PARTS OF FRUITS
A fruit as a whole
is not a single solid product; it
is divided into certain parts among
itself. Generally the parts of the
fruits are divided into two fruit
layers. They are,
Pericarp
Exocarp, the outermost layer often
consisting of only the epidermis
Mesocarp, or middle layer, which varies
in thickness
Endocarp, which shows considerable
variation from one species to another
Seed
During the development
of the fruit, the wall
of the ovary, called per carp, usually
thickens and becomes differentiated
into three layers, which may or may
not be easy to distinguish visually.
These layers are called the Exocarp,
Mesocarp, and endocarp. As an example,
in the peach, the Exocarp is the skin,
the Mesocarp is the fleshy part, and
the endocarp is the stony pit. The
seed, containing the embryo, is inside
the pit.
.
Fruit matured ovary of the pistil
of a flower, also containing the seed.
After the egg nucleus, has been fertilized
(see fertilization) and the actual
embryo plantlet begins to form, the
surrounding ovule (see pistil) develops
into the seed and ovary wall (per
cap) around the ovule forms the fruit.
Per carp consists of three layers
of tissue; the thin outer Exocarp,
which becomes the “skin”
the thicker Mesocarp; and the inner
endocarp, immediately surrounding
the ovule. A flower may have one or
more simple pistils (each called a
carpel); different arrangements give
rise to different types of fruit.
A new variety of fruit is obtained
as a hybrid in plant breeding or may
develop spontaneously by mutations.

fruits with Tomato Fruit.
