Solution:
The correct option is (1).
In 1854, Julius Von Sachs proved that glucose is produced during the process of photosynthesis in the green parts of the plant. He also found that starch is the storage form of glucose in plants. Furthermore, he showed that chloroplast is the cell organelle that houses the green pigment chlorophyll in plants.
He observed that if a leaf containg starch is kept in darkness for a while, the starch disappears and if the same leaf is exposed to sunlight, the starch reappears in chloroplasts.
