Asexual Reproduction

• Asexual Reproduction is a result of Meiotic Cell
  Division.
• Parent cells divide into two identical daughter
  cells.
• In Asexual reproduction the offspring are
  genetically identical to the original.
• In Asexual Reproduction there are no fusing off
  cells.
• Unicellular Plants And Multi-cellular Plants can
  reproduce both sexually and asexually.
• Asexual Reproduction is not as complex and
  requires far less energy.
• Different Types of asexual reproduction are
  Binary Fission, Budding, Sporulation,
  Regeneration, Vegetative Propagation and Cloning.

3
Binary Fission

• Simplest type of asexual reproduction.
• Binary Fission involves a one celled organism.
• Binary Fission produces new daughter cells.
• Binary Fission begins with DNA but doesnt
  exchange genetic info.
• The cells become an exact replication of each
  other.

4
Budding

• This is when a child grows out of the parent.
• Hydras and yeast are examples of budding.
• When the cell splits off the nucleus divides
  equally but its cytoplasm divides unequally.
• The parent and child could stay connected and
  form a colony or separate.

5
Sporulation

• Spores contain a nucleus and a small amount
  cytoplasm.
• Sporulation sprouts out of decaying materials
  releasing spores to make more sprouts.
• Some examples are bread mold, mushrooms, mosses
  and ferns.

6
Regeneration

• Development of a new organism from a peace of a
  new parent.
• Also helps with replacement of body parts.
• Some examples of regeneration are sponges and
  plantaria.
• So if a starfish gets a leg torn off it can be
  made into a new starfish.

7
Vegetative Propagation

• It is when a part of a plant grows into a new
  plant.
• Everything but seed reproduction is considered
  vegetative propagation.
• Vegetative propagation can occur naturally or
  unnaturally.
• Types of natural vegetative propagation are
  tubers, runner, rhizomes and bulbs.
• Types of unnatural vegetative propagation are
  cuttings and grafting.

8
Vegetative Propagation

• Runners
• Stems grow on top and across the ground from the
  existing stem.
• From the runner new plants grow
• Some examples are strawberries and some grasses.
• Bulbs
• Underground stems for food storage
• Food stored in large leafs
• Each bulb develops into a new plant.
• One example of bulbs are onions.

9
Vegetative Propagation

• Tubers
• Underground stems that contain stored food.
• The eyes of potato can develop into new plants.
• Potato are one example of tubers.
• Rhizomes
• Long modified stems that grow horizontally under
  the ground.
• New plants grow off the roots.
• Long grasses, ferns, and irises are examples of
  rhizomes.

10
Vegetative Propagation

• Cuttings
• Pieces of a root or stem that in certain
  conditions are made into new plants.
• Some examples are bananas, roses and sugar cane
• Grafting
• Taking a part of a plant and connecting it to
  another one.
• Combining the two plants.
• Some examples are seedless oranges and grapes.
