The Two GroupsThe Two Groups

Gymnosperms (with 3 phyla)Angiosperms (with 1 phylum)

Page 3: Vascular Plants With Seeds Divided into two Groups.

Phylum ConiferophytaPhylum Coniferophyta

Often called gymnospermsGymnosperms: the seed plants that do not first produce a flower before the seedMeans “naked seed” – produce seeds not covered by the walls of an ovary

Do not form flowers or fruits

Produce cones or cone-like structures

Conifer refers to the cones

All conifers produce seeds in cones

Page 4: Vascular Plants With Seeds Divided into two Groups.

Two Types of ConesTwo Types of Cones

Staminate and Ovulate

Page 5: Vascular Plants With Seeds Divided into two Groups.

Staminate ConesStaminate Cones

The pollen-producing cones

Small, green, and inconspicuous near the tips of the branches

Shed after the pollen season is over

Page 6: Vascular Plants With Seeds Divided into two Groups.

Ovulate ConesOvulate ConesThe seed-producing conesLarger than staminate conesSize range: 1-2 inchesWoody structures

consisting of layers of cone scales

Seeds develop between the cone scales

Seeds are generally winged

Pine Tree Life CyclePine Tree Life Cycle• Tree produces cones

• Pollen is carried by the wind from staminate cones to ovulate cones

• Pollen lands on the open scales of the ovulate cone

• The scales then close tightly (in many pines the cone begins to point downward

• Ovum is fertilized

• When the seeds are mature and environmental conditions are right, scales open and release seeds

Noteworthy Conifers: Douglas-firNoteworthy Conifers: Douglas-fir

The Douglas-fir, named for David Douglas, a 19th century Scottish botanist. Great strength, stiffness and moderate weight make it an invaluable timber product said to be stronger than concrete. Averaging up to 200' in height and six feet in diameter, heights of 325' and diameters of 15' can also be found.

Provide more than ¼ of the timber cut in the U.S.

Noteworthy Conifers: SequoiaNoteworthy Conifers: Sequoia

In central California

Some are among the oldest living things on earth (2,000 – 3,500 years)

273 feet tall

84 feet circumference

Bark 1 foot thick

Noteworthy Conifers: Noteworthy Conifers: Bristlecone PinesBristlecone Pines

The oldest living bristlecones are found in the White Mountains of California. The oldest known living tree, discovered in 1957, is a 4,723-year-old patriarch named Methuselah.

The oldest bristlecones are more than 4,000 years old. Egypt’s pyramids were under construction when these trees were seedlings!

Redwood trees are the tallest living things on earth.

Some grow more than 350 feet tall.


Characteristics of Seed Plants Most seed plants have leaves, stems, roots, and vascular tissue. They also produce seeds, which usually contain an embryo.
