bio sexual asexual reproduction

Asexual reproduction

Reproduction without a partner that produces identical offspring (clones)

Binary fission

A type of asexual reproduction where a cell splits into two (e.g.

Budding

A new organism grows from the body of the parent (e.g.

Fragmentation

An organism breaks into parts and each part grows into a new one (e.g.

Spore formation

Reproduction by spores that grow into new organisms (e.g.

Vegetative propagation

Asexual reproduction in plants using parts like roots

Runners

Horizontal stems from which new plants grow (e.g.

Tubers

Swollen underground plant parts that grow into new plants (e.g.

Bulbs

Underground storage organs with new shoots inside (e.g.

Rhizomes

Underground stems that grow horizontally and form new plants (e.g.

Cuttings

A gardening method where a piece of a plant grows into a new one

Layering

A branch is bent to the ground

Grafting

Joining parts of two plants to grow as one with combined qualities

Advantage of asexual reproduction

Faster and only needs one parent

Disadvantage of asexual reproduction

No genetic variation and less adaptability

Advantage of sexual reproduction

More genetic variety which improves adaptability

Disadvantage of sexual reproduction

Slower process and needs two parents

Examples of asexual reproduction

Bacteria (binary fission)

Use of asexual reproduction in gardening

To copy good plant traits and grow plants faster and cheaper

Why identical offspring can be risky

They all react the same to diseases or environmental changes

Why sexual reproduction creates variation

It combines genes from two parents
