Vegetative Propagation

Question 1

Would you expect the daughter plant to be haploid or diploid?
Why?

Answer 1

Diploid

Because of mitosis

Question 2

Give one method,other than runners, and not involving seeds, that is used by horticulturists to produce new plants.

Answer 2

Tissue culturing/ cutting

Question 3

What is meant by vegetative propagation?

Answer 3

Form of asexual reproduction in plants.
Only one plant is required and no gametes or seeds are formed.
A new plant is produced from the root, shoot, leaves or bud of parent plant.

Question 4

Horticulturist use a number of methods to artificially propagate plants. Suggest one.

Answer 4

Plants produced are identical to parent plants so horticulturists knows exactly what is going to be produced

Question 5

Describe two methods used by horticulturists to artificially propagate plants.

Answer 5

CUTTING: a shoot is removed from parent plant? usually treated with root powder and placed in water to develop roots.
GRAFTING: is where shoot of one plant is grafted on to the roots of another plant. Used to combine the best of two plants into one.

Question 6

Give two differences between vegetative propagation and propagation involving seeds.

Answer 6

SEEDS: does not produce identical offspring- always some variation
- ensures seeds are dispersed away from parent plant
Vegetative: offspring will be adjacent to parent plant

Question 7

Give two methods of dispersal to the plant:

Answer 7

Wind or animals

Question 8

Give two advantages of dispersal to the plant

Answer 8

1) New plants are not competing with with parent for limited resources
2) seed dispersal increases chance of survival for the plant

Question 9

What term is used for the type of asexual reproduction that produces the daughter plant?

Answer 9

Vegetative propagation
