Answer:
The basic function of the light reactions of photosynthesis is the conversion of solar energy to chemical energy.
Explanation:
In photosynthesis, the light energy is captured by chlorophyll pigment which is present in the thylakoid membrane. Then this light energy is used split water which releases the electron that enters the electron transport chain. Then electrons move through several electron carriers and helps to generates NADPH and ATP.  
These NADPH and ATP are used in the Calvin cycle to fix the carbon into carbohydrates like glucose. Glucose molecules is then used by the plant to get energy source and to make structural components like cell wall. Therefore during photosynthesis solar energy is converted into chemical energy like glucose.
 
        
             
        
        
        
Answer:
Explanation:
An organism can't chose to have a mutation because it depends on the way they are born. If they are missing some type of mineral, (Protein, Vitamin, etc.) they will have a mutation because they're missing that. Well, something similar to a mutation is natural selection and genes. For example, there are some short and tall giraffes. The tall ones can reach the tree and the short ones can't so they die and the tall ones can reproduce and their offspring will inherit that trait
