A study of chloroplast and chlorophyll concentration in different sections of a leaf revealed a strong positive correlation between chloroplast concentration and chlorophyll concentration in each section of the leaf. Why would this be considered a reasonable finding?
1) because the same method is used to quantify both chlorophyll and chloroplasts
2) because the same reagent is used to extract both chlorophyll and chloroplasts
3) because both chlorophyll and chloroplasts are distributed evenly in all sections of a leaf
4) because chlorophyll is found within chloroplasts
