A tree growing is a chemical change because the chemical reaction that happens in the trees cells causes the carbon dioxide and water to become sugar (food) for the plant to grow and oxygen it can "exhale" much like we exhale carbon dioxide.
A flower growing in a garden is a chemical change because of all the different chemical reactions going on like absorption, photosynthesis, growth, etc. Its growth also cannot be reversed.
Growing a flower involves both physical and chemical changes.
It is a physical change its still grass its just growing

The browning of a flower is a chemical change. Color changes are one sign of a chemical reaction.
Chemical
Strictly speaking, the initial volatilizing (evaporation) of the perfume is a physical change but, soon after contact with oxygen, the volatile organic compounds and other components of the perfume begin oxidizing. In that case, there is a chemical change.
yes because it does not change chemical composition anddoes not form new substance.

if you want the answer in scientific terms it is classified a chemical change
Chemical due to the internal reactions of a flower.
entirely chemical
The flower buds changing into a flower
the blooming of a flower is known as a physical change because when it blooms there is no new substance formed so the blooming of the flower is a physical change but it is irreversible
Chemical property. Unless the smell is changing, in which case it's a chemical change.
Yes like when it dies or when it is growing.
phisical, unless using bleach. bleach actually changes pigment, while normal dye just covers-up the existing color.
