Answer 1

Cryptogams and phanerogams are two sub-kingdoms of the kingdom Plantae. Cryptogams consist of seedless plants and plant-like organisms whereas phanerogams consist of seed-bearing plants. Cryptogams do not develop flowers and fruits as well. Most Cryptogams do not have a vascular system.

Answer 2

The new variety is a pure line. The new variety is highly uniform, genetic variation is very less. Pure line variety is expected to have a narrower adaptation and lower stability in performance as there is less genetic variation. The variety is easily identified in seed certification programmes.
