What Are Analogies for Chloroplasts?
According to Online Digital Education Connection, analogies for chloroplasts are power plants that imitate the function of chloroplasts in a plant cell to utilize solar energy or light in the processing of food for plant cells. Score Science lists solar energy plants as city analogies for chloroplasts.
AaronSklar.com draws another analogy between chloroplasts in plant cells and windmills, saying the latter utilizes raw wind energy to produce energy for city use, just as the former converts light energy of the sun into food for plants.
Chloroplasts produce food for plants through photosynthesis. Through synthesis of proteins, chloroplasts utilize captured radiant energy from the sun, which is then stored in plant cells as chemical energy in the form of glucose. An analogy is drawn whereby chloroplast function is compared with the use of solar panels in sections of an airport. Again, the panels convert sun rays into electricity, a form of energy utilized in airports.
Chloroplasts are green in color. They contain the chlorophyll pigment, which absorbs red and blue colors and reflects them as green during the processing of food using light energy. It is the reflection during photosynthesis that makes chloroplasts look green. Components of chloroplasts include outer and inner membranes, stroma, granum and thylakoid.
