Asexual Reproduction Uses ONLY 1 source of DNA

Asexual Reproduction Uses ONLY 1 source of DNA Offspring are IDENTICAL to parents

Asexual Reproduction that uses ONLY 1 source of DNA Offspring (babies) are genetically IDENTICAL to the parent MITOSIS is a form of ASEXUAL reproduction

Types of Asexual Reproduction Binary Fission Budding Spore Formation Regeneration Vegetative Propagation

Binary Fission 1. Parent Cell 3. Cytoplasm Divides 2. Nucleus Divides 4. Two Daughter Cells Are the offspring DIFFERENT from or IDENTICAL to the parent? WHY? ?

Budding A smaller version grows off the side of the parent When fully developed (but still SMALLER than parent) it will fall off and grow to adult size Hydra, Yeast

Hydra Budding 1. Bud forms on side of parent 2. Bud develops and matures 3. When fully developed, Bud falls off 4. Seperate bud grows to full size

Spore Formation Small packets of DNA are released from the parent. Wherever the spore lands, a new offspring grows Molds and Fungi use this method

Spore Formation Also called Sporulation

Regeneration When a piece of the parent breaks off and grows into a new organism Parent regrows lost part Starfish, Lizards, Newts

Regeneration

Sexual Reproduction in Plants can reproduce SEXUALLY or ASEXUALLY Plants have reproductive parts – when pollen and egg combine that is SEXUAL reproduction (2 sources of DNA – pollen & egg)

Vegetative Propagation When the NON reproductive parts of a plant (stems, leaves, etc. ) grow new offspring…this is ASEXUAL reproduction All the DNA is coming from the leaf or stem cell that is dividing

Are the offspring INDENTICAL to or DIFFERENT from the parent? WHY?
