Transcript Types of Asexual Reproduction: (Mitosis)

Types of Asexual Reproduction:
(Mitosis)
BINARY FISSION
paramecium
Parent cell splits producing two equal
sized offspring
Example: Bacteria & Amoeba
Budding
Parent large and offspring small
Example: hydra & yeast
Regeneration
If cut into 2 pieces each piece will be a
new offspring.
Yes
Will they be identical? ____
How can they do this?
They have more undifferentiated cells
than vertebrates do.
Sporulation
Ex. Mold
•A spore is basically a reproductive
cell that can grow into a new cell
through mitotic cell division.
•Spore are stored in special spore
cases until they are ready to be
released.
•If conditions are favorable, they will
grow into new individual cells.
Each spore (offspring) is a clone
Vegetative Propagation
Roots, stems, & leaves are
called vegetative structures.
They normally play a role in
the nutrition & growth of
plants.
When they give rise to a
new plant, the process is
called vegetative
propagation.
Types of Vegetative Propagation:
Natural:
1)Runners
2)Bulbs
3)Tubers
4)Rhizomes
Artificial:
• Cuttings
• Grafting
Runners
Offspring grow from one parent plant
Are they identical to parent plant?
Bulbs
•Onions
•Garlic
•Tulilp
•Daffodil
•hyacinth
Underground stem with fleshy
leaves which store food
Tuber
Underground stem enlarged for
storage of food
Potato, artichoke. Runners, will form with these
Rhizomes
Example:
Irisis &
day lilies
Stems that grow sideways underground.
New plants can grow from these stems.
Cuttings
Vegetative part of a
plant is cut, and it
can develop into a
new plant.
Root Growth
Grafting
A cutting from one plant (scion) is
attached to the main body of a
rooted plant (stock).
ASEXUAL REPRODUCTION
• No sex cells
• No sex organs –
no ovaries or
testes
• Mitosis used
• Offspring are
clones
• No variation
