化学与生物等学科联系紧密 ,学科间的交叉、渗透和综合 ,主要集中在植物的光合作用、动植物的呼吸作用、二氧化碳和氧气的性质等方面知识 .以此命题 ,成为考查学生综合应用能力和创新思维能力的又一亮点 .解题时 ,不仅要求学生有驾驭化学知识与技能的本领 ,还需具备联系、迁移? The disciplines such as chemistry and biology are closely related. The intercrossing, infiltration, and integration of disciplines mainly focus on the photosynthesis of plants, the respiration of plants and animals, the nature of carbon dioxide and oxygen, etc. As a proposition, it becomes a test for students’ comprehensive application ability. Another bright spot for innovative thinking skills. When solving problems, not only do students have the skills to master chemistry knowledge and skills, but also need to have contact and migration?
