1. Protist and Fungi
You will be able to explain how protists and fungi are similar and different than other common microscopic organisms.

2. Prokaryote (Bacteria Cell)
Can Not See Nucleus
Much smaller than Eukaryote cells
No visible organelles
Contains DNA and RNA

3. Eukaryote Cells: Protists and Fungi
Much larger
Can See Nucleus (Brain of Cell) and organelles
Complex cell can do more than Prokayote
Has Specialized Functions in multi-cellular organisms
Contains DNA and RNA
DNA mainly in nucleus

4. Protist Characteristics
Much larger than bacteria and viruses
Animal-like though 1 makes its food by photosynthesis
Made up of eukaryote cells—You can see nucleus and organelles (unlike prokaryote bacteria)
Most unicellular but some are multi-cellular ( certain algae )
Only found in moist environments (water)
4 basic types of Protists
Reproduce using Fission (cloning/asexual) and Fussion (conjucation/sexual)
Nucleus
Amoeba
Psuedopodia
Nucleus

5. Protist 1: Paramecium Eukaryote- can see nucleus and organelles
Covered in cilia
Found in Water
Has 2 Nucleuses
Feeds on other protists (algae and Euglena)
Contracting Vacuole
Macronucleus
Micronucleus

6. Protist 2: Ameoba Eukaryote- can See organelles and Nucleus
Move with Pseudopodia
Found in bottom in the sediment of most water systems
Engulfs food by surrounding it
Causes diseases such as malaria, and dysentery and rare form eats brain of humans!
Pseudopodia
Nucleus

7. Protist 3: Volvox and Algae
Volvox (colony of algae cells)
Eukaryote- can See Nucleus and organelles
Green organelles called chloroplasts
Autotrophic-makes own food
Some live as colony (Volvox)
Some deadly release toxin known as the Red Tide
Red Tide

8. Protist 4: Euglena Eukaryote- can see Nucleus and organelles
Is both Plant and Animal; makes and eats food
Found in water
Has long tail called flagellum
Has “eyespot” to detect light (Stigma)
Green color from chloroplasts

9. Protist or Protozoans: 4 Basic Traits
Most Animal like
Lack cell walls and most heterotrophic
Move with cilia, pseudopodia (little feet) or flagellum
Found mainly in water
Cause Diseases such as Malaria and Dysentery

10. Algae Eukaryote organisms Not True Plants
Can be unicelled or multicellular
Produce up to 60% of the world’s oxygen

11. Slime Molds
Slime mold is a broad term describing fungus-like organisms that use spores to reproduce
Slime molds were formerly classified as fungi, but are no longer considered part of this kingdom.
Their common name refers to part of some of these organisms' life cycles where they can appear as gelatinous "slime".

12. Mold/Fungi Characteristics
Eukaryotes – can see nucleus and organelles
Have cell walls made of chitin (insect skeleton material)
Unable to make their own food so act as parasites: absorb food from other living/decaying things
use spores to reproduce
Like to grow in warm moist areas: ARCH ENEMY of BACTERIA

13. Cell structure
Size is anywhere from tiny unicellular to large multicellular

14. Reproduction
Lightweight spores are surrounded by a protective covering and can be carried easily through the air or water to new sites

15. Example
Mushrooms
Athletes foot
Mold

16. Closing of Microlife How do we protect ourselves from these pathogens?
Virus
Bacteria
Protists
Mold/Fungi
What type of medicines work against them?
Vaccines
Antibiotics
Chlorine in water
Antifungal medicines

17. What makes pathogens dangerous?
Fact One:
How easily it spreads from organism to organism (person to person)
Fact Two:
How rapidly can the Pathogen reproduce itself

18. Preventing Spread of Disease
Active Immunity- your body is producing antibodies to fight it off. (Vaccine or prior exposure)
Passive Immunity- you are injected with antibodies from another organism to fight it off; allows time for your body to find and make antibodies before you become ill

19. Biotechnology
Biotechnology- use of living organisms to produce products for human use.
Products can be such as genetically altered food such as milk, corn, and tomatoes
Piggybacked viruses, using a harmless virus to produce capsid of a more harmful one. Idea is that harmless virus will makes “protein coat” of harmful one so that your body could make antibodies for the “bad one”
