E. photosynthesis - synthesis reaction in which carbon dioxide and water, using radiant energy, form simple sugars, like glucose. Oxygen gas is released as a by-product. F. digestion - breakdown of food substances into simpler form by chemical & mechanical means.

q. photosynthesis - chemical. r. sublimation - physical. Part (m) of this question can be understood two ways: does 'exposion' means the actual opening up of the container (a bomb, for example) or does it refer to the chemical inside the bomb reacting? The exposion which throws pieces of the bomb about is a physical change, the chemical ...

CHAPTER 8 – PHOTOSYNTHESIS
22. Photosynthesis is a chemical reaction. 23. Adding energy, adding a solute, and tearing matter are ways to cause a physical change to occur. 24. Dissolving is a physical change. 25. Water is boiling in a pot and bubbles are rising to the top of the water. The gas production indicates a chemical change. 26. Color change, temperature change ...

The overall chemical change during photosynthesis is the reverse of cellular respiration. In its simplest possible form: CO2 + H2O + light energy ([CH2O] + O2 [CH2O] represents the general formula for a sugar. One of the first clues to the mechanism of photosynthesis came from the discovery that the O2 given off by plants comes from H2O, not CO2.
Is photosynthesis a chemical change or physical change ...
Form hypothesis: During photosynthesis, light energy is used to synthesize carbon dioxide (CO. 2) and water (H 2 O) into glucose (C 6 H 12 O 6) and oxygen (O 2).The complex series of chemical reactions is summarized by the following formula:
