The biology class agenda covers reviewing organelles, defining key terms like vacuole and cell wall, and comparing plant and animal cells. The teacher will define organelles found in both like vacuoles and only in plants like chloroplasts and cell walls. A warm-up questions students to define organelle and identify ER and Golgi differences. The review has students make cell part analogies. Plant cells are outlined as having cell walls, chloroplasts, and large vacuoles while animal cells contain centrioles.
