Asexual Reproduction

What is asexual reproduction?
}Asexual reproduction is a form of multiplying in plants and animals. 

How does it occur or happen?
}It happens when one parent cell develops another cell which is called its "offspring", this type of reproduction means that it does not need two parents like sexual reproduction where a male & female is required to create offspring.

What are the different types of asexual reproduction in plants & in animals?
}Examples of asexual reproduction in plants are...
  • Fragmentation ~ which is when a piece of a plant such as the branch of a tree or the stem of another plant is replanted in the ground and the plant begins to grow.
  • Binary fission ~ happens when a parent cell splits itself into two daughter cells which are identical and the same shape and size.
  • Budding ~ when a parent cell produces offspring which grows attached to the parent cell until it is mature enough the offspring cell detaches it's cell from the parent cell.
}Examples of asexual reproduction in animals are...
  • Parthenogenesis ~ growth of offspring without the fertilization of sperm from male.
What are the benefits of asexual reproduction for plants & animals?
  • Easier way for farmers to grow their crops when supply and demand is high.
  • Great way to preserve plant and some animal species so they don't become extinct.
