资源描述

1 -3.1 植物生长素的发现 2教学目标 分析植物体中生长素的产生和运输特点重点 分析植物体中生长素的产生和运输特点难点 分析植物体中生长素的产生和运输特点教学过程 时间 设计意图 个人备课一、 检查预习检查世纪金榜自主预习【28】完成情况。二、导入新课复习导入三、推进新课1.植物激素(1)概念:(1)产生部位:植物体内。(2)运输途径:从产生部位运送到_。(3)生理作用:影响植物_。(4)化学实质:微量_。(2)种类:2.生长素的产生、运输和分布3.植物的向性运动(总结)两看法判断植物“长不长、弯不弯”一看胚芽鞘尖端以下部分能否获得生长素。能,则生长;不能,则既不生长也不弯曲。二看胚芽鞘尖端以下部分生长素的分布是否均匀。若均匀,则直立生长;若不均匀,则弯曲生长。四、课堂训练 例:侧芽生长素的浓度总是高于顶芽,但是顶芽产生的生长素仍大量积存于侧芽部位,这是因为生长素运输的方式属于 ( )A.自由扩散 B.极性运输3130检查预习情况,为讲解新课铺垫。导入新课,口述学习目标讲授分析,掌握植物体中生长素的产生和运输特点- 2 -C.主动运输 D.渗透作用答案: C五、课堂小结六、 作业和预习1、完成课时作业本“课时作业九”2、预习生长素的生理作用641当堂训练,检测知识运用总结本课学习内容,学生记忆相关知识点。布置下节课的预习任务教学反思
