A potted plant was taken in order to prove a factor necessary for photosynthesis. The potted plant was kept in the dark for 24 hours. One of the leaves was covered with black paper in the centre. The potted plant was then placed in sunlight for a few hours.
(i) What aspect of photosynthesis was being tested?
(ii) Why was the plant placed in the dark before beginning the experiment?
(iii) During the starch test, why was the leaf
(1) boiled in water
(2) boiled in methylated spirit
(iv) Write a balanced chemical equation to represent the process of photosynthesis.
(v) Draw a neat diagram of a chloroplast and label its parts.

The diagram given below represents an experiment to prove the importance of a factor in photosynthesis. Answer the questions that follow :
What will you observe in the experimental leaf after the starch test?
Complete the following by filling in the blanks numbered 1 to 10 with the appropriate word/term:
Photosynthesis involves light reaction and dark reaction. During light reaction, the chlorophyll present in the (1) ______ gets activated by absorbing light energy. This energy splits (2) ______ molecules to (3) ______ and oxygen and releases two electrons. This process is called (4) ______. The (5) ______ ions are picked up by NADP to form (6) ______. The ADP is converted to (7) ______. This process is called (8) ______. During the dark phase, the compound produced at the end of the light reaction reacts with carbon dioxide to form (9) ______. This product is converted to starch. The process is called (10) ______.
Which one chemical reaction occurs during photosynthesis?
Are the following statement true or false? Give a reason in support of your answer.
Photosynthesis is considered as a process supporting all life on earth.
A candidate studied the importance of certain factors in photosynthesis. He took a potted plant and kept in the dark for over 24 hours. In the early hours of the next morning, he covered one of the leaves with black paper in the centre only. Then he placed the plant in sunlight for a few hours and tested the leaf which was covered with black paper for starch.
Is there any control in this experiment? If so, state it.
Photosynthesis in green plants is directly and indirectly dependent on so many plant structures.
Explain briefly the role of the following structures in this process is Stomata.

Mention, if the following statement is True or False. If false rewrite the wrong statement in its correct form:
Photosynthesis can also occur n artificial light such as that of a 100-watt electric lamp.
Choose the Odd One Out
State whether true or false. If false, correct the statement.
When the weather is hot, water evaporates lesser which is due to opening of stomata.
