Topic: Classification of Plants with Flower.
Objective: To identify the classification of plants with flower.
CLASS # 1 – U1
CHARACTERISTICS OF PLANTS WITH FLOWER
How are seed plants classified?
Seed plants are Vascular plants
that reproduce by making seeds.
A seed is a plant embryo
enclosed in a protective coating.
Seed plants also produce pollen,
a tiny structure in which sperm
forms. A sperm cell from pollen
fertilizes an egg cell, which
develops into an embryo inside a
seed. Seed plants are classified
based on whether or not their
seeds are enclosed in a fruit.
CHARACTERISTICS OF PLANTS WITH FLOWERS
Gymnosperms (JIM-nuh-spermz)
Gymnosperms are plants that produce seeds that are not enclosed in a fruit. This group
includes cycads (SY-kadz), ginkgoes (GING-kohz), and conifers.
Cycads
They produce seeds in large, woody structures called cones that
grow at the center of a thick trunk. They are found in the tropics
that have short stems and palm-like leaves and only 140 species
still exist.
Ginkgoes
They produce round, grape-like seeds that are not covered by a
cone. Ginkgo seeds smell like rotting butter. They are used in
traditional medicine and only the Ginkgo biloba is still alive today.
Conifers
They are the most common type of gymnosperm. This
group that includes pine trees, cedars, and redwoods, also
produce cones. The wood of conifer trees is used for
building and for paper products. Pine trees also produce a
sticky fluid called resin used to make soap, paint, and ink.
Angiosperms (AN-jee-uh-spermz)
Angiosperms are vascular plants that produce flowers, and fruits which surround and
protect seeds.
Angiosperms are the most abundant type of plant alive today.
At least, 160,000 living species of angiosperms are known, and new species are still being
discovered.
They can be found in almost every ecosystem.
Flowers are the reproductive structures of angiosperms. Flowers are typically made up of
sepals, petals, stamens, and a pistil.
