Vedclass · Answer

(A) In ferns,the plant body is a sporophyte $(2n)$,which is diploid.The embryo,including its foot,is a part of the sporophyte generation and is therefore diploid $(2n = 8)$.Spores are produced by meiosis in the sporangia,making them haploid $(n)$.Therefore,the number of chromosomes in the spores will be half the number of chromosomes in the embryo.Calculation: $n = 8 / 2 = 4$.Thus,the correct option is $A$.

If the number of chromosomes in the foot of a fern embryo is $8$,what should be the number of chromosomes in its spores?
