6.4 Cloning

Question 1

How are plants cloned? 2

Answer 1

By taking cuttings and growing them

Taking small groups of cells from part of a plant and growing them (tissue culture) much more difficult than cuttings.

Question 2

How are animals cloned?

Answer 2

A developing embryo with unspecialized cells is splint into smaller groups of cells. Each group of genetically identical cells is transplanted and allowed to develop in a host animal. Difficult and expensive.

Question 3

What two things can animals be cloned from

Answer 3

Multiply offspring can be made from one embryo

Adult cells can be cloned

Question 4

What is a host animal?

Answer 4

One into which an embrio is transfered to develope.

Question 5

What are natural clones?

Answer 5

identical twins

Question 6

In what way are embryo transplants in cloning similar to what happens when identical twins form?

Answer 6

For twins a single embryo starts developing and then splits naturally into two. In cloning the embryo is split artificially and then transplanted into a host animal
