高中生物教材中有关酵母菌的知识分布于很多章节,涉及细胞呼吸、种群数量的动态变化、果酒制作、酵母细胞固定化等主干知识,也成了近几年高考考查的热点。以下是笔者整理的酵母菌的相关考点:一、酵母菌的分布酵母菌在水果、蔬菜表面以及土壤里均有分布;在牛奶、动物的排泄物及空气中也有分布。尤其喜欢在偏酸性、温暖潮湿且含糖较多的环境中生长,大多数营腐生生活。二、酵母菌的形态结构酵母菌是单细胞真核生物,通常为圆形、卵圆形或椭 Knowledge of high school biology textbooks on the distribution of yeast in many chapters, involving the cell respiration, the dynamic changes in the number of populations, fruit wine production, yeast cell immobilization and other key knowledge, has become a hot spot in recent years college entrance examination. The following is the author of the yeast sorting test sites: First, the distribution of yeast Yeast in fruits, vegetables and soil surfaces are distributed; in milk, animal waste and air also have distribution. Especially like to grow in acidic, warm, humid and sugar-rich environment, most of the camp saprophytic life. Second, the morphological structure of yeast Yeast is a single cell eukaryotes, usually round, oval or oval
