Asexual Reproduction

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.

Asexual reproduction in plants can occur through bud formation, fragmentation or spore formation.

Bud formation / 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.

Bud formation / Vegetative

Propagation Stolons

• Stems grow on top and across the

ground from the existing stem.

• From the stolons 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.

Bud formation / Vegetative

Propagation

Tubers • Underground stems that contain

stored food.

• The eyes of potato can develop

into new plants.

• Potato are one example of tubers.

Fragmentation

Cuttings • Pieces of a root or stem that in

certain conditions are made into

new plants.

• Some examples are bananas, roses

and sugar cane

Spores

• The new plant is created from

a fragment of the mother

plant.

• This process is often used with

a cutting in gardering.
