In
botany a
capsule is a type of simple, dry
fruit produced by many species of
flowering plants. A capsule is a structure composed of two or more
carpels. In Angiosperms (flowering plants), the term
locule is used to refer to a chamber within the
fruit. Depending on the number of locules in the ovary, fruit can be classified as
uni-locular (unilocular),
bi-locular,
tri-locular or
multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the
ovules or
seeds.
