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.
