On completion of the experiment to demonstrate that 'Light is necessary for photosynthesis', four students reported the inference as follows. Identify the correct inference:

Demonstrate with experiment that light is essential for photosynthesis

Name the following : Screen used to prove that light is necessary for photosynthesis

For the experiment 'Light is necessary for photosynthesis', the potted plant was first kept in darkness for a day. This is to:

The steps taken for setting up an experiment to demonstrate that 'light is necessary for photosynthesis', were as follows: * A strip of black paper was clipped on the leaf of a potted plant * The plant was kept in the sun for four hours * The strip was removed and the leaf was placed in boiling alcohol in a water bath * The leaf was washed and tested for starch The result was not as expected. Identify the step which had been missed out:

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 iodine Student B: The leaf should not be boiled in alcohol to remove chlorophyll before testing for starch Student C: Transparent paper should be used instead of black paper strip Student D: The leaf should be destarched before before starting the experiment The correct suggestion is given by:

In the experiment to show that light is necessary for photosynthesis, some of the steps of the experiment deal with the following activites: I. Starch reacts with iodine and gives blue-black colour II. Chlorophyll is dissolved in ethanol III.Hot water makes leaf tissue soft ltbgt The correct sequence of these steps is:

Why a leaf must be destarched before starting the experiment showing that light is necessary for photosynthesis ?

A star-shaped figure was cut in the black paper strip used for covering the leaf of a destarched plant used for demonstrating that light is necessary for photosynthesis. As the end of the experiment when the leaf was tested for starch with iodine, the star-shaped figure on the leaf was found to be:

In the experiment to show that light is necessary for photosynthesis, the pluked leaf is boiled in ethanol and then washed with water. After this, it is tested for the presence of a carbohydrate by a chemical which is:
