CLEP Natural Science

Subjects : clep, science
Instructions:
  • Answer 50 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. The complete genetic material contained in an individual






2. A substance that retards or stops enzymatic activity






3. The second phase of mitosis - during which the chromosomes line up across the center of the cell






4. Theory which suggests mitochondria and chloroplasts were once prokaryotic organisms in a symbiotic relationship with eykorytic cells






5. Packaged protein or other substance produced by golgi apparatus/endoplasmic reticulum






6. First step in releasing the energy of glucose - in which a molecule of glucose is broken into two molecules of pyruvic acid






7. Classification of plant which survives only a single season






8. Smallest unit of most living things






9. Sequence of DNA that codes for a protein and thus determines a trait






10. Process of building up complex materials (proteins) from simple materials






11. Passive transport of materials across a plasma membrane by transport proteins embedded in the plasma membrane






12. Hollow tubes of protein about 25 nanometers in diameter - support the cell and moves organelles within the cell






13. The stage of meiosis or mitosis when chromosomes move toward opposite ends of the nuclear spindle






14. Composed of a bilayer of lipids embedded with globular proteins






15. Breakdown of more complex substances into simpler ones with release of energy






16. Process by which a cell releases large amounts of material






17. Strong layer around the cell membrane in plants - algae - and some bacteria made of cellulose and lignin






18. Two identical chromosomes that split and contain the same genetic material






19. Matching Chromosomes that are similar but not identical






20. The part of an enzyme where the chemical reaction occurs






21. Different forms of a gene






22. Disk-like plates which are the site of photosynthesis in chloroplasts






23. The female part of a flower composed of ovary and style and stigma and ovules






24. The organic process whereby the DNA sequence in a gene is copied into mRNA






25. Classication of plant which produce seeds which are 'naked' (in cones)






26. The interchange of sections between pairing homologous chromosomes during the prophase of meiosis






27. Have tissues made of cells that transport water and nutrients throughout the plant






28. Used to examine tiny cell organelles






29. A long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix






30. Stores - packages and ships proteins






31. Part of stem where growth occurs - contains meristem tissue that is capable of quick growth






32. Living thing






33. Photosynthetic reaction in which carbon dioxide is attached to an organic compound (glucose - polysaccharides)






34. Powerhouse of the cell - organelle that is the site of ATP (energy) production






35. The male reproductive organ of a flower consisting of anther - filament - and pollen






36. Consists of DNA tightly coiled around proteins






37. Cells that lack a membrane-bound nucleus and membrane-bound organelles






38. Tubes - One of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope; play a role in cell division.






39. Pores which allows materials to move in and out of the cell nucleus






40. Stage of cellular respiration that finishes the breakdown of pyruvic acid molecules to carbon dioxide - releasing energy






41. Cell division which produces two identical cells






42. Numerous folds in the inner membrane of a mitochondrion - the site of cellular respiration






43. A cell having only one complete set of chromosomes






44. Stalk that supports the flower






45. Classification of plant which forms seeds inside a protective chamber called an ovary - inside a flower






46. Projections on cell membrane increase surface area






47. Particle made up of DNA - RNA - protein - and in some cases lipids that can only replicate only by infecting living cells






48. (adenosine triphosphate) main energy source that cells use for most of their work






49. Cell division that produces reproductive cells in sexually reproducing organisms






50. The regular sequence of growth and division that cells undergo
