IA.  Below are my observations on the external appearance of the indicated species in the plasmolyzed and turgid condition:
 
 

SPECIES	PLASMOLYZED	TURGID
Apium	(2 points)	(2 points)
Helianthus	(2 points)	(2 points)
Coleus	(2 points)	(2 points)
Pelargonium	(2 points)	(2 points)

IB.  I chose to compare the _____ from two of the four species above, since there appeared to be significant differences in the appearance of these plasmolyzed organs between  these two species. (1 point)
 
 

SPECIES	ANATOMICAL OBSERVATIONS	ILLUSTRATIVE IMAGE
	(3 points)	(6 points)
	(3 points)	(6 points)

From these observations, I conclude that the reason the ____ of these species respond differently to plasmolysis is most probably related to the following anatomical differences: ______________(4 points)

II.  Below are  my best images illustrating the indicated "engineering" construction principles that serve to reinforce these various Helianthus organs against the various listed external stresses:
