Which of the following is not used for vegetative propagation?

evs seed becomes plant introduction to reproduction vegetative reproduction budding, vegetative propagation and spore formation other modes of vegetative propagation the journey of seeds

  1. Bud

  2. Bulbil

  3. Turion

  4. Antherozoid

Show answer
Correct Option: D
Explanation:

In sexually reproduction organisms, the male gamete is called the antherozoid or sperm and the female gamete is known as the egg or ovum. They are not used for vegetative propagation.

So, the correct answer is 'antherozoid'

Which of the following involves the formation of new plants from roots, stems, and leaves?

evs seed becomes plant introduction to reproduction vegetative reproduction budding, vegetative propagation and spore formation other modes of vegetative propagation the journey of seeds

  1. Sexual reproduction

  2. Vegetative reproduction

  3. Layering

  4. None of the above

Show answer
Correct Option: B
Explanation:
Vegetative reproduction involves the formation of new plants from roots, stems, and leaves. It is a form of asexual reproduction of a plant. Only one plant is involved and the offspring is identical to the parent. It mainly involves the mitosis. So, the correct answer is option B.

Which is not a method of vegetative propagation?

evs seed becomes plant introduction to reproduction vegetative reproduction budding, vegetative propagation and spore formation other modes of vegetative propagation the journey of seeds

  1. Micropropagation

  2. Budding

  3. Sowing

  4. Layering

Show answer
Correct Option: C
Explanation:

Vegetative propagation is a form of asexual reproduction of a plant. Here, only one plant is involved and the offspring is the result of one parent. The new plant is genetically identical to the parent.
Micropropagation is the practice of rapidly multiplying stock plant material to produce a large number of progeny plants, using modern tissue culture methods.
Layering is a means of plant propagation, in which a portion of an aerial stem grows roots while still attached to the parent plant and then detaches as an independent plant.
Sowing is to scatter the seeds over the land for growth
So, the correct answer is 'Sowing'

Vegetative propagation does not involve the formation of new plants from old

  1. Roots

  2. Stems

  3. Leaves

  4. Flowers

Show answer
Correct Option: D
Explanation:

Vegetative propagation is a form of asexual reproduction of a plant. Only one plant is involved and the offspring is the result of one parent.
Almost all types of shoots and roots are capable of vegetative propagation, including, stems, basal shoots, tubers, rhizomes, stolons, corms, bulbs, and buds. In a few species, even leaves are involved in vegetative propagation. However, flowers are never involved in vegetative propagation.

Plants have lost their capacity to produce seeds, reproduce by

evs seed becomes plant introduction to reproduction vegetative reproduction budding, vegetative propagation and spore formation other modes of vegetative propagation the journey of seeds

  1. Spores

  2. Vegetative propagation

  3. Fission

  4. Regeneration

Show answer
Correct Option: B
Explanation:

If the plants lose their capacity to produce seed, the plant undergoes asexual reproduction through their vegetative parts like stem, leaf, branch, etc.

So the correct option is 'Vegetative propagation.'

  2. I - D, II - F, III - E, IV - C

  3. I - C, II - B, III - A, IV - D

  4. I - D, II - F, III - A, IV - B

Show answer
Correct Option: A
Explanation:

Ginger is an example of rhizome which is underground modification of the stem. The rhizome grows horizontally to the surface of the soil. 

Onion is an example of bulb in which there are leaves which are placed one above the other in a rosette pattern. This is an underground modification of the stem. 
Potato is an example of tuber. There are eyes which bears adventitious buds which can germinate and develop into new plants. 
Adventitious leaf buds are produced on the notches of Bryophyllum leaf. These adventitious buds can be used for vegetative propagation. The buds can develop into individual plants when favourable conditions are provided. 
Thus, the correct answer is option a. 

Clone is

  1. Descendants of a single parent

  2. Vegetatively produced descendants of a single parent

  3. Sexually produced descendants of a single couple

  4. All the above

Show answer
Correct Option: B
Explanation:

A clone is considered as the vegetatively produced descendants of a single parent because of following reason: 

1) Fusion of gametes does not takes place in vegetative propagation so there is no chance of recombination and variation.
2) The parent cell divides to form daughter cell by mitosis due to which the offspring is genetically identical to the parent.
3) The offspring produced are clones of their parent and have same number of chromosomes.
So, the correct answer is option B.

Clones are individuals obtained through

  1. Self pollination

  2. Cross pollination

  3. Vegetative propagation

  4. Hybridisation

Show answer
Correct Option: C
Explanation:
Vegetatively propagated plants are the clone of their own parents because of the following reasons:
1) Fusion of gametes does not take place in vegetative propagation so there is no chance of recombination and variation.
2) The parent cell divides to form daughter cell by mitosis due to which the offspring are genetically identical to the parent.
3) The offspring produced are clones of their parent and have the same number of chromosomes.
Self-pollination, cross-pollination and hybridization involve fusion of gametes so it can cause recombination and the offspring produced are variants, not the clone.
So, the correct answer is option C.
