CHAPTER 2 : CHALLENGE AND EXTENSION

KEY CONCEPT: Plants are Producers.

During photosynthesis, plants capture energy from sunlight and convert it to chemical energy in the form of sugars. Plants often store sugars as starches. When the plant needs energy, the starches are broken back down into sugars and energy is released. Many plant stems or roots are adaptations for storing sugar or starch.

Answer the Following: A potato will eventually form sprouts that can become new plants. What is the energy source for the sprouts?
