Crystal morphology is an important characteristic of any crystal, which depends on many internaland external factors. Some of them are size, shape, and orientation of the seed. The aim of this paper is to analyzethe influence of the seed on the evolution of individual faces and, consequently, on the crystal morphology in agiven growth time. The results show that seed faces, even if they disappear in the first stage of growth, influencethe evolution of the directly neighboring faces. In particular, some of the seed faces, depending on the value of theinterfacial angle, cause a very intense increase in the size of the neighboring faces. Some other seed faces, for otherinterfacial angles, cause a decrease of the size of the directly neighboring faces. Such changes in the rate of increaseof various faces influence the evolution of these faces and modify the time-dependent crystal morphology.
