in a tobacco plant the male gamete has 24 chromosomes. State the number of chromosomes in 1)egg nucleus 2)zygote 3)endosperm 4)leaf cell. PLEASE GIVE ME EXPLAINATION ALSO!!!!!!!!!!!
In tobacco plant if the male gamete has 24 chromosomes, then-
(i) Number of chromosomes in egg nucleus will be same i.e 24 chromosomes.
(ii)Number of chromosomes in zygote will be 48, as it is formed after fertilization of both male & female gamete.
(iii)Number of chromosomes in Endosperm will be 72 as endosperm is formed after fusion of one sperm nucleus with two egg nucleus.
(iv) Number of chromosomes in leaf cell will be 48. Because leaf cells are diploid
