Asexual Reproduction Look Ma! No Pa!
2
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
3
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.
4
Fission - Sea Anemone Sea anemones are multi-celled organisms that commonly reproduce through fission to form dense colonies of clones
6
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
7
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
8
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.
