Asexual

Single parent
The offsprings are clones to the parent
Does not involve the fusion of sex cells

1

Types of asexual reproduction

Fission (binary fission)
Budding
Fragmentation
Vegetative propagation

2

Fission

Also known as binary fission
- prokaryotic organisms like bacteria use this method to produce
- some eukaryotic single celled organisms use like amoeba
- copies off of circular chromosome and splits in half

3

Budding

Uses mitosis to copy cells
- genetically the same as parents
- new idividuak growing off the side of parent
- spores can form through budding

4

Spores

Can be formed in clumps or chains
Can be eukaryotic or prokaryotic
Spores are a way of surviving unfavorable environment changes
They are produced asexually

5

Fragmentation

Also known as regeneration
Occurs in multicellular organisms
- body of parent breaks into 2 or more parts
MITOSIS (eukaryotic

6

Vegetative propagation

By MITOSIS
CUTTING: separation of part of one plant to form a new plant
Lateral buds may be above the ground of below

7

Grafting

Cut off branch of different tree onto another three
Eventually xylem will join together
By MITOSIS

8

Runners

Individual plants grow from lateral buds eg. Strawberry tree ABOVE THE SURFACE

9

Rhizomes

Below surface
Flowers, bulbs, potatoes

10

Advantages of Assexual

- rapid increase in population
- ensures "ideal" feature are preserved from generation to generation

11

Disadvantages of asexual

- increased competition for resources
- lack of genetic variation to withstand change of events
