Unit 5: Plantae Classification 23-24

These types of plants are able to grow taller because of the added support and faster nutrient transport of xylem and phloem.

• Seedless plants

• Vascular plants

• Bryophytes

• Nonvascular plants

• Stay short and close to the ground

• Gymnosperms

Nonvascular plants must live in moist environments and are unable to grow very tall. What factor contributes to these characteristics?

• They do not have vascular tissue that can transport water.

• They have a genetic disease that affects their ability to grow.

• They are made of xylem and phloem so they must be close to water.

• They must use all of their nutrients to produce seeds and therefore cannot grow taller.

How would this plant be classified?

Conifers are an example of what type of plant?

• Gymnosperm

• Angiosperm

• Deciduous

Which group of plants is known for having flowers and producing seeds enclosed within a fruit?

• Gymnosperms

• Angiosperms

• Bryophytes

• Ferns

Owen looks at five plants. He classifies a fern, moss, and pine tree in one group. He classifies an orange tree and sunflowers in another group. Which characteristics did Owen use to classify the plants?

• woody stems and soft stems

• long, thin leaves and wide, round leaves

• flowering plants and non-flowering plants

• Plants that grow on rocks and plants that grow in soil

The table shows the characteristics of several different plants. Which two plants in the table could be grouped together based upon their characteristics?

• Rose and algae could be grouped together as a vascular plant since they have roots, stems, and leaves.

• Pine tree and rose could be grouped together as a vascular plant since they have roots, stems, and leaves.

• Fern and pine tree could be grouped together as seeded vascular plants since they both reproduce with seeds.

• Fern and algae could be grouped together as non-seeded vascular plants since they both do not reproduce with seeds.
