Are the following statement true or false? Give a reason in support of your answer.
If you immerse a leaf intact on the plant in ice cold water, it will continue to photosynthesise in bright sunshine.
"Oxygen is a waste product of photosynthesis." Comment.
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.
