All living things can be classified into one of the five kingdoms.
Grouping by Similarities and Differences
Plants with Tubes
Forming Smaller Groups
Human Scientific Name
Unit A Chapter 2
Lesson 1, 2 & 3
No Bones, but a Vertebrate!
Animals with a Backbone
Animals Without a Backbone
Plants Without Tubes
There are about 8.7 million species of living things on Earth.
6.5 million are found on land and are mostly insects.
2.2 million are found in water.
With so many living things on Earth scientists need to be able to find things easily, so they group living things together that have similar features. This is called:
is the act of grouping things by using a set of rules
is the largest group into which living things are classified.
Is the kingdom in which the organisms are one celled and no nucleus.
Is the kingdom of organisms that are one celled and has a nucleus.
Is a many celled kingdom with organisms that has a nucleus and are in some ways similar to plants
Examples: Algae, Amoebas, Diatoms
Examples: Mushrooms, Yeasts, Molds
The name of the second smallest group of classification
The name of the smallest group of classification
Dog, or the non scientific name, is called the Common Name.
Monerans and Protists are similar because they are one celled organisms. The difference between the two is that one, the protists, has a nucleus and the moneran does not.
are animals that have a backbone
have hair and produce milk for their young.
have dry scaly skin.
have moist skin and no scales. Most begin life in water, but they live on land as adults.
vertebrates that live their entire life in the water.
are vertebrates with feathers.
are animals without a backbone.
and have legs with several joints.
The difference between a vertebrate and an invertebrate's skeleton is that one is inside the body and the other is often outside the body.
are plants that have tubes that in the roots, stems and leaves.
clogged tubes in the center of the trunk.
tubes that carry water and nutrients.
do not have tubes and water must soak into the plants and pass slowly from cell to cell along with it's food.
