Read p. 467 + on the seed bearing plants. Answer the overhead questions and be prepared to either hand in, if requested, or to have a quiz on the material that they cover.
Also, study for the animals test, which is next block (8 May 2013), and which includes echinoderms, arthropods, chordates, and general knowledge about animals. Use the textbook, notes, and other materials (diagrams, crosswords, etc) to help with your studying.
