During photosynthesis, light energy is converted into chemical energy. The energy is stored in carbohydrate molecules including glucose and starch. More »

Respiration, in which energy is released from carbohydrates for metabolic needs, takes place in plants through a process which can be expressed in a word equation as: glucose + oxygen = energy + carbon dioxide + water. T... More »

Respiration in living organisms works by exchanging gases to support essential metabolic processes. Most animals inhale oxygen and exhale carbon dioxide, whereas plants consume carbon dioxide and expel oxygen. Gas exchan... More »

Food for a plant is made in its leaves through photosynthesis, a process in which light energy is converted into chemical energy. The product of photosynthesis is a sugar called glucose, which is then used to fuel the pl... More »

The energy required for photosynthesis comes from the sun as light energy; plants transform this light energy into chemical energy, or sugars. Plants perform this energy conversion using light, water, carbon dioxide and ... More »

Autotrophic dinoflagellates create their own food by converting light energy into chemical energy using photosynthesis. Heterotrophic dinoflagellates receive nutrition from processing other complex organic substances. Th... More »

Plants require carbon dioxide, light energy and water to complete photosynthesis. Photosynthesis results in the production of oxygen, water and glucose. Plants use glucose to store energy. More »
