How Plants Are Classified Part 2: Reproduction
6-2.3: Compare the characteristic structures of various groups of plants (including vascular or
nonvascular, seed or spore-producing, flowering or cone-bearing, and monocot or dicot).

Essential Question
What are the main ways scientists classify plants?
You already know they are classified as vascular and non-vascular.
The following classification can also be used to group plants.

Seed Producing Plants• Seed-producing plants are plants that
reproduce through seeds. Seed plants make their own seeds.
• Seeds contain the plant embryo (the beginnings of roots, stems, and leaves) and stored food (cotyledons) and are surrounded by a seed coat. From those seeds, new plants grow.

Seed Producing Plants
• There are two major groups of seed-producing plants: cone-bearing plants (gymnosperm) and flowering plants (angiosperm).

Seed ProducersThe Cone-Bearing Plants
• Most cone-bearing plants are evergreen with needle-like leaves.
• Conifers never have flowers but produce seeds in cones. These seeds are said to be “naked”.
• Examples include pine, spruce, juniper, redwood, and cedar trees.

Seed Producers: The Flowering Plants
• Flowering plants differ from conifers because they grow their seeds inside an ovary, which is embedded in a flower.
• The flower then becomes a fruit containing the seeds.

Flowering Plants: Cont.
• Examples include most trees, shrubs, vines, flowers, fruits, vegetables, and legumes (beans).

The Non-Seed Producers: Spore Producing Plants
• Spore-producing plants are plants that produce spores for reproduction instead of seeds.
• Spores are much smaller than seeds. • Almost all flowerless plants produce spores. • Examples include mosses and ferns.
