Asexual Reproduction Look Ma! No Pa!

Asexual Reproduction Reproduction of organisms by mitosis • Only one parent required • Process is very quick • Offspring are clones - genetically identical • High risk of population collapse Fission Budding Spores Grafting 

Fission Organism splits into two equal sized offspring Protist (Paramecium caudatum) Common in single organisms (like bacteria and protists; the nucleus replicates first then the cytoplasm divides through cytokinesis.

Fission - Sea Anemone Sea anemones are multi-celled organisms that commonly reproduce through fission to form dense colonies of clones

Budding (Hydra sp.) Offspring starts as a growth (bud) on the parent When old enough to survive on its own, bud detaches from parent Bud Mouth Tentacles Foot

Spores Spore cells produced by parent that are specialized for reproduction Each spore contains a nucleus and some cytoplasm Spore will develop into a new organism if it likes where it lands

Grafting Part of a plant is attached to the root system of another plant The two unite to form a new plant containing the roots of one and the stem and leaf structure of the other.
