Answer:
we use a plastic cover ot a jar to cover becoz we need to prevent the income of air as it will disturb the experiment
As KOH breaks down, the oxygen needed for cellular respiration is released. It serves as a temporary energy source for the respiring organism. It binds with carbon dioxide to form a solid, preventing CO2 production from affecting
Potassium Hydroxide is an inorganic solid compound which absorbs Carbon Dioxide gas. This means Potassium Hydroxide is something that can help us to do our experiment.gas volume.
Explanation:
No, both the leaves do not show the presence of the same amount of starch, because in photosynthesis starch is produced using sun light, chlorophyll and CO2. In first set up availability of CO2 will be less for making starch by the plant leaves, as potassium hydroxide (KOH ) absorb the CO2. In second plant setup, the leaves will have more amount of starch.
