RE:I'm not competely sure, but I think its sunlight. It is because: carbon dioxide + water (+light energy) ---> glucose + oxygen
The energy photosynthesis comes from the sun's light energy.
Plants use sunlight as the primary source of energy to carry out photosynthesis. The sunlight is absorbed by pigments in the chloroplasts of plant cells, where the light energy is converted into chemical energy in the form of glucose.
The energy for photosynthesis comes from respiration. The plant takes in oxygen and uses it for energy with in its cells. The chloroplast have a green substance called chlorophyll which absorbes the light needed for photosynthesis. the reaction happens there. Unfortunately the previous answer is not quite right. The ultimate source of energy for photosynthesis is sunlight. Plants convert the light energy into chemical energy in the form of glucose, which they can then use as a source of energy in their cells. Energy is released from glucose by respiration.
photosynthesis.
The energy captured in glucose ultimately comes from the sun. During photosynthesis, plants absorb sunlight and convert it into chemical energy stored in glucose molecules. Organisms then utilize this stored energy in glucose through cellular respiration to fuel their life processes.
the sun, photosynthesis
It comes from sunlight
Photosynthesis is the capturing of the light's energy and converting it into chemical potential energy, so it comes from the sun.
The energy for photosynthesis comes from the sun.
sunlight.
It comes from the sun.
the sun the sun
From the sun - sunlight
The energy photosynthesis comes from the sun's light energy.
it comes from sunlight
It comes from light. Light energy is absorbed
The energy comes from the plants because photosynthesis is being taken place
