Question

if you do an experiment where before you start your experiment you keep a green plant in the dark for six hours. once you start the experiment you expose it to RED light for 1 hour. so once we start the experiment would both light and dark reactions proceed as normal?

Answer 1

Ans. As in every experiment related to the photosynthesis, Co2 estimation, chlorophyll etc. the plant is kept in dark for a fixed time period. This is done because the plant has to be Destarched. The process of destarching helps in elimination of starch present on the leaf so that in order to observe and record the precise value of starch formed by photosynthesis could be done properly. Thus after destarching the plant also the plant function poperly carrying out photosynthesis i.e both the light and dark reaction normally.
