Plants
Asexual Reproduction
Requires
only one organism
Offspring will have the same genetic
structure as the parents
Not as complex and requires far less
energy
Organisms that are genetically
identical to their parent are known as
clones.
Rhizomes
Grasses,
cattails and sedges
Produce underground stems or
rhizomes
Buds produce at the nodes
If dies, a new separate plant will
form
Rhizome
Tubers
Modified
rhizomes
Irish potatoes
Specialized stem branches grow
down into the ground and swell with
starch cells
Buds will grow into new plants
Buds are commonly termed “eyes”
Tubers
Runners
Horizontally
growing stems produce
few leaves
The stems run along the ground
Runners can be cut from the parent
plant
Wild strawberry and spider plant
Runners
Cuttings
Vegetative
plants that have been
removed and rooted in soil or other
suitable material
Made from stems, roots or leaves
Geranium, Coleus, African violet
Cuttings
Bulbs
Onions,
chives and lilies
Very short stem surrounded by
fleshy leaves
In the spring the shoot apex begins
to grow using the nutrients stored in
the leaves
Bulbs
Corms
Similar
to bulbs except that there are
no storage leaves
Nutrients are stored in the swollen
stem
Corms
Cell Culture
Sometimes
just one cell can
regenerate into an entire plant
One cell from a carrot taproot is put
into a tube of water with plant
nutrients
The one cell divides and forms a
bunch of cells
The small carrot plant will from into a
carrot identical to the carrot from
which the one cell came
Cell Culture
Tissue Culture
Engineered
cells of plants
Petunias, tobacco and tomatoes
Place the engineered cell in an
environment with special hormones
and nutrients that encourage growth
Tissue culture will form leaves and
roots and finally and entire plant will
grow.
