  • question_answer What would be the number of chromosomes in the cells of the aleurone layer in a plant species with 8 chromosomes in its synergids?

    A)  16     

    B)  24     

    C)  32     

    D)  8

    Correct Answer: B

    Solution :

     Synergids are two, short-lived, haploid cells lying close to the egg in mature embryo sac of flowering plant ovule, while the endosperm is a triploid tissue formed after triple fusion. Thus, if the synergids have 8 chromosomes, the aleurone layer (part of endosperm) will have just triple of that of chromosomes in the synergids, i.e., 24 chromosomes.
