If the male gamete of an angiosperm contains 14 chromosomes, what will be the number of chromosomes in the aleurone layer and the integument of the ovule, respectively?

Step-by-step solution

The male gamete is a haploid cell ( n ). It is given that n = 14 . The aleurone layer is the outermost proteinaceous layer of the endosperm. Since the endosperm in angiosperms is formed by triple fusion, the aleurone layer is triploid ( 3n ). Its chromosome number will be 3 14 = 42 . The integument is a maternal sporophytic tissue that surrounds the ovule, meaning it is diploid ( 2n ). Its chromosome number will be 2 14 = 28 . Thus, the chromosome numbers in the aleurone layer and the integument are 42 and 28 , res
