Binary Fission Parent divides into halves after nucleus replicates No parent remains  daughter cells grow to normal size Occurs in,, and 2 equal 2 bacteriaprotozoa algae

7. Budding Parent organism divides into halves Daughter cell forms from outgrowth or off parent Buds may or remain attached and form a 2 unequal bud break off colony

11. Sporulation (spore forming) Production of many in a special spore producing structure ( ) Spores are, specialized cells, containing and within a hard case Occurs in,, and spores spore case microscopic nucleuscytoplasm moldsmushrooms ferns

14. Regeneration Ability to back missing parts The more the organism, the it is to regenerate Occurs in simple organisms such as and grow complex harder starfishflat worm

18. Vegetative Propagation of a body of a multicellular organism gives rise to a organism Common in - using stems, leaves, or roots Can occur or piece new plants naturallyartificially

19. Natural Vegetative Propagation Bulb- Corm- Tuber- Runner- Rhizome- Short underground stem with stored food & fleshy leaves Ex. Onion, tulip Short underground stem with stored food Ex. Water chestnut Enlarged underground stem Ex. potato (stolon) horizontal stem with buds along ground’s surface Ex. strawberry Underground horizontal stem Ex. ginger

20. Tuber Bulb Corm Rhizome Runner

21. Artificial Vegetative Propagation Cutting- use of plant to reproduce (Ex. ) Layering- stem is over and covered with  will root and form plant (Ex. ) Grafting- stem or bud of one plant is to another plant (Ex. ) part Spider plant bent soil newraspberry joined Seedless fruit tree permanently
