Answer: simple inorganic molecules to sugar
Explanation:
Through the process of photosynthesis plants use the green coloured pigment named chlorophyll present in their leaves to trap sun light (solar energy) alongside other simple inorganic molecules like atmospheric carbon dioxide and water to produce sugar molecules (usually glucose) which is later stored as starch.
The controlled experiments are performed by the scientists, when they want to study the changes in the sample on changing a single variable. So, the correct answer is option (b).
In case, all variables are kept same, no changes would be observed in the experiment sample. A controlled experiment can be performed on living thing as well as non living. But, controlled experiment cannot be performed on the things which are influenced by a lot of variables, as they cannot create realistic results. So, the option (a), (c), and (d) are incorrect.
The awnser is true!! I hope this helped!
