Bihmidine section Flashcards
Prokaryote Characteristics
Lack organelles Unicellular Outer cell wall, cytoplasm and flagella/fimbriae Lacks membrane bound organelles Can have plasmids
Archaea Characteristics
Prokaryotic
Eukaryotic Characteristics
Eukaryotic Variety of organelles Contains nucleus Uni or Multicellular Includes protists, plants, humans and fungi
Homologous structures
Similar physical features that share a common evolutionary past and overlap
Ex. Bat and Birds wings
Analogous structures
Do not share evolutionary history
Similar characteristics occur due to environmental constraints
Ex. Bee wings being similar to bat/bird wings
Classification Levels in order
King Phillip Came Over For Greens and Spinach
Prokaryotic cell structures and functions
No nucleus
Flagellum
Cell wall (B & A different though)
4 Modes of Prokaryote Reproduction
Transduction
Conjugation
Binary fission
Transformation
Bacterial Metabolism Types
Autotrophic vs Heterotrophic
Facultative
Anaerobes
Aerobes
Protist Characteristics
Anything but animals, fungi or plants
Eukaryotic characteristics
Modes of Motility in Protists
Flagellum (Euglena)
Cilia (Paramecium)
Pseudopods (Amoeba)
Fungi Characteristics (including nutrition)
Have mycelia
Do NOT have chloroplasts or chlorophyll
Heterotrophs
Use enzymes to break down complex molecules to smaller organic compounds
Fungi Modes of Reproduction
Asexual: Fragmentation, Budding and Spores
Sexual: Plasmogamy, Karyogamy, Meiosis
Fungi Phyla and Characteristics of each
Chytridiomycota (chytrids)
-retained flagella, unicellular and aquatic
Zygomycota (conjugated fungi)
-bread mold, saprobes, few are parasites
Basidiomycota (club fungi)
- club shaped basidia (repro organs), gills
Ascomycota (sac fungi)
- forms ascus, yeast, truffles, rice ferment.
Glomeromycota
Ecological Importance of Fungi
Important decomposers
Produce exoenzymes
Important in ecosystems (bracket fungi)
Interactions w other organisms (shelf fungi)
