Answer:
1. Option C
2. Option D
3. Option B
4. Option D
Explanation:
Requirement 1
D is the Chloroplast, which is the site of photosynthesis, and E is Mitchondria, where energy conversation occurs means cellular respiration done here.
We all know that in the Chloroplast plant makes their food with the help of sunlight, carbon dioxide, and water. After making its food, it produces oxygen as a waste product, which is needed for all to live.
In Mitochondria, cellular respiration occurs. Mitochondria are known as the powerhouse of any cell. Here, the conversion of chemical energy from food occurs to create energy for the cell ( respiration process).
So, from the fig, we can able to say that the answer is option 3. D photosynthesis, E: Cellular respiration
Requirement 2
All eukaryotic cells have Mitchondria. Mitochondria are known as the powerhouse of any cell. Here, the conversion of chemical energy from food occurs to create energy for the cell. Mitochondria, using oxygen available within the cell, convert chemical energy from food in the cell to power in a form usable to the host cell.
Like the chloroplast, mitchondria is making food or energy for the cell. So, it can be said that unlike photosynthesis, cellular respiration occurs in all eukaryotic cells.
Requirement 3
There are two types of cellular respiration: aerobic, and another is anaerobic. At the time of aerobic cellular respiration, glucose reacts with oxygen. From this reaction, ATP is formed, which is directly used by the cell.
During the cellular respiration process, some living systems use an organic molecule as the final electron acceptor. Procedures that use an organic unit to regenerate NAD+ from NADH are collectively referred to as fermentation.
From this, we can clearly say that cellular respiration does not consume carbon dioxide.
Requirement 4
A calorimeter is an equipment that is designed to measure the energy released or absorbed during a chemical reaction or phase change. Food calorimetry allows us to determine the number of calories per gram of food. In this activity, a piece of food is heated, and the released energy is used to heat a known quantity of water. The temperature change (∆T) of the water is then used to determine the amount of energy which is present in the food.
The potential energy of any food can not be determined unless they are combusted in the calorimeter because when they burned in the calorimeter, they release energy. By this released energy, the potential energy of any food can be measured.
