A leaf makes glucose in the light. What does the plant do with the part of that glucose it neither stores nor builds into structures?

It respires the glucose to release energy for its life processesПравильный ответ
It passes the glucose back out through the stomata as a gas
It saves the glucose until dark, because it can only respire at night
It converts the glucose into chlorophyll to keep its leaves green

Объяснение

Respiration breaks the sugar down and transfers the energy held in it to the plant's activities, and this goes on while the leaf is lit as well as after dark. The tempting alternative is that the sugar is held back for the night, but a plant needs energy continuously and draws on its sugar whenever that need arises.
