1. Protists- the hodge- podge group
Kingdom Protista
Protists- the hodge- podge group

2. Basics Eukaryotic 3 groups- animal like -Protozoans plant like- Algae
fungi like- Slime molds
Evolved from a symbiotic relationship: 1 prokaryote engulfed another (like a mitochondrial or chloroplast like cell) ENDOSYMBIOSIS

3. Protozoans- animal like
HOW THEY MOVE
PSEUDOPOD
FLAGELLA
CILIA
SPORES
(SPOROZOAN)
Example
Sarcodines
Amoeba
Zooflagellates
Giardia
Ciliates
Paramecium
Plasmodium
Environment
Salt and fresh water
1.Streams
2. Gut of termite
3. Parasite in human DT
Ponds and streams
Gut of mosquito/
blood of humans
Special
Structures
Contractile vacuole- pumps out excess water
Help digest cellulose
Ingest food through oral groove and gullet
Macro and micronucleus
Produce spores-need intermediate host like mosquito
Diseases
Amoebic dysentery
Giardiasis
Malaria

4. Pseudopods stream in different directions to make amoeba move.
Single celled
Pseudopods surround food and engulf it

5. Giardia Can cause giardiasis. Usually from contaminated water.
Called backpackers diarrhea

6. Paramecium
Use cilia to sweep food into oral groove and then digest in the gullet.
Has 2 nuclei- I macro and 1 micro

7. Plasmodium Causes malaria Lives in gut of mosquito
Mosquito bites human
Injects some spores- they germinate and live in the blood

8. ALGAE-Plant like Contain chlorophyll or other pigment
Can be unicellular, multicellular or colonial
7 types

9. Euglenophyte: Euglena
Unique because they can do photosynthesis and ingest food(heterotrophic).
Has an EYESPOT which helps detect light so it can swim towards it to photosynthesize
Has a flagella for movement
Pellicle- thick outer covering

10. Chrysophyte:Golden Algae
Many unicellular
Some colonial
Gold colored chloroplast

11. Diatoms Contain chlorophyll Photosynthetic
Shell made of SILICA- used for abrasives in cleansers like toothpaste
Also called phytoplankton

12. Dinoflagellates Cell wall contains cellulose Contain chlorophyll
Also have another pigment called carotenoid(orange color)
Cause Red Tide- due to overgrowth in the ocean. Produces a toxin that is harmful to sea life and humans

13. Red Algae Phylum Rhodophyta Multicellular Marine sea weed
Has no roots, stems, or leaves
Main structure called a thallus
Has Chlorophyll a and phycobilins that help harvest light at deep depths.

14. Brown Algae Phylum Phaeophyta Multicellular
Contain chlorophyll and a brown pigment- FUROXANTHIN
Kelp
Have air bladders to keep them afloat

15. Green Algae Phylum Chlorophyta Most live in fresh water
Can be unicellular or multicellular
Spyrogyra-multicellular
Volvox is a colonial green algae

16. Uses for Algae Base of the food chain Produce O Sushi:nori
Smoothener in foods like ice cream and pudding
Industrial uses: plastics, waxes, deodorant, paint, agar( material used to grow bacteria)

17. Fungi like – Slime Molds and Water Molds
Live in moist, cool environment
Watery molds- Oomycota
