Archaea

• Prokaryotes
• Unicellular
• Most are heterotrophs
• Some autotrophs use chemosynthesis
• DNA, ribosomes, cell wall
• Cell wall does not contain peptidoglycan
• Asexual sexual reproduction

4
Types of Archaea

• Heat-loving
• Live in hot, acidic environments hot springs,
  thermal vents, around volcanoes
• Salt-loving
• Live in salty environments salt lakes, Dead Sea
• Methane-making
• Live in swamps and in human intestines
• Use CO2 during respiration and expel methane gas
  as waste

5
Eubacteria

• Prokaryotes
• Unicellular
• Most heterotrophs
• Cyanobacteria photosynthesize
• DNA, ribosomes, cell wall
• Cell wall contains peptidoglycan
• Asexual sexual reproduction

6
Shapes of Eubacteria

• Cocci sphere shaped
• Bacilli rod shaped
• Spirilli spiral shaped

7
Bacteria Human Diseases
Sexually transmitted Syphilis, gonorrhea, chlamydia
Respiratory Strep throat, pneumonia, whooping cough, anthrax
Skin Acne, boils, infections of wounds or burns
Digestive Tract Gastroenteritis, many types of food poisoning, cholera
Nervous system Botulism, tetanus, bacterial meningitis

Protists odds and ends

• Eukaryotes
• Some unicellular, some multicellular
• Some autotrophs, some heterotrophs
• Cell wall various composition
• Cellulose, algin, agar, calcium carbonate, silica
• Asexual sexual reproduction

10
Protists three types

• Animal-like - Protozoa - unicellular
• Heterotrophs eat other organisms
• Ex. Amoebas, ciliates, paramecia
• Plant-like Algae (one or more cells)
• Autotrophs photosynthesize
• Ex. Giant kelp, algae
• Fungus-like
• Heterotrophs absorb nutrients from decaying
  organisms
• Ex. Slime mold, water mold

11
Fungi

• Eukaryotes
• true nucleus membrane bound organelles
• Most multicellular (yeast unicellular)
• Heterotrophs digest food before consuming
• absorb nutrients from decaying organisms
• parasitic absorb nutrients from a living host
• mutualistic - lichens
• Cell wall made of chitin
• Asexual sexual reproduction

12
Plants

• Eukaryotes
• Multicellular
• Autotrophs
• Specialized tissues and organs
• Cell wall contains cellulose
• Sexual reproduction

13
Animals

• Eukaryotes
• Multicellular
• Heterotrophs
• Specialized tissues and organs
• Do not have a cell wall
• Sexual Reproduction
