A) tissue culture grown plants
B) apomicts
C) polyploids
D) vegetatively propagated plants
Correct Answer: A
Solution :
The genetic variability present among cultured cells or plants derived from such cells or progeny of such plants is called somaclonal variation. Generally, the term somaclonal variation is used for genetic variability present among all kinds of cells/plants obtained from cells cultured in vitro. The plant regenerated from cell and tissue culture show heritable variation for both qualitative and quantitative traits. This variation has been used to develop several useful varieties. Apomicts plants are produced by a reproductive process superficially resembles normal sexual reproduction but in which there is no fertilization. Polyploid organism contain nucleus that have more than two sets of chromosomes. Some plants reproduce through parts other than reproductive parts, these plants are called vegetatively propagated plants, e.g., sugarcane.
