Transcript of "Asexual mode of reproduction"

  1. 1. LIVING IN ORGANISMS
  2. 2.  Used by many unicellular organisms, plants, and lower animals.  Involves only mitotic cell division = each offspring has exactly the same heredity as its parent.  Usually rapid compared to sexual reproduction. Types of Asexual Reproduction Include:
  3. 3. 1. 2. 3. 4. 5. BINARY FISSION BUDDING SPORE FORMATION REGENERATION VEGETATIVE PROPOGATION NATURAL ARTIFICIAL
  4. 4.    Nucleus of parent cell replicates and the parent cell divides in 2 Equal halves . No parent remains The 2 daughter cells grow to normal size individual. Occurs in Algae, Bacteria and Protozoa. ,
  5. 5.  Parent organism divides into 2 Unequal halves.  Daughter cell forms from outgrowth grow as an independent individual.  The outgrowth is known as BUD.  Buds may breakoff or remain attached and form a Colony.
  6. 6. hydra yeast
  7. 7.  Production of many spores in a special spore producing structure ( spore case)  Spores are microscopic, specialized cells, containing nucleus and cytoplasm.  Nucleus is close within a hard case.  Occurs in molds , ferns and mushrooms.
  8. 8. Ability to grow back missing parts.  More the organism is complete harder to grow the missing parts. Occurs in simple organisms such as --- flat worm  starfish and
  9. 9. Development of a new plant from the vegetative part of a plant.   Common in plants- using stems, leaves, or roots. Can occur naturally or artificially.
  10. 10.      Bulb- Short underground stem with stored food & fleshy leaves Ex. Onion, tulip Corm- Short underground stem with stored food Ex. Water chestnut Tuber-Enlarged underground stem Ex. potato Runner-(stolon) horizontal stem with buds along ground’s surface Ex. strawberry Rhizome-Underground horizontal stem Ex. ginger
  11. 11. Runner  Bulb Bulb Rhizome Corm
  12. 12. Cutting- use partof plant to reproduce (Ex.Spider plant )    Layering- stem is bentover and covered with soil  will root and form new plant (Ex. raspberry ) Grafting- stem or bud of one plant is joined to another plant permanently (Ex. Seedless fruit tree )
