Use the diagram below and your knowledge of the living environment to answer the
questions
11 and 12 which follow. The diagram represents some of the events that take place in a
plant cell.
11. The oxygen and sugar leaving the cell were most likely produced by the processes of
A.
B.
C.
D.
cellular respiration
photohydrolysis
chemiosmosis
photosynthesis
12. The letters X, Y, and Z most likely represent:

B.
C.
D.
