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






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






3. 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.






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






5. Discovered that animal tissues are made of cells.






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






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






8. Cells that do not contain membrane enclosed compartments. Single celled organsms roughly one micrometer long. Attached Flagellum gives the organism mobility.






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






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






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






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






13. Scientist who successfully disproved spontaneous generation.






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






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






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






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






18. Discovered that plant tissues are made of cells.






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