Sometimes the potatoes kept in a basket during the late rainy season start giving out small shoots. A comprehensive survey of the literature revealed that most of our current knowledge of these processes concerns exalbuminous seeds, that is, seeds containing a thin residual endosperm layer, and caryopses. Read more: 1. Solution C.3. Define albuminous. The gymnosperms are, therefore, described as naked seeded plants.In angiosperms, on the other hand, the seeds are enclosed within the fruit, … What is the reason for this belief? Bean, Gram, Pea. Allows absorption of water and makes it available to the embryo for germination. Check Answer and Solution for above question from Biology in S (b) _______ is a protective layer of radicle and ________ protects the rolled plumule. Non albuminous seed : Seeds do not retain endosperm as it is completely utilized during embryo development.
