This is just an educated guess. As the purple pigment, caused by anthocyanins, are on the bottom side of the plant, their purpose could probably be to direct the light.
Specifically, a purple pigment on the bottom of the plant would absorb certain wavelengths near the purple spectrum, and reflect other wavelengths back toward the portion of the plant with chlorophyll. In this way, light does not simply pass through the leaf, instead it is reflected back in towards the chlorophyll to maximize the amount of light being used for photosynthesis.
Answer:.a. volume increases proportionally more than the surface area.
Explanation:
As a cell size becomes enlarge this results in increase in volume and the membrane of the cell also increases. But the volume increases more rapidly then the surface area of the cell. As a result of this the amount of surface area required so as to pass the materials with respect to the unit volume of the cell also decreases.
