  1. Flowers

  2. Stem

  3. Fruits

  4. Roots

Show answer
Correct Option: B
Explanation:

The plants like rose, Bougainvillea, Chrysanthemum, grapes, sugarcane, bananas, and cactus, etc. can be grown by means of cuttings. For example, rose plants and chrysanthemums are propagated (or reproduced) by means c cuttings from stems (or shoots) as follows: A piece of stem (or side shoot) having bud is cut from an existing rose plant with the help of a knife. The lower part of this gutting, is buried in moist soil. After a few days, the end of cutting buried in soil develops roots and later on grows to become a new rose plant. 

So, the correct answer is 'Stem'

Which of the following can be reproduced by its stem  ?

  1. Rose

  2. Carrot

  3. Bryophyllum

  4. Papaya

Show answer
Correct Option: A
Explanation:

The plants can be reproduced asexually by the method of vegetative propagation using the parts of the plants. The rose can be propagated by stem cutting. The stem can be cut with a bud and used for the growth of new plants. There are many plants which can be propagated through stem cuttings like sugar cane and guava.

Thus, the correct answer is option A. 

Removal of a small part of plant with a knife is called as

  1. Cutting

  2. Grafting

  3. Layering

  4. All of the above

Show answer
Correct Option: A
Explanation:

A small part of a plant which is removed by making a cut with a sharp knife is called as a 'cutting'. A cutting may be a piece of stem, root or even a leaf. While making a cut, care should be taken to see that there are some buds on it. In this method, a cutting of the parent plant having some buds on it is taken and its lower part is buried in the moist soil. After a few days, the cutting develops roots; shoot, and grows into a new plant. 

During grafting rootstock is generally derived from a plant

  1. Efficient in water and mineral absorption

  2. Resistant to diseases

  3. That grows strong and healthy branches

  4. All of the above

Show answer
Correct Option: D
Explanation:
Grafting is a technique of combining two parts of plants so that they grow together. This allows combining the qualities of a strong, healthy, disease-resistant plant with the qualities of another plant usually one that produces good fruit or attractive flowers. The properties desired to be propagated are obtained from the rootstock, therefore, the plants that undergo this process should be efficient in water and mineral absorption as the rootstocks absorb more water and ions than the self-rooted plants and it must be resistant to diseases and should grow strong and healthy branches.
So, the correct answer is option D.

The fusion of stems of two different plants is seen in the case of

  1. Grafting

  2. Layering

  3. Cutting

  4. All of the above

Show answer
Correct Option: A
Explanation:

Grafting is a method in which the cut stems of two different plants (one with roots and other without roots) are joined together in such a way that the two stems join and grow as a single plant. This new plant will have the characteristics of both the original plants.

Grafting of tissue or organ between individuals of different species is known as

  1. Autograft

  2. Isograft

  3. Xenograft

  4. Allograft

  5. Intergraft

Show answer
Correct Option: C

Some leaves are removed from the stem cutting planted for vegetative propagation. This is done

  1. To increase water uptake

  2. Because it helps in rooting of cutting

  3. To reduce water loss

  4. Because the cutting need less food

Show answer
Correct Option: C
Explanation:

Water is lost through stomata in leaves. If leaves are removed water can be conserved for other physiological processes.
