Question

section 4.2 overview of photosynthesis key concept the overall process of photosynthesis produces sugars that store chemical energy. photosynthetic organisms are producers. some organisms are called producers because they produce their own sources of chemical energy. other organisms also use the chemical energy that producers make. plants are producers. plants capture energy from sunlight, and store it as chemical energy in the form of sugars. these sugars are made through photosynthesis. remember from section 3.2 that chloroplasts are organelles in plant cells where photosynthesis takes place. chlorophyll (klawr - uh - fihl) is a molecule in chloroplasts that absorbs some of the energy in visible* light. plants use energy in visible light for photosynthesis. visible light looks white, but it is made up of different wavelengths, or colors, of light. plants have two kinds of chlorophyll, called chlorophyll a and chlorophyll b. these two types of chlorophyll absorb red and blue wavelengths of light. neither type of chlorophyll absorbs much green light. plants are green because green wavelengths of light are reflected by chlorophyll. what is the role of chlorophyll in photosynthesis?

Explanation:

From the text, chlorophyll is a molecule in chloroplasts. It absorbs some energy in visible light (specifically red and blue wavelengths, and reflects green). This absorbed light energy is used by plants for photosynthesis to make sugars (store chemical energy). So its role is to absorb light energy (from visible light, specifically red and blue) for photosynthesis.

Answer:

Chlorophyll is a molecule in chloroplasts of plant cells that absorbs energy in visible light (specifically red and blue wavelengths, while reflecting green light). This absorbed light energy is used by plants to carry out photosynthesis, through which plants capture energy from sunlight and store it as chemical energy in the form of sugars.
