Cloning

Question 1

What 2 things can plants be cloned from

Answer 1

Tissue culture
Cutting

Question 2

What is tissue culture

Answer 2

Using small groups of cells from a part of a plant to grow identical new plants

Question 3

Why is using tissue culture beneficial

Answer 3

Preserves rare plant species
Used by plant nurseries to produce lots of stock quickly

Question 4

What are cuttings

Answer 4

Older but simple way of cloning
Used by gardeners to produce many identical new plants from cutting out a piece of plant
Quick and cheap

Question 5

What are embryos transplants

Answer 5

Splitting apart cells from a developing animal embryo before they become specialised, then transplanting the identical embryos into host mothers

Question 6

What are the steps of adult cell cloning

Answer 6

Take unfertilised egg cell and remove its nucleus
The nucleus from an adult body cell is inserted into the egg cell
An electric shock stimulates the egg cell to divide to form an embryo
These embryo cells contain the same genetic information as the adult skin cell
When the embryo has developed into a ball of cells, it is inserted into the womb of an adult female to continue to develop
