$14$

Vedclass · Answer

(A) $A-14$. Pollen grains are haploid reproductive cells produced by meiosis,containing $n$ chromosomes. Given that the diploid number of the plant is $2n = 28$,the haploid number is $n = 28 / 2 = 14$. In tissue culture,when pollen grains are cultured to form callus,the cells of the callus retain the same genetic constitution as the pollen grains. Therefore,the cells of the callus will be haploid and contain $14$ chromosomes.
