$(a)$


	
		
			 Hypocotyl 
			Epicotyl
		
		
			$1.$ The portion of the embryonal axis which lies below the cotyledon in a dicot embryo is known as the hypocotyl. 
			The portion of the embryonal cotyledon in a dicot embryo is known as the epicotyl. 
		
		
			$2.$ It terminates with the radicle.
			It terminates with the plumule.
		
	


$(b)$


	
		
			Coleoptile
			Coleoptile
		
		
			 It is a conical protective sheath that encloses the plumule in a monocot seed. It is an undifferentiated sheath that encloses the radicle and the root cap in a monocot seed. 
			It is an undifferentiated sheath that encloses the radicle and the root cap in a monocot seed. 
		
	


$(c)$


	
		
			Integument 
			Testa 
		
		
			It is the outermost covering of an ovule. It provides protection to it. 
			It is the outermost covering of a seed. 
		
	


$(d)$
