Asexual Reproduction

What type of asexual reproduction is taking place?
Fishermen work hard to catch and remove all the starfish that get into their favorite shell fishing beds and the “underwater farms” where they raise clams and oysters. In the past, they put the starfish into their boats, cut them up with knives, and then throw the pieces of starfish overboard. They thought this would kill the starfish. What they did not know was that each piece of starfish will grow into a whole new animal.

A hydra reproduces when an outgrowth, or bud, forms and continues to develop until if falls off of the parent. This is an example of:

• Binary Fission
• Sporulation
• Budding
• Vegetative Propagation

In asexual reproduction, all of the offspring are:

• Physically Identical
• Genetically Identical
• Physically and Genetically Identical
• Not Identical

This is when a new organism grows by cell division on the body of its parent. The bud, or offspring is identical to the parent. The bud, when large enough, can break off of the parent and live on its own.  Examples of this include yeast, hydra and potatoes.

What is a disadvantage of asexual reproduction?

• The species does not have genetic variation.

• The offspring does not multiply rapidly.
• The offspring does not live for long.
• All of these

What is Binary Fission?

• Develops an outgrowth which is detached from the parent and becomes a new individual.

• The organism produce its own spores. These spores are genetically identical to the parent

• During this type of reproduction the single-celled organism divides in half

• Organisms can be produced from unfertilized eggs

What statement can you make about the spider plant pictured

• It uses sexual reproduction
• It gets its traits from two different plants
• It will not be able to produce offspring
• It contains genes only form the larger plant

What is Regeneration?

• Develops an outgrowth which is detached from the parent and becomes a new individual.

• The organism produce its own spores. These spores are genetically identical to the parent

• When a piece of the parent is cut off or detached, an offspring will grow from the segment.

• A new organism is created from the roots, stems or leaves.

What is Vegetative Propagation?

• The organism produce its own spores. These spores are genetically identical to the parent

• A method of sexual reproduction where the egg and pollen combine.

• A new organism is created from the roots, stems or leaves. Usually involves a "runner".

• Organism develops an outgrowth which is detached from the parent and becomes a new individual.
