6. Characteristics contin..
Single or Multiple Cotyledons
Traditionally, flowering plants are divided into two main
classes--monocots (Liliopsida) and dicots (Magnoliopsida--
depending on the number of cotyledons they contain.
The cotyledon is the part of the seedling first visible when it
grows out of the soil.
This leafy structure is wrapped around the seed and supplies
essential nutrients to it.

7. Characteristics contin..
Monocots feature an embryo with a single cotyledon
while dicot flowering plants feature two cotyledons.
It is for this reason monocots are called monocotyledonae
(single cotyledon) and dicots are called dicotyledonae
(two cotyledons).

8. Characteristics contin..
Produce Flowers
Flowers, the reproductive organs of all plants, distinguish
flowering plants (angiosperms) from seed plants
(gymnosperms).
Flowers that contain either male or female parts are called
imperfect, while those with both are called perfect flowers.
The stamen is the male reproductive part that is comprised of a
yellow anther that features a sac full of pollen, and the
delicate, long stem it rests on, called the filament.

9. Characteristics contin..
The female reproductive part is the pistil that is usually
found in the center of a flower. It is comprised of three
parts--the upper sticky part that catches and traps pollen
is the stigma; the tubular part called style that supports
the stigma; and the lower part that contains the ovule is
called the ovary.
The ovule develops into the seed when fertilized by
pollen grains. Self-pollinating or hermaphroditic plants
contain both male and female flower parts.

10. Characteristics contin..
Produce Fruits
Flowering plants bear one or several seeds enclosed in
fruit.
This fructification characteristic distinguishes
angiosperms from gymnosperms--seed plants that produce
seeds that are naked and do not lie within any fruit, such
as fir, pine and spruce trees.

11. Characteristics contin..
Angiosperms are comprised of the largest majority of
plants that bear seeds. Each plant variety of angiosperms
features a different size and shaped fruit which helps
identify and classify the particular species.
These fruits are available in a variety of colors and liven
up the landscape during growing season
