Asexual Reproduction

Sexual & Asexual Reproduction Sexual Reproduction § Involves two cell/organisms and the exchange of genetic information Asexual Reproduction § Involves one cell/organism and does not involve the exchange of genetic information

Types of Asexual Reproduction 1) Binary Fission § Cell/organism splits into two cells/organisms § Example: bacteria

Types of Asexual Reproduction 2) Budding § the new cell/organism grows out from the original cell/organism § Example: hydra

Types of Asexual Rreproduction 3) Fragmentation § The new cell/organism splits off of the original cell/organism § Example: starfish

Fragmentation

Types of Asexual Reproduction 4) Spores § Spores are produced and develop into new organisms § Spores can survive after the parent cell dies § Examples: Ferns

Types of Asexual Reproduction 5) Vegetative Propagation § New organisms are produced from runners § Example: spider plants

Outline Asexual Reproduction Regeneration and Stem Cells Cloning Cancer

Regeneration & Stem Cells § The ability to regrow a tissue, an organ, or a part of the body § Occurs through mitosis § Fragmentation results from regeneration

Regeneration & Stem Cells § Some organisms can regenerate entire components of their structure § This type of regeneration occurs through stem cells § A stem cell is a non-specialized cell (can become any type of cell in the organism)

Regeneration & Stem Cells § More complicated organisms cannot regenerate entire structures but they can regenerate tissues § This is because the cells have become specialized § Examples: Cardiac tissue, neurons, liver tissue

Cloning § Cloning is the process of producing identical offspring from a single cell or tissue § Clones are identical to the parent organism

Cloning § Cloning is a natural process (in some organisms) § All forms of asexual reproduction produce clones § Cloning in organisms that reproduce sexually is not natural
