synthesize sugars.
transform proteins into useful nutrients.
transform sugar into cellular energy.
synthesize proteins.
Chloroplasts absorb light energy which is used to synthesize sugars, a crucial function of chloroplasts, hence option A is correct.
What is the function of the chloroplast?
They transform solar energy into glucose and give the cell structure. They surround the cell and keep it apart from other elements of its surroundings.
In some organisms, the process of photosynthesis involves the use of chloroplasts. The sun's energy is absorbed by the chloroplast, which uses it to create sugars.
As a result, active substances such as amino acids, phytohormones, nucleotides, vitamins, lipids, and secondary metabolites are produced by chloroplasts.
Therefore, using glucose as fuel, they produce useful energy, the sun's energy is absorbed by the chloroplast, which uses it to create sugars.

Damage caused by UV light leading to thymine dimers is corrected during photorepair by the enzyme ______. Multiple choice question.
Answer:
photorepair
Explanation:
Damage caused by UV light leading to thymine dimers is corrected during photorepair by the enzyme photoreactivation called as PRE. Thymine dimers are a problem leading to skin cancer in future.
What happens when the thymine dimer are not repaired ?If the thymine dimers are not repaired then it will lead to a condition of mispairing in DNA , transcription blocking.
It will lead to a condition of multiple growth of cells called as tumor where if uncontrolled UV exposure condition takes place then it will lead to skin cancer and is not curable if deadly stages comes up.
PRE enzyme in the presence of blue light breaks up the dimers and again restores the condition.
Therefore, DNA photolyase is the enzyme which stores energy and breaks the covalent bonds between the thymine dimer and restores the structures.
