Which part of an angiosperm seed is triploid (3n) ?
A) embryonic sporophyte generation
B) embryonic gametophyte generation
C) protective seed coat
D) fruit around the seed
E) endosperm
Triploid
An organism or cell having three sets of chromosomes, which is uncommon in most species and often leads to developmental abnormalities.
Angiosperm Seed
The reproductive unit of flowering plants, consisting of an embryo, nutritive tissue, and a protective outer coat.
Endosperm
A tissue in seed plants formed by the union of a sperm with two polar nuclei during fertilization, providing nutrition to the developing embryo.
