What we will do today

What we will do today

Extend knowledge on asexual reproduction and sexual reproduction

Learn how can animals be cloned

Look at problems with cloning

Slide 3

What are clones?

What are clones?

Genetically

Identical

copies

Slide 4

Hydra budding to make a clone

Hydra budding to make a clone

Slide 5

Asexual Reproduction

Asexual Reproduction

Tiny 'buds' grow out from the hydra's side, develop mouth tentacles, and finally nip off at the base to form a separate individual.

Slide 6

Amoeba dividing asexually

Amoeba dividing asexually

Slide 7

Bacteria dividing asexually

Bacteria dividing asexually

These are CLONES as only have information from 1 parent

Slide 8

Spider plant making asexual clones

Spider plant making asexual clones

Plants retain some

unspecialized cells

These cells have the

potential to grow

into a whole new

plant

Slide 9

Strawberry plants making asexual clones

Strawberry plants making asexual clones

Whole new

plants grow

at the end

of the runners

How is this

Possible?

Slide 10

Sexual reproduction

Sexual reproduction

Information (genes) from 2 parents in the sperm and egg

Slide 11

Sexual Reproduction in Plants

Sexual Reproduction in Plants

Pollen carries genes from the male part of plants this fertilizes the ovule (female sex cell)

POLLEN ovary

containing

OVULE

Slide 12

Sexual reproduction gives variation

Sexual reproduction gives variation

Slide 13

Cloning mammals

Cloning mammals

Sexual reproduction produces variation not clones. Why?

Slide 14

Identical Twins

Identical Twins
