不论人体有多少奥秘,都是组成人体的亿万个细胞活动的结果。人类对于自身的了解,直到300多年前荷兰人列文·虎克发明了第一台光学显微镜后,才开始深入到了细胞水平。随着观察与研究的不断深入,在19世纪中叶,两位德国科学家施莱登和施旺终于发现并且提出了具有划时代意义的细胞学说,认为动植物体都是由细胞构成的。 No matter how many secrets the human body has, it is the result of hundreds of millions of cells forming the human body. Human understanding of ourselves, until more than 300 years ago, the Dutch Levin Hooke invented the first optical microscope, it began to go deep into the cell level. With the continuous deepening of observation and research, in the mid-19th century, two German scientists Schleiden and Schwim finally discovered and proposed epoch-making cytology that animals and plants are made up of cells.
