Unit 8 Review- Organisms and Environments
6.12A&B– Prokaryotic and Eukaryotic Cells.
1. What is the smallest unit of living things? ___The Cell__.
2. Define the following terms:
Prokaryotic• Do not have a nucleus
• Few organelles
• Less complicated
• All bacteria
• Archaebacteria- oldest and in harsh conditions
• Eubacteria- Found everywhere
Eukaryotic• Have a nucleus
• Many organelles and more complex
• Can be single celled (just on cell) or multi-cellular
• All plants, animals, fungi, and protists are eukaryotic cells
3. What do Prokaryotic and Eukaryotic cells have in common?
• Both have DNA a cytoplasm and a cell membrane
• Both are microscopic
4. Label each image prokaryotic or eukaryotic:

5. Fill in the following table with the correct levels of taxonomic
classification in the first column, and a phrase you can use as a pneumonic
in the second column:

know about an organism before trying to sort it into a domain or
kingdom?
i. Number of Cells (Unicellular or Multicellular)
ii. Type of cells (Prokaryotic or Eukaryotic)
iii. Feeding Type (Autotroph or Heterotroph)

12. The following is a description of a fish tank ecosystem: In a glass fish
tank filled with 40 gallons of water, there lived a group of six goldfish. The
goldfish shared the tank with a starfish, some rocks, and a frog. The lightbulb at
the top of the tank kept it filled with bright light and also kept the temperature
of the tank warm. Some fungi grew on the side of the tank as well.
-Circle all the biotic factors of the fish tank’s ecosystem.
-Underline all the abiotic factors of the fish tank’s ecosystem.
-Name the population that lives in the tank’s ecosystem: Six Goldfish
