Select the mismatched pair of organism and its mode of multiplication.

  1. Organism - Agave, Oxalis; Mode of multiplication - Bulbils

  2. Organism - Amoeba, Paramecium; Mode of multiplication - Binary fission

  3. Organism - Chlamydomonas, Ulothrix; Mode of multiplication - Sporangiospores

  4. Organism - Adiantum ; Mode of multiplication - Adventitious buds present at leaf tips
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sporangiospores are non-motile spores produced inside the sporangia. They are generally dispersed by wind and germinate to produce new mycelium (e.g., Rhizopus, Mucor, etc.) In Chlamydomonas and Ulothrix, zoospores are formed.

So, the correct answer is 'Organism - Chlamydomonas, Ulothrix; Mode of multiplication - Sporangiospores'.

Vegetative propagation is the term used for

  1. Sexual reproduction in animals

  2. Sexual reproduction in plants

  3. Asexual reproduction in animals

  4. Asexual reproduction in plants
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Vegetative propagation (vegetative reproduction) is the formation of new plants from vegetative units such as buds, tubers, rhizomes, etc. This term is used for asexual reproduction in plants. Plants with reduced power of sexual reproduction, long dormant period of seed or poor viability are multiplied easily through vegetative propagation.
So, the correct answer is 'Asexual reproduction in plants'.

Which of the following is not used for vegetative propagation?

  1. Bud

  2. Bulbil

  3. Turion

  4. Antherozoid
Reveal answer Fill a bubble to check yourself
D Correct answer
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'

A Correct answer
Explanation

Vegetative propagation is a form of asexual reproduction in plants where a new individual develops from a fragment or part of the parent plant.

Vegetative reproduction by layering is found in:

  1. jasmine

  2. mango

  3. rose

  4. All of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Layering is a common method of vegetative propagation used for plants like jasmine, where a stem is bent to the ground to encourage root growth.

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

  1. Sexual reproduction

  2. Vegetative reproduction

  3. Layering

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
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?

  1. Micropropagation

  2. Budding

  3. Sowing

  4. Layering
Reveal answer Fill a bubble to check yourself
C Correct answer
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
Reveal answer Fill a bubble to check yourself
D Correct answer
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

  1. Spores

  2. Vegetative propagation

  3. Fission

  4. Regeneration
Reveal answer Fill a bubble to check yourself
B Correct answer
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.'

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

  4. I - D, II - F, III - A, IV - B
Reveal answer Fill a bubble to check yourself
A Correct answer
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.
