Select the seeds that have separate endosperm.
(a) Maize (b) Onion (c) Rice (d) Bean
Seeds, which store food materials in their endosperm are called endospermic or albuminous seeds. (e.g., Castor, maize, wheat, barley, grasses, rice, onion).
Seeds, which store food materials in their cotyledons are called non- endospermic or exalbuminous seeds.(e.g., gram, pea, bean, almond, groundnut, mustard, sunflower).
So, the correct answer is 'a, b and c'.
