与“观察根尖的结构”这个实验直接相关的知识,位于义务教育生物课标第4个一级主题:生物圈中的绿色植物。其中涉及了2个二级主题,分别是“绿色开花植物的一生”和“绿色植物的生活需要水和无机盐”。在“绿色开花植物的一生”中,具体的内容要求为:“描述芽的发育和根的生长过程”。根的生长主要是通过根尖分生区细胞的分裂增多和伸长区细胞的生长伸长来实现的。在“绿色植物的生活需要水和无机盐”中,具体的内容要求为:“说明绿色开
Knowledge directly related to the experiment ”Observing the apical structure“ is located at Level 4 of the Compulsory Education Biology Curriculum: Green Plants in the Biosphere. There are two second-level topics involved, which are ”Life of a Green Flowering Plant“ and ”Life of a Green Plant Requires Water and Inorganic Salt“. In the ”life of green flowering plants “, the specific content requirements are: ”Describe the development of buds and root “. Root growth is mainly through the apical meristematic cell division increased and elongation of cell growth and elongation to achieve. In the ”green plants need water and salt“, the specific content requirements are: ”Description green on
