Chloroplast absorbance
WebChlorophyll resides inside the chloroplasts and absorbs the light needed to convert water and carbon dioxide to oxygen and carbohydrates. There are two types of chlorophyll, a and b, but chlorophyll a is the main chlorophyll molecule used in photosynthesis. WebWhat color do chloroplasts absorb? The pigments of chloroplasts absorb blue and red light most effectively, and transmit or reflect green light, which is why leaves appear green. Photosynthesis does not only occur in the higher green plants; it occurs in algae and bacteria as well, albeit a little differently.

WebThe absorption spectrum of chloroplast pigments provide clues to the relative effectiveness of different wavelengths for driving photosynthesis. The action spectrum shows that the chlorophylls in the absorption spectrum are most important because they correlate closest to the action spectrum. WebJul 4, 2024 · Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not green. Because green is reflected or transmitted, chlorophyll appears green. Carotenoids absorb in the short-wavelength blue region, and reflect the longer yellow, red, and orange wavelengths.
