Answer 2

Answer:

The growth of plants is a chemical change.

Explanation:

A chemical change is a type of change in which new substances are formed. The plant grows to form branches, seeds, flowers, fruits, and buds. They grow by increasing their thickness, length of the branches, growth of roots, etc. Certain facts claiming that plant growth is a chemical change are described below:

• Plants develop from seeds and as they grow, they cannot be reverted back to seed.

• Plants prepare food utilizing solar energy and carbon dioxide gas to prepare glucose as a new substance by the process of photosynthesis helping plants to grow.
• In addition, plants also produce growth hormones such as auxins and cytokinins which promotes their growth.

Therefore, these facts prove that the growth of plants is an example of chemical change.
