First, the teaching objectives 1. Knowledge goals (1) to understand the relationship between cell surface area and volume, and the relationship between cell size and material access. (2) understanding the smaller the cell surface area, the more conducive to material exchange. (3) Overview The reason why cells can not grow indefinitely. 2. Ability to learn to use data tables, tables to analyze the problem. 3. Emotions, Attitudes and Values Objectives enable students to have critical thinking skills, realistic scientific attitude and meticulous scientific spirit. Second, the teaching focus by exploring the relationship between cell size and material transport simulation experiments to understand the cell is not
