Question 10
Differentiate between albuminous and non-alburninous seeds, giving one example of each.
Answer
Sexual reproduction among angiosperm plants results in the formation of seeds, inside of fruit. Dissection of seed suggests that it consist of seed coat, cotyledon & embryo axis. Matured seeds are classified into two type based on the reserve food material present in them that is-
1. Non- albuminous
2. Albuminous
Non- albuminous – this type of seed completely consumes the nutritive endosperm during their stages of embryo development. e.g pea & groundnut
Albuminous seed – this type of seed retain or restore some part of endosperm during embryonic development. e.g., maize, barley, castor & sunflower
