  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. Rubber

  2. Mangoes

  3. Sugarcane

  4. Jasmine

Show answer
Correct Option: C
Explanation:

Vegetative reproduction is a type of asexual reproduction in which new plants are formed from the vegetative parts like, tubers, runners, suckers, rhizomes etc. Some of the plants can be propagated by the means of cutting. The part which is cut is allowed to grow into a new plant. Stem cutting which can be referred as the cane cuttings are used in the case of sugarcane. 

So, the correct answer is option C.
