ASEXUAL REPRODUCTION

Reproduction is the process by which an organism creates

another of its kind

Sexual Reproduction Asexual Reproduction

SEXUAL ASEXUALWith a partner (2

parents)

Alone (1 parent)

Sperm + Egg NO Sperm + Egg

MEIOSIS MITOSIS

Offspring are

genetically different

from parents (mix of

parents)

Offspring are

genetically identical

(clones)

Sexual Reproduction

Asexual Reproduction

Asexual Reproduction

- Fungus

- Bacteria

- Plants (leaves, stems, roots)

- Body Cells (skin, etc.)

- Yeast

There are 5 types of Asexual Reproduction:

1)Binary Fission

2)Budding

3)Spore Formation

4)Regeneration

5)Vegetative Reproduction

BINARY FISSION

- Parent Cell divides into 2 equal parts

(daughter cells)

- Parent Cell doesn’t exist any more.

EX: bacteria

BUDDING- Parent organism divides into 2

inequal parts

- Parent and offspring are not the

same size

- Offspring might stay attached or

break off

SPORE FORMATION- Spores are single-celled

- Spores are formed within a single cell

and then released.

- Spores are the leftovers of the

parent cell.

EX: fungus

REGENERATION

- The ability to re-grow lost or damaged

tissues, organs, or limbs.

EX: worms, starfish, lobsters, etc.

VEGETATIVE

- The new plant is exactly the same

as the parent plant

- Involves roots, stems and seeds.

- Important for nutrition and growth

of plants.

Vegetative Reproduction can be natural (it

happens on its own)

Vegetative Reproduction can be artificial

(humans help!)

BULBS- Short underground

stem with thick

fleshy leaves that

contain stored food

- Each bulb can

become a new plant

TUBERS

- Large underground

stem that contain

stored food

- Like the “eyes” of

potatoes.

RUNNER

- Stems grow over the

soil from the first

stem

- At points along

the runner, new

plants grow

RHizome- Long stems grow

under the soil

- New plants grow

along the stem

- EX: grass,

stinging nettle
