Asexual Reproduction Asexual reproduction is a method of reproduction with all the genetic information coming from one parent.
Asexual Reproduction • Asexual reproduction is the formation of new individuals from the cell(s) of a single parent. • HAPPENS BY MITOSIS ONLY • It is very common in plants; less so in nimals
• Did I tell you asexual reproduction only involves MITOSIS? ? ?
Asexual reproduction is sometimes called cloning. Cloning is the production of identical genetic copies. All forms of asexual reproduction are variations of the cell division process of mitosis. Mitosis is associated with asexual reproduction, as well as growth and repair in sexually reproducing organisms. Mitosis
Types/Methods of Asexual Reproduction • 1. binary fission -- involves an equal division of both the organism cytoplasm and nucleus to form two identical organisms -- the diagram of the protist at the right is example of this • Bacteria
Budding • Here, offspring develop as a growth on the body of the parent. -- the diagram of a yeast at the right is an example of this
Sporulation • sporulation (spore formation) -- is reproduction involving specialized single cells coming from one parent – • Ex. , mold spores
Bread Mold
Sporulation
Vegetative propagation in Plants • A plant body part/organ can be used for to make the whole plant. • Like a stem
Stems • In some species, stems arch over and take root at their tips, forming new plants. • The horizontal aboveground stems (called stolons) of the strawberry (shown here) produce new daughter plants at alternate nodes.
• Other part is: • Leaves •
Leaves • This photo shows the leaves of the common ornamental plant Bryophyllum (also called Kalanchoë). Mitosis at meristems along the leaf margins produce tiny plantlets that fall off and can take up an independent existence.
Roots • Some plants use their roots for asexual reproduction. • The dandelion is a common example. Trees, such as the poplar or aspen, send up new stems from their roots. • In time, an entire grove of trees may form — all part of a clone of the original tree
CLONE
REGENERATION • Where you can grow a body part or a whole new organism
