Questions Related to artificial vegetative propagation

Organism produced by asexual reproduction are called

reproduction in angiospermic plants artificial vegetative propagation asexual modes of reproduction common modes of vegetative propagation

  1. clones

  2. offsprings

  3. factors

  4. both (A) and (B)

Show answer
Correct Option: A
Explanation:

Since the organisms produced by asexual reproduction are completely identical to the parents due to no variation, they are called clones.

So, the correct option is  'clones'.

Show answer
Correct Option: D

Assertion: Clones are produced by sexual reproduction and same sexual process.

Reason: These are prepared by group of cells descended from many cells or by inbreeding of a heterozygous line

  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  4. If both the assertion and reason are false

  5. If the assertion is false but reason is true

Show answer
Correct Option: D
Explanation:

Clones are asexually produced. These have same genotype and phenotype like parent.

So, the correct answer is 'If both the assertion and reason are false'

  1. $A-(i), B-(ii), C-(iii), D-(iv)$

  2. $A-(iv), B-(ii), (v), C-(iii), D-(i)$

  3. $A-(ii), B-(v), C-(i), D-(iv)$

  4. $A-(v), B-(ii), (i), C-(iii), D-(iv)$

Show answer
Correct Option: B
Explanation:
 Column I  Column II

 D. Amoeba  (I) Binary fission
   

Correct match following are given in table.

So the correct option is "A-(iv), B-(ii),(v), C-(iii), D-(i)".

The phenomenon observed in some plants where in parts of the sexual apparatus is used for forming embryos without fertilisation is called.

reproduction in angiospermic plants artificial vegetative propagation asexual modes of reproduction common modes of vegetative propagation

  1. Parthenocarpy

  2. Apomixis

  3. Vegetative propagation

  4. Sexual reproduction

Show answer
Correct Option: B
Explanation:

Apomixis is the term given to any phenomenon that leads to formation of embryo wherein parts of the sexual apparatus are used, but without fertilisation. Fertilisation is also absent in vegetative propagation, but parts of sexual apparatus are not involved. An example of apomixis is Citrus.

  1. Spirogyra

  2. Chlamydomonas

  3. Ulothrix

  4. Chara

Show answer
Correct Option: B
Explanation:

A single cup-shaped chloroplast is characteristic of Chlamydomonas. It occupies the major portion of cell and is thick at the base while its sides are relatively thin and projected upward.
