| KINGDOM PROTISTA |
|
made up of a complex eukaryotic cell, |
|
some members make their own food, |
|
and some take food in from an outside source. |
|
Much more complicated than monerans |
|
Cell is somewhat like the whole body of a plant or animal "stuffed" into a single cell |
|
Has many specialized parts that carry out specific functions of living |
|
Example: We have legs for walking that are made of many cells. Protists use special parts of its SINGLE cell as "legs" |
|
Cells are so complex that they are often thousands of times larger the one of our own cells in our body. |
|
Covered by two shells that fit together like a pill box |
|
Float on the surfaces of fresh and salt water |
|
Food is stored within their cells as small drops of "oil" |
|
Much of our petroleum may be the stored food of diatoms that lived millions of years ago |
|
Have two whip-like tails for movement |
|
Make their own food |
|
Live on the surface of water |
|
Overpopulation can leave water smelling and tasting bad |
|
Biologists used to think they where plants or animals |
|
They are protists because of their specialized structures within each cell |
|
Have green pigments to make their own food through photosynthesis |
|
Have a kind of an "eye" |
|
Swim to move about |
|
Appear to have a mouthlike structure |
|
Pursues, catches and swallows its food |
|
Grouped into classes according to the way they move about (only 4 classes are shown below) |
|
1.Sarcodines | |
|
Resemble small masses of cloudy gelatin | |
|
Move by pushing out parts of their cell membranes | |
|
Fluids in these parts of the cell flow in the direction they are moving | |
|
2.Ciliates | |
|
Are covered by short hairlike structures called cilia | |
|
The cilia contract in "waves" to push the organism along | |
|
Cilia movement may "sweep" food into the mouthlike structures | |
|
3.Flagellates | |
|
Move by using one or two whiplike tales called flagella | |
|
Most live independently | |
|
Some live inside other organisms | |
|
Those that live inside other organisms may cause diseases such as African sleeping sickness | |
|
4.Sporozoans | |
|
Live inside other organisms | |
|
Most have no structures to move about | |
|
Depend on their "host" for transportation | |
|
Example: Malaria sporozoans are carried about in the human body by the bloodstream | |
