Answer:
Photosynthetic lamellae
Explanation:
The cyanobacteria were the first successful photosynthetic cells present on the Earth which were able to convert the light energy into the chemical energy.
The endosymbiosis theory suggested that these cyanobacteria were engulfed by the eukaryotes and the cyanobacteria get transformed into the chloroplast.  
The region of the chloroplast that was formed in the cyanobacteria before the endosymbiosis happened was the photosynthetic lamellae which contained the chlorophyll molecule and thus is the correct answer.
Thus, Photosynthetic lamellae are the correct answer.
 
        
             
        
        
        
Answer:
see if the strips repel each other when brought close together
Explanation:
Electric fields can exert forces on objects, even if the objects involved are not touching. One way to demonstrate that electric fields exist around charged objects is to observe the effects of their forces at a distance. 
Since Ike knows that each strip of tape carries a negative charge, he could see if the strips repel each other when brought close together.
