What is the difference between albuminous and exalbuminous seeds?
Albuminous seeds are the seeds which have food stored in the special nourishing tissue called as endosperm that remains persistent till maturity. Cotyledons only act as food sucking organs and not food storage organs.e.g. Castor seed.
Exalbuminous seeds are the seeds which have the stored food and the cotyledons in a special structure called as kernel. It does not remain until the embryo is mature. e.g. Pea seed.
