Paramecium Protist that eats others with a gullet and moves using cilia.
Euglena Protist with chloroplasts and a single flagella.
Volvox Protist that lives in colonies and uses photosynthesis to make sugar.
cilia organelle that looks like hair, helps some protists move around.
flagellum organelle that is a whip-like structure used for moving around.
Gullet A mouth like organelle of some protists.
Contractile Vacuole an organelle that shoots out or excretes extra water and waste.

organelle a structure with a function in a cell.
mitochondria organelle known as the powerhouse of the cell. It takes sugar and oxygen and burns it for energy, making CO2 and Water in the process.
Ribosome Organelle that makes proteins, the factory of the cell.
Nucleus The organelle in the center of the cell. The brain that stores DNA
Nucleolus Organelle inside of the nucleus that creates ribosomes.
Cell Wall Organelle only for plant cells, built outside the cell to provide support and protection. Allows trees to grow really tall.
Lysosome organelle that recycles older or broken parts inside a cell.
Eye Spot An organelle that helps some cells detect changes in light levels.
