1.Sexual Reproduction in Flowering Plants
medium
An angiospermic leaf carries $16$ chromosomes. The number of chromosomes in its endosperm will be
A
$16$
B
$24$
C
$12$
D
$8$
Solution
A somatic cell (e.g., cell of leaf) contains diploid number of chromosomes. In angiosperms, the endosperm is formed by triple fusion, i.e., fusion of two polar nuclei and second male gamete. Therefore, it is triploid ( $3 n$ ). Hence, the chromosome number in endosperm will be $=24$.
