Root cells of beetroot plants contain a red pigment. If small pieces of root tissue are placed in cold water, part of the red pigment escapes from the cells into the water. An experiment was done to examine how temperature affects the amount of red pigment lost from the root cells. The results showed that, as the temperature of the water increased, the rate at which red pigment was lost from the root cells also increased. Which statements could account for this pattern?
- A1 and 2
- B2 and 3
- C2 only
