Dear student

â€‹â€‹â€‹â€‹â€‹1
Photosynthesis is the process through which plants convert light
energy into chemical energy Here is the chemical reaction involved:
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

2 Growth of a plant is not just a physical change but both physical
as well as a chemical change Physical because it involves changes
in the shape and size of the tree (tree on growing becomes bigger
in size and its branches spread out) Chemical because growth of a
plant is a biochemical process which is regulated by plant hormones
and enzymes

3 Respiration is a chemical change because it is taking in oxygen
and utilizing it to release energy as energy is released so it is a
chemical change
