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 Can Not See Nucleus Much smaller than Eukaryote cells Much smaller than Eukaryote cells No visible organelles No visible organelles Contains DNA and RNA Contains DNA and RNA

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

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

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

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

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

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

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

10 Algae Eukaryote organisms Eukaryote organisms Not True Plants Not True Plants Can be unicelled or multicellular Can be unicelled or multicellular Produce up to 60% of the world’s oxygen 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 mold is a broad term describing fungus-like organisms that use spores to reproducefungus Slime molds were formerly classified as fungi, but are no longer considered part of this kingdom. 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". 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 Eukaryotes – can see nucleus and organelles Have cell walls made of chitin (insect skeleton material) 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 Unable to make their own food so act as parasites: absorb food from other living/decaying things use spores to reproduce use spores to reproduce Like to grow in warm moist areas: ARCH ENEMY of BACTERIA Like to grow in warm moist areas: ARCH ENEMY of BACTERIA

13 Cell structure Size is anywhere from tiny unicellular to large multicellular 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 Lightweight spores are surrounded by a protective covering and can be carried easily through the air or water to new sites

15 Example Mushrooms Mushrooms Athletes foot Athletes foot Mold Mold

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

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