1. Protists: Amoebas, Cellular Slime Molds, Chytrids, Ciliates, and Diatoms
The Zach Haltvick

2. Protists Unicellular May live in colonies
Have no distinct characteristics of plants, animals, or fungi
Many used to be classified as plants, animals, or fungi
May live in colonies
Move around by waving tiny hairs
Energy
Absorption from surrounding area
Predation of plants or animals
Photosynthesis

3. Amoebas Pond Water Has no permanent shape Reproduction
Body is constantly changing
Trap food particles
Cell parts become fluid and form feet around little bits of food
Once the food is surrounded by the feet, the amoeba encloses itself around the food
Eat protozoans and tiny animals
Reproduction
Simply divide in two

4. Cellular Slime Molds
Spend most of their lives as individual cells, but……
Release chemical signal
Cells come together into big swarms
Resembles a slug
Crawls around ingesting food until it finds a warm, sunny location
Reproduction
Two haploids fuse
Engulf neighboring slime molds
Forms a single organism: a macrocyst
Undergoes meiosis and mitosis
Releases new, haploid individuals

5. Chytrids Live mostly in freshwater, but Feed on decaying matter
Can be found in soil and saltwater
Feed on decaying matter
Can also be parasites to:
Algae
Fungi
Plants
Microscopic animals
Reproduction
Asexually
Form spores
Spores swim around, and develop when they stop moving

6. Ciliates Live in all environments of water
Covered with short, dense hairs
Use to move through the water and trap food
Eat bacteria and other single-celled organisms
Some by a “mouth”
Some by absorption
Asexual reproduction
Micronucleus undergoes mitosis
Splits in half

7. Diatoms Freshwater, saltwater, moist soil, or moist surface of plants.
All are enclosed in a shell made of silica
The diatom secretes the silica
Usually live singly, but can exist in colonies
Reproduce asexually
Cell division

8. Life Cycle Life Cycle of a Cellular Slime Mold
Begins with a haploid spore
Produced by meiosis
Germinated spores become either a myxamoeba cell or a flagellated swarm cell
Two cells fuse together in cellular fusion, then nuclear fusion
The result is a diploid zygote
Transforms into a developing plasmodium
Diploid nuclei divide = plasmodium gets bigger
