Base your answers for questions 55 and 56 on the information below and on your knowledge of biology.

growth of corn seedlings toward light. In the experiment, equal numbers of albino
(lacking chlorophyll) corn seedlings and green corn seedlings were grown at a
temperature of 24C. All other environmental conditions were the same for both
groups of seedlings. The results of the experiment showed that both the albino
seedlings and the green seedlings bent toward light.
