Heya mate!! Here is the solution of your question :-

Photosynthesis is necessary in plant due to the following reasons :-

1. Plants prepare food for themselves during the process of photosynthesis , thus if it will not happen plants will not be able to prepare their food
2. The food prepared during the process of photosynthesis is used by plants for their growth and maintenance as well as these food is also used by other animals .
3. It helps in controlling the rate of green house gases such as Carbon dioxide , during this process a large amount of oxygen is evolved , and harmful gases are absorbed during this process . Thus , helping others i.e. animals and other organisms to get fresh air and food
