This paper describes an alternative trial to simulate evolutionary and developmental process of multi-cellular plants in 3D Euclidean space. Starting from a seed on the surface of the ground, each individual grows by spawning daughter cells of each active cells. The rule set of growth is encoded as a gene on the chromosome that indicates the orientation of daughter cell and state transition. The model is very simple but includes a type of metabolism for absorbing water at the root underground and photosynthesis at the cells above the ground. Through the computer simulation of evolutionary process by a genetic algorithm with a fitness measure given by the number of cells, a variety of phenotypic shapes which are similar to moss have emerged.
