What is the purpose of photosynthesis in plants

Explanation;

Plants need energy all the time, they need it to grow, reproduce and do just about anything. This is where photosynthesis comes in, plants do photosynthesis because in the process it develops ATP which can be used as energy and can be broken down into ADP for the release of energy. So in short plants do photosynthesis for energy.

the answer is b)3/8x+1

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
