A plant has a unique photosynthetic pigment, causing the leaves of it to appear reddish-yellow. What wavelengths of visible light are being absorbed by this pigment

blue-violet

Explanation:

Generally the appearance of a photosynthetic plants depends on the wave of light on the absorption spectrum that the pigments absorbs.  Thus a leaf appears green at  sight  because the  chlorophyll pigment  absorbed  wavelength of lights in red-blue-violet region, and reflect green back to the eyes.

Carotenoids appears as orange-yellow in color to eyes.Thus the plant in the question is a carotenoids. They usually absorbed light in blue-violet region of absorption spectrum. Therefore since this plant  is a carotenoids, definitely it must absorbed in Blue-violet ,(400-550mn) and appear orange-yellow since it did not absorbed this but reflects  back to eyes.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
