A portion of each of four destarched leaves of a plant was covered with paper strips of various kinds. The plant was exposed to sunlight for 5 hours. Thereafter, the strips were removed and the leaves tested for starch in the covered portion. Which one of the four leaves gave the starch test in the covered portion?

In a experiment on two leaves - a variegated leaf or a leaf that was partially covered with black paper, and one that was exposed to light. Testing these leaves for what so that it becomes clear that photosynthesis occurred only in the green parts of the leaves in the presence of light.

A leaf of destarched healthy potted plant was covered by black paper strip as shown in Figure I, and kept in sunlight in the morning. In the evening, it was plucked off and tested for the presence of starch by using iodine solution. The observation is matched with the Figure No.:

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. The equation given below represents photosynthesis. Identify P and Q. P + "water" overset("sunlight")underset("chlorophyll")rarr "glucose + Q"

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 _________.

Therefore, it was necessary to obtain starch free leaves in the plant before starting the experiment. During the morning hours, using a fine blade, an incision was made to the leaves such that the phloem tissue was cut open. Analysis of the liquid oozing out was found to contain high amount of:
