Answer:

Changes that take place in presence of sunlight are

a) Photosynthesis- The process by which green plant prepare their own food in presence of sunlight and green pigment Chlorophyll present in leaves

b) Ozone Formation-UV radiation from the sun split molecular oxygen into atomic oxygen.

c) Vitamin D-Vitamin D in the skin exposed in presence of sunlight.

d) Activation Of Melanin pigment-Melanin pigment protect skin from UV radiation.When sun level rises our dermis darkens to give us desirable suntan.

e)Solar Cells-Electrical device that convert sunlight energy into electricity by photovoltaic cells.

Answer:

The reaction which takes place in the presence of sunlight is the reaction which is used by plants and other organisms to convert light energy into electrical energy. In this reaction light energy is captured and it is used to convert water and carbon dioxide into oxygen and other organic compounds which are rich in energy.

Explanation:

Complete step by step answer:

In the presence of sunlight green plants prepare their food by taking in CO2 and H2Ofrom air and soil respectively with the help of chloroplasts present in the green leaves of plants. This reaction is known as photosynthesis.

The reaction involved is mentioned below:

6CO2+6H2O−→−−−−−chlorophyllsunlightC6H6O12+6O2

Photosynthesis is performed differently by different species but some of the part is common, the carbon dioxide enters in the leaf of the plant through stomata by the process of diffusion. Photosynthesis occurs in the chloroplast. Leaves contain a green pigment known as chlorophyll, it absorbs the light energy from the sun. Oxygen is the waste product produced in the process of photosynthesis.
