(a) having no reserve food
(b) being a diploid tissue
(c) its formatting by fusion of secondary nucleus with several spersms
(d) being a haploid tissue
Correct Answer:
being a diploid tissue
Explanation:
Perisperm is remnants of nucellus which is diploid (2n) but endosperm is triploid (3n). Perisperm occurs in the seeds of Black perpper, coffee, castor, cardamum, Nymphaea. Endosperm is the food laden tissue which is meant for nourishing the embryo in seed plants. In angiosperms the endosperm is formed as a result of vegetative fertilization, triple fusion or fusion of a male gamete with diploid secondary nucleus of the central cell.
