The flashcards below were created by user ChathamBio144 on FreezingBlue Flashcards. What would you like to do?


  1. List 3 advantages that the move to terrestrial environments offered organisms (more than 2 are listed in the answer).
    • 1) more space available
    • 2) abundant sunlight
    • 3) unfiltered sunlight
    • 4) abundant carbon dioxide
    • 5) surfaces rich in mineral nutrients
    • 6) few pathogens
    • 7) few predators
  2. True or false (if false, provide the correct information):

    prokaryotic cells are within both the Archaea domain and the Algae domain.
    FALSE. They are in the Archaea and Bacteria domains (Algae is not a domain, it is a taxa within the Eukarya domain)
  3. Fill in the black:
    ___________________ in prokaryotes is circular and located in the nucleoid.
    The chromosome
  4. Fill in the blank:
    __________________ is the highest taxonomic level.
    The domain
  5. List 2 important ecological processes carried out by prokaryotes (more than 2 are listed in the answer).
    • 1. they act as decomposers of dead organisms
    • 2. they act as decomposers of waste products
    • 3. they help convert molecules to forms that can be used by other organisms
    • 4. they alter soil nutrient concentrations
    • 5. they produce atmospheric CO2
    • 6. they enter into beneficial symbiotic relationships with host organisms
  6. True or false (if false, provide the correct information):

    eukaryotic cells have a rigid cell wall.
    FALSE. They have a flexible cytoskeleton. Prokaryotes have a rigid cell wall.
  7. List 2 structures that may be found on the exterior cell wall of prokaryotic cells.
    • 1. cell capsule
    • 2. slime layer
    • 3. fimbriae
    • 4. endospores
  8. List two important ecological functions that plants serve.
    • 1. supply oxygen
    • 2. they are the ultimate source of most food eaten by land animals
    • 3. they are important in soil formation and nutrient cycling
    • 4. they act as carbon sequesters
  9. Fill in the blank:
    Fungi and plants are in the ________________ domain.
    Eukarya domain
  10. The chromosomes of which type of cell generally contains more proteins, prokaryotes or eukaryotes?
    Eukaryotes
  11. Give the energy source and carbon source of the follow prokaryote:

    Photoautotroph
    • energy: light
    • carbon: CO2
  12. Give the type of prokaryote that derives energy from light and carbon from organic compounds.
    Photoheterotroph
  13. Give the type of prokaryote that derives energy from light and carbon from organic compounds.
    Photoheterotroph
  14. True or false (if false, provide the correct information):

    some early plants were single-celled organisms
    FALSE. All plants are multicellular.
  15. Fill in the blank:
    ___________________ are prokaryotic cells that do not need oxygen for respiration, but they can use it if it is present.
    Facultative anaerobes
  16. What did most of the adaptations seen in early plants better enable them to do?
    Survive and reproduce on dry land
  17. Short answer (1-2 sentences):
    what are secondary compounds?
    Non-essential protective compounds (i.e., those not involved in growth, reproduction) produced by some plants.
  18. What structures in Eukaryotes replicate using a process similar to binary fission?
    Mitochondria and plastids
  19. Short answer (1 - 2 sentences ONLY):
    Briefly describe binary fission in prokaryotes.
    The cell replication process in which one cell divides into 2, 2 into 4, 4 into 8 and so on.
  20. True or false (if false, provide the correct information):

    genetic diversity is facilitated by rapid reproduction.
    TRUE
  21. Fill in the blank:
    ______________ and _____________ are two things that contribute to the extreme adaptability of prokaryotic cells.
    • possible responses include:
    • simple internal structure
    • simple external structure
    • variety of metabolic pathways
    • variety of ways to breath
    • simple reproduction process
