1. Asexual
Reproduction

2. Reproduction
• Reproduction is the capacity of
all living things to give rise to new
living things.
• includes the transmission of
hereditary material from the
parent/parents.
• two types
– asexual beginning
– sexual.

3. Asexual Reproduction
Basics
 Is the simplest form of reproduction
 Occurs in plants, simple
animals, bacteria, and protists
 Requires one parent
 Is more reliable than sexual
reproduction
 Doesn’t allow for any type of genetic
variation

4. The 6 types
Sporulation
Fragmentation
Regeneration
Binary Fission
Budding
Vegetative propagation

5. Sporulation
Uses spores
spore is a reproductive cell that
produces a new organism
Spores are unicellular
If conditions are right a spore will
develop into a new individual
They can be carried by the
wind, water, or animals

6. Fragmentation
When a organism is broken into more
than one part
Organism must have good regeneration
abilities
Create many new organisms quickly

7. Regeneration
An organism can replace/re-grow an
injured or lost part
Regeneration in plants from
Roots
Stem
leaf
Regeneration in animals
For simple organisms
No vertebrates have this power
Examples are starfish and the salamander

8. Binary Fission
One parent dividing into two by
mitosis
Offspring are always genetically
identical
Cells may stay close together to
form filaments or colonies
Examples-Bacteria and Amoebas

9. Budding
Form on part of the parent by
growing an outgrowth which then
detaches
Example- is Hydra and Yeast
Offspring will always be genetically
identical to the parent

10. Vegetative Propagation
Plant parts make new plant
Reproduction is very quick
Disadvantage: many plants grow
close to each other
1. Bulbs
– Underground stem
– Surrounded by colorless leaves
– Colorless leaves protect the bulb
– The green leaves store the food

11. 2. Rhizomes
– Underground stem
– They store food for new plant
– At the end of Rhizomes nodes form
3. Runners/Stolon (strawberries)
– They are above ground.
– Stems
– Nodes form at the end of Runners
– They grow outward

12. 4. Tuber (potatoes)
– Underground stem
– Stores food
– The nodes eat the tuber
– Potatoes have eyes / buds to make new
tubers and or reproduce
5. Grafting
– Surgically connecting two similar plants
– Ex. Apples
– Not done naturally

13. 6. Cutting
– Cutting off a stem or leaf to reproduce a
new plant
– Must be in wet or moist area
– Combination of regeneration and
fragmentation
– Not done naturally
7. Stolon
