Why does the grass stretch during photosynthesis?
Because photosynthesis causes the molecules in the grass to take in carbon dioxide and water, and using light energy, created oxygen and glucose new molecules. The grass is indeed not stretching, it is becoming longer and larger due to more molecules. Explanation:
Is a seed a physical change or chemical change?
It’s a seed before it grows, and chemical reactions within its cells have to take place for that to happen. A good rule of thumb is to remember that physical changes can be reversed, like melting an ice cube or cooling gases. However, a chemical change cannot, like boiling an egg or burning paper. It’s chemical.
