单核花粉时期，细胞质中含有粗糙内质网、线粒体、质体等；小泡时期、细胞质中含丰富的粗糙内质网，且小泡聚合成大液泡，有丝分裂前的小泡子外壁已发育，内壁开始沉积。小孢子第１次有丝分裂完成后、在营养核与生殖核之间有１弧形细胞壁。初期的生殖细胞和营养细胞的细胞质中、细胞器是没有差别的，当生殖细胞发育至游离的裸细胞时，生殖细胞中质体不发育或退化，相反，营养细胞中的质体和线粒体在数量和大小上增加、在质体中积累淀粉。精细胞由椭圆形最后变为具尾延长的细胞，细胞质集中到尾部。绒毡层为腺质。单核花粉初期，绒毡层细胞质中富含粗糙内质网、质体、小泡、线粒体及高尔基体；最后，绒毡层细胞开始退化、绒毡层解体后，退化的细胞质流入花药腔中、内含乌氏体、脂滴等。
During the period of mononuclear pollen, the cytoplasm contained rough endoplasmic reticulum, mitochondria, plastids and so on. In the period of vesicle, the cytoplasm was rich in rough endoplasmic reticulum and the vesicles aggregated into large vacuoles. The outer wall of the vesicles before mitosis developed, The inner wall begins to deposit. After the first microschematic mitosis is completed, there is an arcuate cell wall between the vegetative and reproductive nuclei. In the early germ cells and vegetative cells, the organelles are indifferent. When the germ cells develop to free nude cells, the plastids do not develop or degenerate in the germ cells. On the contrary, the number of plastids and mitochondria in the vegetative cells Increase in size and accumulate starch in plastids. Sperm cells from the oval eventually become a tail extension of the cells, the cytoplasm concentrated to the tail. Tape tissue is glandular. In the early stage of mononuclear pollen, the tapetum was rich in rough endoplasmic reticulum, plastids, vesicles, mitochondria and Golgi; finally, the tapetum cells began to degenerate. After the tapetum was disintegrated, the degenerated cytoplasm flowed into the anther cavities , Containing Ubustum, lipid droplets and so on.
