Animal Classification
This group of animals has a backbone.
What are vertebrates?
These plants produce flowers and seeds.
What are angiosperms?
Scientists classify organisms by looking at these observable traits.
What are characteristics?
This organism has six legs, wings, and no backbone.
What is an insect?
Scientists ask questions and gather this before classifying organisms.
What is evidence?
A frog, fish, and eagle belong to this major animal group.
What are vertebrates?
Pine trees belong to this plant group because they produce seeds in cones.
What are gymnosperms?
Scientists use this tool with a series of yes-or-no questions to identify organisms.
What is a dichotomous key?
This organism has eight legs and no backbone.
What is an arachnid?
If an organism has no backbone, scientists can immediately place it into this group.
What is an invertebrate?
Scientists use this body structure first when deciding if an animal is a vertebrate or invertebrate.
What is a backbone?
These plants reproduce using spores instead of seeds and have roots, stems, and leaves.
What are ferns?
This is more useful for classifying animals than the color of their body.
What is body structure?
This plant has flowers, roots, stems, leaves, and seeds.
What is an angiosperm?
The first question on a dichotomous key should focus on this type of characteristic.
What is a major characteristic or body structure?
An insect, spider, and snail all belong to this group because they lack a backbone.
What are invertebrates?
This plant group has no true roots, stems, or leaves and often grows in damp places.
What are mosses?
Two animals live in the ocean. One has a backbone and one does not. Scientists would place them in these different groups.
What are vertebrate and invertebrate groups?
This plant reproduces with spores and does not produce seeds.
What is a fern?
A student says all green plants belong in the same group. Scientists would disagree because they also look at these traits.
What are seeds, flowers, cones, roots, stems, or spores?
A newly discovered animal has fur, gives birth to live young, and feeds its babies milk. Scientists would classify it into this vertebrate group.
What is a mammal?
Scientists found a plant that produces seeds but no flowers. It most likely belongs to this plant group.
What are gymnosperms?
Scientists classify organisms to show how living things are related and to make them easier to do this.
What is identify or study?
This organism has a backbone, feathers, and lays eggs.
What is a bird?
Explain why scientists use classification systems instead of memorizing every organism separately.
What is classification helps organize organisms, identify new species, and show relationships among living things?
