  <b>Abstract</b>
Strings are sequences of symbols from a finite alphabet. A
grammar is a set of rules for string rewriting. The well-known Chomsky
hierarchy consists of different types of grammars (regular, context-free,
context-sensitive and type-0) obtained by imposing specific restrictions
on the format of the rewrite rules. Formal Language Theory has obtained
deep results about grammars. Grammars have been widely used in areas such
as compilers, program verification, linguistics, natural language
processing and bioinformatics. In Chomskian grammars, only one symbol is
rewritten (using one rule) in one step of string rewriting. L-systems are
a generalization where all symbols in the string are rewritten in one
step. We begin with a brief overview of Chomskian grammars. We then
introduce various types of L-systems and their applications to modeling
various aspects of plant growth.
