        	 2.	 An	investigation	is	carried	out	by	a	group	of	pupils	on	two	similar	plants.	The	observation	on
       CS 4.1  this	plant	is	made.
       CS 4.2
                                Table	1
                  Plant        Condition	of	plant


                   A       •	 The	leaves	are	greener	in
                             colour
                           •	 More	leaves
                           •	 More	roots


                   B       •	 The	 leaves	 are	 green	 in
                             colour
                           •	 Fewer	leaves                            A	            B
                           •	 Lesser	roots                               Diagram	2

             (a)	 Write	one	observation	and	inference	based	on	the	results	in	Table	1.

                 Observation:


                 Inference:


             (b)	 What	parts	of	the	plants	are	involved	in	responses	to	stimuli?





             (c)	 Give	a	hypothesis	for	this	investigation.








             (d)	 Why	do	plants	need	to	respond	to	stimuli?





             (e)	 State	four	needs	of	plants	to	carry	out	the	photosynthesis	process.





                                                                                            Gamified
