苏科版生物教材中,关于植物体的组成,并没有说出根与茎的区别。在教学中,学生往往对生长在地面以下的根和茎难以区分。学生容易将一些变态的地下茎误认为是根。因此在课堂教学中,教师应该对变态的根和茎的区别做一些准备,以便更好地帮助学生建构根和茎的相关科学概念。现以大家常见的植物帮助大家予以区分。 Su Ke version of biological textbooks, on the composition of plants, did not say the difference between roots and stems. In teaching, students are often indistinguishable from roots and stems that grow below the ground. Students easily mistaken for some perverted underground stems is the root. Therefore, in classroom teaching, teachers should make some preparations for the difference between perverted roots and stems in order to better help students to construct related scientific concepts of roots and stems. We are now common to help everyone to distinguish between plants.
