Ciliophora • The ciliates get their name from the cilia that covers their body. • Cilia are short hair-like projections that are used for movement. • A paramecium is a common example of a ciliate
The paramecium has a pellicle, which is a folded outer layer that includes the cell membrane and other structures. • The pellicle includes a structure called a trichocysts used as protection. • When in danger, the trichocyst is used as a spike to damage the nearby cell. • Most paramecium have two nuclei, a larger one and a smaller one.
The larger nucleus is called the macronucleus and the smaller is the micronucleus. • A gullet is an indentation where the paramecium forces water through that may contain food. • The food is them held in a package in the cell called a vacuole. • After all usable food is removed from the vacuole, the vacuole merges with the cell wall and becomes an anal pore.
The paramecium used a pump system to remove extra water from inside the cell. This system is called a contractile vacuole.
Zoomastigina • This phylum use flagella to move through the water. • Flagella are long whip-like structures. • The zoomastigina usually get their food by absorbing it through the cell membrane. • Zoomastigina live in lakes and ponds. Some are parasites, others are symbionts.
Organisms that use flagella are called flagellates. • An example of a zoomastigina is Giardia.
Sporozoa • This phylum reproduces as spores. A sopre is a cell or group of cells enclosed in a protective coat. • These cells can attach to live cells and live as a parasite by stealing food from the host cell. • An example of a sporozoa is Plasmodium.
Plasmodium is the cause of the disease malaria. • Malaria is spread by mosquitoes. • An infected mosquito passes it on to humans when it bites by injecting saliva containing the spores. • These spores invade human lever cells until the cells burst releasing more spores to infect red blood cells.
The red blood cells can be taken in by a noninfected mosquito infecting it and making it able to pass the disease on to someone else.
