When asked to set up an experiment to show that 'light is necessary for photosynthesis', a student ran to the school garden and set up the experiment by using a plant growing in the school garden.The experiment failed.His classmates made the following suggestions to get success in the experiment:Student A : Safranin should be used instead of iodineStudent B : The leaf should not be boiled in alcohol to remove chlorophyll before testing for starchStudent C : Transparent paper should be used instead of black paper stripStudent D : The leaf should be destarched before starting the experiment. The correct suggestion is given by:
student A
student B
student C
student D
In order to destarch the leaves for an experiment to show that sunlight is necessary for photosynthesis, the :
leaves are kept in alcohol and boiled in a water bath
leaves are soaked in iodine for two hours
plants with the leaves is kept in dark room for 48 hours
plant with the leaves is exposed to light of a lamp, a night before the experiment
An example of Dichogamy pollination is
Primrose
Palm
Banyan
