Answer 1

The correct option is C 1 2 3 4 5

d c e b a
Totipotency
Totipotency is the capacity of a cell to differentiate into any cell type, making it capable of generating or developing into an entire organism. Each plant cell is a totipotent cell that is capable of producing a whole plant.
In tissue culture a part of the desired plant called explant having totipotency is taken and aseptically introduced into nutrient media.
So the correct pair is “totipotency- capacity to generate a whole plant from an explant”

Micropropagation
Micropropagation is an $invitro$ technique that uses tissue culture for the commercial production of plantlets. As a result of micropropagation large amounts of high quality plants can be produced in a short duration of time. Usually plants that have a high commercial value are grown using this method.
So the correct pair is “Micropropagation- producing large number of plants through tissue culture”

Somaclone
Somaclones are genetically identical plants produced by tissue culture of somatic plant cells, tissues or organs.
So the correct pair is “Somaclone-Plants genetically identical to original

Somatic hybrid
Somatic hybrids are the hybrid plants produced by the fusion of protoplasts of somatic cells obtained from plants belonging to different species.
So the correct pair is “Somatic hybrid- plant grown from hybrid protoplast

Biofortification
Biofortification is a process by which the nutritional quality of food crops are enhanced using conventional breeding methods.
So the correct pair is “Biofortification- Breeding crops with higher levels of nutrients”
