9.  PROVIDE SUPPORTING EVIDENCE:
Infer why chloroplasts are found mostly in the leaves of plants.
a. The large surface area of leaves allows for maximum light absorption.
b. The waxy coating on the surface of leaves helps prevent evaporation.
c. Chlorophyll interferes with the xylem and phloem in the stems and trunks of plants.
d. The large surface area of leaves allows for contact with oxygen.
-________________________________________
Light is absorbed by the chloroplasts in plant cells
-Large surface area provides more exposure of cells
