Types of Asexual Reproduction

Types of Asexual Reproduction
2
You should know...

• Asexual reproduction is the formation of a new
  individual that has the same genetic information
  as its parent.
• The individual is a clone, or an exact copy, of
  its parent.

3
You should know...

• Asexual reproduction occurs in one-celled
  organisms such as bacteria and in multicellular
  organisms such as plants and some animals.

.

• There are several different types of
• asexual reproduction

1. Binary Fission

1. Binary Fission

• A single parent cell replicates its genetic
  material and divides into two equal parts.
• B.F. is only used by single-celled organisms such
  as amoebas, and bacteria.

2. Budding

• Some very simple multicellular organisms can
  reproduce asexually using this method.
• Budding is when an outgrowth or bud grows off
  of the parent .
• The outgrowth is identical to the parent and may
  stay attached or detach and become a separate
  individual organism.

• Budding is used by sponges, hydras and
  unicellular yeasts.

3. Fragmentation

• With fragmentation any part of an organism that
  breaks off can re-grow into a clone of the
  parent.
• Organisms that can do this include the sea star
  (animal) and Eurasian milfoil (plant).

• Other plants that can reproduce this way are
  mosses and liverworts.

4. Vegetative Reproduction

• Done only by plants. (like, thats why its
  called vegetative)
• The stem or root of a plant will divide
  repeatedly until they develop into a plant
  identical to the parent plant.

4. Vegetative Reproduction

• Examples are strawberry stem runners,

4. Vegetative Reproduction

• Examples are strawberry stem runners, potato
  sprouts or eyes

4. Vegetative Reproduction

• Examples are strawberry stem runners, potato
  sprouts or eyes, and tulip, daffodil and
  hyacinth bulbs.

5. Spores
25
5. Spores

• A spore is a reproductive cell that grows into a
  new individual by mitosis.
• Spores are very light so they can be easily
  carried away from the parent organism by wind or
  water.
• If the conditions are good the spore will grow
  wherever it lands.

• Grafting is when part of one plant is stuck onto
  another plant.

• The top part is called the scion.
• The root part is called the stock.
