Before testing the leaf for starch at the end of the experiment, 'light is necessary for photosynthesis', the experimental leaf should be boiled in:

Given alongside is a sketch of a leaf partially covered with black paper and which is to be used in the experiment to show that light is compulsory for the process of photosynthesis. At the end of the experiment, which one of the leaf parts labelled I, II and III will become blue black when dipped in iodine solution?

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:

Out of the following figures, choose the one showing the correct procedure for removing chlorophyll from the leaf in the experiment 'light is necessary for photosynthesis': The correct procedure is:

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:

A protion of destarched leaf of a potted plant was covered with a black strip of paper. The plant was then exposed to sunlight for six hours and then tested for starch. It was observed that:

The steps necessary for setting up the experiment, 'To demonstrate that light is necessary for photosynthesis' are not given here in proper sequence: I. Keep the potted plant in sunlight for 3 to 4 hours. II. Keep the potted plant in darkness for about 48 hours. III. Cover a leaf of the plant with a strip of black paper. IV. Pluck the leaf and test it for starch. The correct sequence of steps is:

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:

Some experiments were carried out using Croton sp. plants to understand the process of photosynthesis. It was observed that the leaves of the plant exposed to light for longer duration accumulated more starch. However, due to presence of pre-formed starch in the leaves, it was difficult to find the net productivity on a fixed exposure to light source. Therefore, it was necessary to obtain starch free leaves in the plant before starting the experiment. Some of the starch free leaves were coated with wax on both the surfaces. The plant was maintained under normal environmental conditions. At the end of the experiment, the wax coated leaves are likely to show _________.
