CSET Science: Subtest I Cell And Organismal Biology

Subjects : cset, 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. Organisms with cells that lack membranous - structurally discrete organelles






2. Attaches to bones and is responsible for voluntary movements






3. Produce progesterone and estrogens - in addition to eggs






4. Pores underneath plant leaves used to exchange carbon dioxide and oxygen






5. Is actually a lymphoid organ in the neck or upper chest of all vertebrates. It is essential in the normal development of the immune system.






6. Organelle that 'packages' proteins to be secreted from the cell






7. Any cell in a multicellular organism except the gametes






8. Discovered mitosis






9. Responsible for the breakdown and absorption of food and the removal of solid waste; include the alimentary canal (mouth - esophagus - stomach - small intestine - large intestine - colon/ rectum) and the accessory organs (liver - pancreas - gall blad






10. Sweat glands and sebaceous glands






11. Discovered meiosis






12. Ability of a cell to differentiate into multiple different types of cells






13. A complex polymer that fills the spaces in the cell wall - conferring mechanical strength to the cell wall and the plant as a whole.






14. Organelle composed of microtubules within the nucleus that helps ensure that duplicated chromosomes are evenly distributed to the daughter cells






15. Organelle in which lipids and steroids are produced - carbohydrates and steroids are metabolized - and calcium concentration - drug detoxification - and attachment of cell membrane receptors are regulated.






16. Responsible for releasing several tropic hormones - which regulate the activity of other endocrine glands






17. A doubled rod of condensed chromatin; contains DNA that carries genetic information.






18. Produce testosterone and sperm






19. Small sac within a cell formed by pinching of some membrane; can contain waste - products the cell is taking in - and secretions the cell is exporting






20. The process by which a cell becomes specialized for a specific structure or function






21. Tiny nodules found all over the body. They contain a colorless fluid called lymph.






22. Made up of celluolose - protein - and lignin - and allows pressure in plant cells to increase without the cell bursting.






23. Responsible for providing voluntary and involuntary movement; cardiac - skeletal - smooth






24. Covers organ surfaces (skin - airways - reproductive tract - inner lining of the digestive tract)






25. Largest organ in terms of surface area






26. Organelle in which proteins are synthesized






27. Nutrient conducting plant tissue; formed like small tubules; living cells






28. The spore - producing individual or phase in the life cycle of a plant having alternation of generations






29. Process that results in cell division to produce gametes






30. Responsible for storing food and initiating the digestion of proteins






31. Chlorophyll containing plant cell organelle within which photosynthesis takes place






32. An extensive membrane network of cisternae (sac - like structures) held together by the cytoskeleton that encloses the cisternal space (or lumen) from the cytosol and is continuous with the perinuclear space. Three types: RER - SER - SR






33. Produces and stores nutrients through photosynthesis






34. One of the cells formed from a parents cell after mitosis






35. Division of the cytoplasm during cell division






36. Release of water from plants through stomata






37. Membrane - bound and fluid filled organelle in plant of fungal cells; also found in some bacterial - protist - and animal cells






38. Responsible for digesting and absorbing the extracted vital nutrients from food






39. Group of similarly constructed cells that perform the same function within a multicellular organism






40. Contracts or shortens making body parts move






41. All of the nerves leading to and from the central nervous system






42. Responsible for transporting materials throughout the body: heart - blood (red - white - platelets) - blood vessels (arteries - vein - capillaries)






43. Stage in which chromosomes are aligned in the center of the cell






44. Connections between plant cells that allow fluids and nutrients to be shared






45. In the life cycle of a plant or alga undergoing alternation of generations - a meiotically produced haploid cell that divides mitotically - generating a multicellular individual - the gametophyte - without fusing with another cell.






46. The basic structural and functional unit of all organisms






47. Stores solid waste products






48. Plants with no phloem - xylem - roots - stems - or leaves; not as large or intricate as vascular plants






49. Last stage of mitosis - in which the cell membrane begins to pinch the cell in two - cytokinesis begins - and the nuclear membrane forms around the chromosomes






50. Circulates through the vessels of the lymphatic system - which in turn assists the immune system.
