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. Chlorophyll containing plant cell organelle within which photosynthesis takes place






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






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






4. Organisms with cells that lack membranous - structurally discrete organelles






5. Connective - muscle - nervous - epithelial






6. Cells that form the outer surface of plants






7. 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.






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






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






10. 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






11. Organelle in which proteins are synthesized






12. Continuous sequence of growth (interphase) and division (mitosis) in a cell






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






14. The basic structural and functional unit of all organisms






15. Produce testosterone and sperm






16. Eukaryotic organism that is not an animal - a plant - or a fungus.






17. One of two identical 'sister' parts of a duplicated chromosome






18. Process that results in cell division






19. Cells that are able to differentiate into any type of cell in an organism






20. Structure within a cell that is responsible for a specific function






21. Organism that harnesses light energy to produce organic materials from carbon dioxide and water






22. Useful for tearing and scratching






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






24. Process that results in cell division to produce gametes






25. Your first line of defense against disease and helps regulate body temperature; skin - glands - hair - nails






26. Region of condense chromosome that looks pinched; where spindle fibers attach during meiosis and mitosis.






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






28. Stage of mitosis in which chromosomes condense into structures visible in a regular microscope






29. Strands of plant tissue containing xylem and phloem - sometimes surrounded by a fiber covering






30. Sweat glands and sebaceous glands






31. Third phase of mitosis and of meiosis I and II - in which the sister chromatids separate and move toward the poles of the spindle






32. Contracts or shortens making body parts move






33. Division of the cytoplasm during cell division






34. Holds tissues together






35. 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.






36. Stores and releases bile






37. Responsible for defending the body against disease - causing agents; white blood cells (macrophages - B- cells and T- cells) - lymph nodes






38. Detoxifies the blood - produces bile - and stores many vitamins and minerals






39. Organelle in which calcium levels are regulated






40. Produces hormones directly into the blood; pituitary gland - thyroid gland - adrenal glands - pancreas - ovaries - testes - thymus gland






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






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






43. In plants - a form of undifferentiated embryonic cell; exists in areas of plant growth like the root and shoot tips






44. Organelle containing genetic material






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






46. Any cell in a multicellular organism except the gametes






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






48. Located in the neck area. Releases thyroxin - which regulates the body's metabolic rate.






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






50. Obsolete taxonomic group containing bacteria and cyanobacteria
