Vedclass · Answer

(B) The correct answer is $B$. Many plant species,including those in the families $Leguminosae$,$Malvaceae$,$Chenopodiaceae$,$Convolvulaceae$,and $Solanaceae$,possess very hard seed coats. These seed coats are impermeable to water and oxygen,which prevents the embryo from imbibing water and initiating germination. This physical barrier is a primary cause of seed dormancy in these legumes,requiring specific environmental conditions or mechanical/chemical scarification to break the dormancy.
