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.
