Презентация, доклад по английскому языку на тему Фотосинтез.

Photosynthesis - is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities. This chemical energy is stored in carbohydrates molecules, such as sugars, which

Слайд 2Photosynthesis - is a process used by plants and other organisms to

convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities. This chemical energy is stored in carbohydrates molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek , phōs, "light", and ,synthesis, "putting together".
