Solution
Photosynthesis involves light reaction and dark reaction. During light reaction, the chlorophyll present in the leaves gets activated by absorbing light energy. This energy splits water molecules to hydrogen ion and oxygen and releases two electrons. This process is called photolysis. The hydrogen ions are picked up by NADP to form NADPH2. The ADP is converted to ATP. This process is called photophosphorylation. During the dark phase, the compound produced at the end of the light reaction reacts with carbon dioxide to form glucose. This product is converted to starch. The process is called polymerization.

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.
Name the plant part
- Which bends in the direction of gravity but away from the light.
- Which bends towards light but away from the force of gravity.
Study the pictures below and then complete the table by putting a plus (+) if the shoot or root grows towards the stimulus and a minus (-) if it grows away from it.
| Stimulus | Light | Gravity |
| Shoot | + | - |
