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. Organelle in which proteins are synthesized






2. Supportive layer of tissue (sapwood or heartwood in trees) that carries water and nutrients up from the roots; dead cells






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






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






5. Makes up the brain - cranial nerves - spinal cord - and peripheral nervous system






6. The basic structural and functional unit of all organisms






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






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






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






10. Process that results in cell division






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






12. Produce testosterone and sperm






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






14. Cells that form the outer surface of plants






15. Responsible for extracting water and essential vitamins from the digested food






16. 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.






17. Useful for tearing and scratching






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






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






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






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






22. Organelle containing genetic material






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






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






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






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






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






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






29. Organelle in eukaryotic cells that produces chemical energy; have their own DNA and may have evolved from a symbiotic relationship between a primitive eukaryotic organism and a primitive bacteria






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






31. Division of the cytoplasm during cell division






32. Epidermis - vascular - ground






33. Thin layer of plant tissue just below the bark which produces the xylem






34. Sweat glands and sebaceous glands






35. Stores solid waste products






36. 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.






37. A cell that can differentiate into many different cell types






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






39. Obsolete taxonomic group containing bacteria and cyanobacteria






40. 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






41. Largest organ in terms of surface area






42. Produces and stores nutrients through photosynthesis






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






44. Responsible for the collection - transference - and the processing of external and internal information throughout the body; central nervous system - peripheral nervous system






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






46. Process that results in cell division to produce gametes






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






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






49. Release of water from plants through stomata






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