Assertion: Totipotency is the ability of explants to give rise while plant. Reason: The cells of explants contain a complete set of genetic information.
1 Both assertion and reason are true but reason is the correct explanation of assertion.
2 Both assertion and reason are true but reason is not the correct explanation of assertion.
3 Assertion is true but reason is false.
4 Both assertion and reason are false.
Explanation:
Tissue culture techniques develop new plants from explants on culture medium. The cells of the explants contain a complete set of genetic information required to produce a new plant. This ability of cells of the explants to produce the new plant is called totipotency.

Assertion: Meristems are the localized regions of active cell division in a plant body. Reason: Somaclones are genetically identical plants.
1 Both assertion and reason are true but reason is the correct explanation of assertion.
2 Both assertion and reason are true but reason is not the correct explanation of assertion.
3 Assertion is true but reason is false.
4 Both assertion and reason are false.
Explanation:
Meristems are the region of rapid cell division in plants. Shoot apices and root apices are some of the examples of meristems. Somaclones are the genetically identical plants produced by micropropagation.

Assertion: Pomato is an intergeneric somatic hybrid. Reason: Cybrids are the somatic hybrids with the nuclear genome from both the parent plants.
1 Both assertion and reason are true but reason is the correct explanation of assertion.
2 Both assertion and reason are true but reason is not the correct explanation of assertion.
3 Assertion is true but reason is false.
4 Both assertion and reason are false.
Explanation:
Pomato is an interspecific hybrid between potato and tomato. Both potato and tomato belong to the same genus ‘Solanum’. Some somatic hybrids have a nuclear genome from one parent and cytoplasmic genes from the other parent. These somatic hybrids are called cybrids.
