Which characteristic property allows multicellular algae, like red, green, and brown algae, to make the maximum use of sunlight? The presence of accessory photosynthetic organs other than the chloroplasts helps algae in absorption of the maximum amount of sunlight. The presence of Chlorophyll a, b, and c and various accessory pigments help absorb light at various wavelengths. The flattened body surface of the algae increases the area of absorption for sunlight, which allows algae to make the maximum use of sunlight.
