Flagella
A whip-like structure used for movement in organisms like Euglena
Cilia
Hair-like projections on the cell surface used for locamotion or movement.
pseudopod
A temporary, foot-like extension of a cell, used for locomotion or engulfing food
nucleus
Control center of the cell which contains genetic material (DNA).
eukaryotic
A cell characterized by the presence of a nucleus and other membrane-bound organelles. Eukaryotes can be unicellular (protists) or multicellular (fungi, plants and animals).
chloroplast
A structure in the cells of plants and some protists that captures energy from sunlight and uses it to produce food.
contractile vacuole
Organelle that pumps water out of the cell of some protists such as the paramecium
oral groove
A depressed region around the mouth of some ciliate protozoans, such as paramecia, used to obtain food
eye spot
A light detecting organelle found in unicellular organisms.
organelle
A tiny cell structure that carries out a specific function within the cell
heterotrophic
An organism that cannot make its own food but must obtain energy by eating other organisms.
autotrophic
An organism that can make its own food through a process like photosynthesis or chemosynthesis.
asexual reproduction
Process by which a single parent reproduces by itself, resulting in gentically identical offspring
sexual reproduction
A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents
volvox
Colonial green algae held together in a secretion of gelatinous material, resembling hollow ball
paramecium
A ciliated protist that lives in fresh water and eats other tiny organisms for food using an oral groove.
amoeba
A type of protist characterized by great flexibility and the presence of one or more pseu.
euglena
A protist that has characteristics of plants and animals and has an "eyespot" that responds to light and uses a flagella for movement
protist
kingdom composed of eukaryotes that are not classified as plants, animals, or funi
