Answer:(3)
All cereals like wheat, rice, maize, barley etc. have endospermic or albuminous seeds.
👉In some seeds
such as castor the endosperm formed as a
result of double fertilisation, is a food storing
tissue and called endospermic seeds.
👉In
plants such as bean, gram and pea, the
endosperm is not present in mature seeds
and such seeds are called non-endospermous
👉Generally, monocotyledonous seeds are endospermic but some as in
orchids are non-endospermic.
👉In the seeds of cereals such as maize the
seed coat is membranous and generally fused with the fruit wall. The
endosperm is bulky and stores food.
👉The outer covering of endosperm
separates the embryo by a proteinous layer called aleurone layer. The
embryo is small and situated in a groove at one end of the endosperm. It
consists of one large and shield shaped cotyledon known as scutellum
and a short axis with a plumule and a radicle. The plumule and radicle
are enclosed in sheaths which are called coleoptile and coleorhiza
respectively
👉Fruit: legume; seed: one to many, non-endospermic:pulses (gram, arhar,
sem, moong, soyabean; edible oil (soyabean, groundnut); dye (Indigofera);
fibres (sunhemp); fodder (Sesbania, Trifolium), ornamentals (lupin, sweet
pea); medicine (muliathi).
