An experiment was set up as shown in the diagram. What is the aim of the experiment?

This experiment is set up for the process of photosynthesis. The aim of this experiment is to check the process of photosynthesis. Starch is formed in this process.

An experiment was set up as shown in the diagram. Why was a part of the leaf-covered with black paper?

Black paper is used to cover the leaf as it blocks the entry of light to the leaf as it is a good absorber of light. During this experiment covered part of the leaf turns yellow after a week because chlorophyll is no longer. Hence, no photosynthesis occurs in the covered portion.

An experiment was set up as shown in the diagram. What test would you do on the leaf after a few hours?

I would do a starch iodine test on the experimental leaf after a few hours to check the effect of photosynthesis.

An experiment was set up as shown in the diagram. Explain the result obtained from the above experiment.

The result shows that the exposed portion turns blue-black showing the presence of starch, while the portion that covered with black paper turn yellowish-brown, there is no starch formed in it.

An experiment was set up as shown in the diagram. Why is it necessary to perform the test mentioned in (iii) above?

Starch- iodine test is necessary because when you put iodine on the leaves, an exposed portion will turn blue and the other will be brown. Iodine is an indicator that turns blue-black in the presence of starch.

Mitosis is a type of cell division that results in two daughter nuclei. Each contains a similar number of a chromosome as the parent nuclei. The main purpose of mitosis is for growth and to replace worn out cells.
