The photosynthesis of plants can be expressed as water + carbon dioxide - glucose + oxygen, so it can be judged that starch must contain carbon dioxide_______ Elements, which may contain______ element
The answer is that there must be hydrocarbons, possibly oxygen
Why?

According to the law of conservation of mass, the kinds of elements are invariable
Water and carbon dioxide contain carbon, hydrogen and oxygen, while oxygen contains only oxygen. Therefore, it must contain hydrocarbon and may contain oxygen

Does plant photosynthesis convert oxygen into carbon dioxide

On the contrary, it is to convert carbon dioxide into oxygen, that is, to absorb carbon dioxide and produce oxygen

In order to explore the effect of light on photosynthesis, green plants absorb carbon dioxide and exhale oxygen under sunlight
The students collected the air from the vegetable greenhouse in the sunny day and the early morning when the sun did not rise, and compared the carbon dioxide content. How to test the sampled gas? What conclusions can be drawn?
What conclusions can be drawn

Add clear lime water with rubber head dropper and observe the turbidity by shaking!
