42. A turgid plant cell is one that (A) lacks a cell wall. (B) has an extra cell wall layer. (C) lacks cytosol. (D) has excess water in its cytosol.

51. You are observing the embryonic development of a new species in your laboratory. This species has indeterminate development. You note a mutation in which one of the blastomeres (early cells) mutates and loses its function. What do you hypothesize would happen to this being? (A) Nothing—the remaining blastomeres would accommodate the formation of the necessary structures of the embryo. (B) Immediate embryo death—the remaining blastomeres could not accommodate the formation of the necessary structures of the embryo. (C) Uncertain future for the embryo—depending on which blastomere was lost, the remaining blastomeres might accommodate the formation of the necessary structures of the embryo. (D) The embryo would certainly lack some features as a result of the lost blastomere.
