CLEP Biology: Cell Structure And Function

Subjects : clep, science, biology
Instructions:
  • Answer 19 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Cells that do not contain membrane enclosed compartments. Single celled organsms roughly one micrometer long. Attached Flagellum gives the organism mobility.






2. Cells containing membrane enclosed compartments. Typically 10-30 micrometers.






3. Challenged the notion of spontaneous generation by postulating that cells come from pre-existing cells.






4. Unique to eukaryotic cells; anchors the organelles in place in the cell - includes three types of fibers Microfilaments - microtubules and intermediate filaments.






5. Discovered that plant tissues are made of cells.






6. In plant cells only - this organelle is responsible for photosynthesis






7. This type of cell is made up of dendrites and axons.






8. Scientist who successfully disproved spontaneous generation.






9. One of the three broad categories into which all organisms are grouped. Eukarya - Archaea - and Bacteria.






10. Organelle responsible for the synthesis of RNA into Proteins.






11. A distinct structure or compartment within a eukaryotic cell that performs specific tasks.






12. Membrane enclosed sacs containing digestive enzymes that break down proteins - carbohydrates - and fats.






13. The simplest unit of biological organization. Term coined by Robert Hooke who invented the first microscope. Basic unit of life.






14. Discovered that animal tissues are made of cells.






15. In plant cells only - this supports the cell shape and protects the cell.






16. Organelle that sorts and modifies proteins from ER and prepares them for transport to specific parts of the cell.






17. The barrier between cells made of a bilayer or phospholipid molecules.






18. In plants only - a membrane enclosed region that serves as a toxic waste dump. The deterioration of these hastens the death of the cell and the plant.






19. The main sites of energy transformation in eukaryotic animal cells.
