What do the cells of Protist and Bacteria look like? They are in a totally different kingdom, so their cells will be totally different! Standard 7-2.3: Compare the body shapes of bacteria (spiral, coccus, and bacillus) and the body structures that protists (euglena, paramecium, and amoeba) use for food gathering and locomotion.
Bacteria • Are classified into the Moneran (Archaebacteria and Eubacteria) Kingdom • Unicellular (Single-celled) organisms • Classified by body shape • Prokaryotic(does not have membrane bound organelles. • Less complex than plants and animals!
Spiral: corkscrew shaped Bacillus: rod-shaped (pill-shaped) Coccus: round-shaped Compare the body shapes of bacteria
Protists • Classified in the Protista Kingdom • A lot of variety within protists (plant like, fungus like and animal like), but they share some common characteristics. • You will learn about the animal like protist called protozoa( Proto: 1st -- Zoa: Animal) • Usually a one-celled organism that live in moist environments • Varies in how they obtain food and move
Move by pulling themselves with whip like structures called flagella Can have more than one flagella to help them move Has both plant and animal characteristics; contains chloroplasts (can make its own food) and can consume other organisms Euglena
Move by extending their bodies forward and then pulling the rest of their bodies forward The finger-like structures that they project forward are called pseudopods (false foot) The pseudopods are also used to capture food Amoeba
Move by beating tiny hair-like structures called cilia Cilia act like tiny oars Cilia help to capture food and directs the food toward a groove that functions like a mouth Paramecium
