Question

Some angiosperm seeds are said to be ‘albuminous’, whereas few others are said to have a perisperm. Explain each with the help of an example.

Answer 1

Albuminous seeds are those which retain a part of endosperm as it is not completely used up during embryo development. For example, in wheat and maize. In some seeds remnants of nucellus are also persistent. This residual, persistent nucellus is the perisperm. For example, in black pepper and beet.
