大家都知道,細胞是生物的基本結构单位,而原生质是其中有生命活动的部分。高等植物体和其他高等生物一样,是由一个受精的卵細胞衍生出来各种各样的細胞而构成。所以高等植物的生命活动,不論怎样复杂,最后都可归因于构成細胞內原生质的种种变化(細胞論)。另一方面,高等植物的許多細胞都不是各 As we all know, cells are the basic unit of biology, and protoplasm is part of which there is life activity. Higher plants, like other higher organisms, are made up of a variety of cells derived from a fertilized egg cell. Therefore, the life activities of higher plants, no matter how complicated, can eventually be attributed to the changes that make up the intracellular protoplasts (cell theory). On the other hand, many cells of higher plants are not unique
