1. PROTISTS

2. KINGDOM PROTISTA Part of domain Eukarya Part of domain Eukarya Unicellular or simple Multicellular organisms Unicellular or simple Multicellular organisms Very diverse Very diverse kingdom but all are Eukaryotic Eukaryotic- has a nucleus

3. OBTAIN ENERGY Producers Producers Must have chloroplasts Must have chloroplasts Must use photosynthesis Must use photosynthesis Heterotrophs- organisms that cannot make their own food Heterotrophs- organisms that cannot make their own food Eat small living organisms (bacteria, yeast, or other protists) Eat small living organisms (bacteria, yeast, or other protists) Decomposers Decomposers Parasites- can invade fungi, plants, or animals Parasites- can invade fungi, plants, or animals

4. REPRODUCTION Some reproduce sexually and some asexually Some reproduce sexually and some asexually Asexual Reproduction- most protists reproduce asexually Asexual Reproduction- most protists reproduce asexually Reproduce by Binary Fission Reproduce by Binary Fission Multiple fission- more than two offspring from one parent Multiple fission- more than two offspring from one parent Sexual Reproduction- Sexual Reproduction- Paramecium reproduce by conjugation Paramecium reproduce by conjugation Conjugation- Two individuals join together and exchange genetic material by using a small second nucleus and then divide into four protists that have different combinations of genetic material Conjugation- Two individuals join together and exchange genetic material by using a small second nucleus and then divide into four protists that have different combinations of genetic material Some reproduce sexually and asexually Some reproduce sexually and asexually When conditions become unfavorable (little food or water) protists may produce sexually until conditions become favorable again When conditions become unfavorable (little food or water) protists may produce sexually until conditions become favorable again Reproductive Cycles- some protists may change forms many times Reproductive Cycles- some protists may change forms many times

5. PROTIST PRODUCERS (PLANT-LIKE) Red Algae- most of the world’s seaweeds. Red pigment allows them to absorb light that filters deep into the water. Red Algae can grow as deep as 260m below the surface of the water. Brown Algae- Seaweeds that are found in cooler climates. Green Algae- live in water or moist soil. They have chlorophyll which contributes to the green color.

6. PROTIST PRODUCERS (PLANT-LIKE) Diatoms- Found in salt and freshwater environment. Large percentage of phytoplankton. Dinoflagellates- Found in salt and fresh water. Have two whip-like strands called flagella. Flagella allows them to spin through the water. Euglenoids- They do not fit well in either protist group because some are consumers, some are producers, and some may be both!

7. HETEROTROPHIC PROTISTS (ANIMAL- LIKE) ALSO CALLED PROTOZOANS Ameobas- highly structured cells, eat bacteria and small protists, some are parasitic Zooflagellates- The One shown is a Giardia. They use flagella to move. Some are parasitic while others are mutualistic. Cilliates- The one shown is a Paramecium. They use cilia to move. They also use cilia for feeding.

8. HETEROTROPHIC PROTISTS (FUNGI- LIKE) Water Mold- Some are decomposers while others are parasites. Slime Mold- Giant cells that have many nuclei.
