Question

Write two chemical changes which take place in plants?

Answer 1

Photosynthesis is the process through which plants convert light energy into chemical energy. Here is the chemical reaction involved:

`12 H_2O + 6 CO_2 + Light -> C_6H_(12)O_6 + 6O_2 + 6H_2O`

As we can see, water and carbon dioxide combine to form glucose and oxygen. Since new chemical species are formed, photosynthesis is clearly a chemical change.

Hope this helps.

Answer 2

There are many chemical reactions that take place throughout the life of a plant. Every moment of a plant's life, chemical reactions are regulating energy. Examples are Photosynthesis.
