Binary Fission► Simplest form► Parent divides into two equal portions.► New cells: DAUGHTER CELLS► Smaller first…grow to normal size► WHO: Bacteria(prokaryotic Mitosis) Protozoa: Ameba and Paramecium
Budding► Parentorganism divide into 2 UNEQUAL parts► New Individuals develop as outgrowths or “buds”► May separate or remain attached.► Who: Yeast and Hydra, Sponges(Porifera) and some Worms.
Spore► Spores: single specialized cells that when released from PARENT CELLS can GERMINATE to form new individuals► Some spores have hard outer covering► Some spores have Flagella► WHO: Fungi, Algae, Protozoa
Tuber►A modified underground stem produced at the tip of a rhizome.► The "eyes" of the potato are actually buds.
Runner► stem that grows sideways along the surface► Strawberry, grass
Rhizome► stem that grows sideways underground► fern, iris, water lilies
Corm► Short, thickened underground stem, usually covered with papery (dry) leaves.► Corms serve as organs of food storage and in some plants ( crocus and gladiolus) of asexual reproduction.► they are often mistaken for bulbs.
ARTIFICIAL VEGETATIVE REPRODUCTION► Techniques to allow plants to be grown with desirable traits.
Plant Cutting► stem, leaf or root: cut and dipped in hormones to encourage growth.► Stem – roses► Leaves – coleus► Root – sweet potato
Plant Layering► stem bent to be covered by soil...covered part forms roots► raspberries, roses.
Plant Grafting► stem or bud from one plant (stock) joined to another part (scion) at the growing regions
