Photosynthesis uses energy from the Sun to make sugars such as glucose. What has to happen to the glucose before it can be used
by plant cells? A The glucose combines with another sugar to make usable energy.
B The glucose combines with oxygen to make usable energy.
OC The glucose combines with carbon dioxide to make usable energy.
OD Nothing has to happen to the glucose. Plant cells can use it as is.
Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.
