4. Which of the following statements about organelles is NOT true?
A.
B.
C.
D.
Each organelle carries out only one role in the life functions of the cell.

A. Temperature determines eye shape in Drosophila.
B. The optimum temperature for culturing Drosophila is 15 ˚C.
C. Drosophila cultured at 45 ˚C will show a proportionate increase in the number of
compound eye sections.
D. As temperature increases from 15 ˚C to 30 ˚C, the number of compound eye sections in
male Drosophila with bar-eyes decreases.
