Hi, I have done some questions and was wondering if someone would not mind having a look over them. I have answered them to my best ability. Hope they are not all wrong! 🙂
Thanks a million.

1Many fruits and vegetables are genetically identical.

A ) state one way in which plants forming such fruits and vegetables are produced.
B) state two advantages of producing plants in this way 

Ans
1a. A specialised part of the plant separates from the parent and grows by mitosis to form a new plant.

Ans 
1b The offspring formed in this way are genetically identical with the parent.

2a In relation to flowering plants,
Explain what is meant by vegetative propagation.

2b Clones are genetically identical individuals. Are the products of vegetative propagation clones? Explain your answer. 

Ans 
2a is asexual reproduction in plants.
An example of natural vegetative propagation that involve the stem are buttercups.
Runners are horizontal stems that run or grow above ground and from which new plants grow.buds are formed at each node and may give rise to a new plant with its own root system

Ans 
2b  Yes as a specialised part of the plant separates from the parent and grows by mitosis to form a new plant. The offspring formed in this way are genetically identical with the parent.

3. Give three reasons why seed reproduction is more complex than vegetative reproduction

Ans; depend on outside agents. Eg pollination and dispersal
Slow growth of the young plants to maturity
Wasteful( petals, nectar, pollen, fruit)

Explain why seed-grown plants often show more resistance to disease than plants that arise from vegetative propagation.

Ans;  the offspring possesses variation and this assists plants to survive in a habitat by being better adapted. The seedlings may be resistant to a pathogen or be able to survive if climate conditions change.

Suggest a biological reason for each of the following.

A) growing plants from cuttings rather than from seeds

Ans; to form new leaves and roots quickly

B) removing leaves from a cutting before planting it in soil

Ans; to reduce water loss 

C) using growth regulators when growing cuttings

Ans;  to speed up root formation

D) grafting cultivated roses onto wild rose rootstock

Ans; to combine the useful traits or qualities from the roses onto wild rose rootstock, eg large flowers grafted to wild rose with large roots but with small insignificant flowers

E) cherry blossom trees may have white flowers on some branches and pink flowers in other branches

Ans;  the offspring possess variations 

F) growing plants by micropropagation

Ans;) to produce large number of plants from small plant pieces. 

G) plants that reproduce vegetatively  in nature may become overcrowded.

Ans;) cos they reproduce rapidly
