A. | Haemoglobin |
B. | Chromatophore |
C. | Chlorophyll |
D. | Pneumatophore |
Answer» B. Chromatophore | |
Explanation: Chameleons have specialized cells, chromatophores, which contain pigments in their cytoplasm, in three layers below their transparent outer skin. Dispersion of the pigment granules in the chrornatophores sets the intensity of each color. When the pigment is equally distributed in a chromatophore, the whole cell is intensively colored. When the pigment is located only in the centre of the cell, the cell appears mainly transparent. |
