1 Bacteria and Protists Ms. Dunn Forestbrook Middle Academic Standard Compare the body shapes of bacteria (spiral, coccus, and bacillus) and the body structures that protists (euglena, paramecium, amoeba) use for food gathering and locomotion.

2 What do I need to know? Be able to classify bacteria by their shape and protists (euglena, paramecium, amoeba) by the way they move and gather food. Bacteria are in the kingdom….. MONERA!!!!

3 Bacteria are: One-celled organisms. One-celled organisms. Categorized by their shape!!!!! Categorized by their shape!!!!! There are 3 basic bacterial shapes in the Kingdom Monera There are 3 basic bacterial shapes in the Kingdom Monera

4 1. Round – referred to as cocci 2. Rod Shaped- known as bacilli 3. Spiral – corkscrew shaped; known as spirilla

5 What do they look like and where do they live? bacteria Simplest organisms.asx (3 min. 39 sec.) How do we know they exist? We tapped their phone lines!!! science and bacteria (scientists).asx Okay, so we might need them for oil! Why dont we destroy them? Intro to Bacteria.asx

6 Protists Protists Protists are organisms that are classified into the kingdom Protista. Protists are organisms that are classified into the kingdom Protista. There is a lot of variety within the protists, they do share some common characteristics. There is a lot of variety within the protists, they do share some common characteristics. All protists: All protists: Have a nucleus with a nuclear membrane Have a nucleus with a nuclear membrane Are usually one-celled Are usually one-celled Live in moist environments Live in moist environments

7 Protists are grouped by the way they move and obtain food. Examples: Euglena, Paramecium & Amoeba Examples: Euglena, Paramecium & Amoeba Euglena- Euglena- Have a flagella Have a flagella Move by pulling themselves with their flagella Move by pulling themselves with their flagella characteristics of both plant and animal; contains chloroplasts that photosynthesize and can consume other organisms. characteristics of both plant and animal; contains chloroplasts that photosynthesize and can consume other organisms. euglena 43 sec.asx

8 2. Protists with Cilia (ex. Paramecium) Move by beating (flapping) tiny hair- like structures called cilia Move by beating (flapping) tiny hair- like structures called cilia Cilia act as tiny oars that allow the protist to move through its watery environment. Cilia act as tiny oars that allow the protist to move through its watery environment. Cilia also beat and help to capture food Cilia also beat and help to capture food

9 3. Protists with Pseudopods (ex. amoeba) Move by extending part of their bodies forward and then pulling the rest of their bodies forward Move by extending part of their bodies forward and then pulling the rest of their bodies forward Pseudopods- (false feet) finger-like structures that they project forward Pseudopods- (false feet) finger-like structures that they project forward also used to trap food also used to trap food
