Abstract:	The sweet sorghum (Sorghum bicolor (L.) Moench subsp. bicolor) caryopsis has a complex structure. The value of caryopsis consists not only in insuring the species reproduction, but has other usage, one of this is as malt. In the African countries, similar to rise, the sweet sorghum represents a source of starch, proteins, and is being used as food for people and animals. Sweet sorghum is also used to produce ethanol, currently utilize as biofuel in many countries. The embryo’s endosperm incorporates it’s nutritive reserves, and is providing the energy necessary for the plantlet to grow. Though the sweet sorghum endosperm was cytological and biochemical studied, one can observe that the study of embryos morphology and the dynamic produced at this level in the first 48 hours were neglected, as the aspects related to it’s fast growing characteristic. We suggested that such a plant material may serve as experimental model in many studies of plant physiology.
