Question

Select the correct answer from each drop-down menu.

During the day, plants produce ___________
by splitting water molecules in the light-dependent reactions of photosynthesis. At the
same time, plants use cellular respiration to produce some of the __________
needed by the light-Independent reactions to make
sugars. During the night, plants produce __________
because _______takes
place.

Answer 1

During the day, plants produce (oxygen) by splitting water molecules in the light-dependent reactions of photosynthesis.

At the same time, plants use cellular respiration to produce some of the (carbon dioxide) needed by the light-independent reactions to make sugars.

During the night, plants produce (carbon dioxide, but not oxygen) because (only cellular respiration) takes place.
