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






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






3. Stores and releases bile






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






5. Located close to the kidneys. Responsible for releasing adrenaline - a hormone that produces the flight or fight response.






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






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






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






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






10. Involuntary muscle that forms the contractile walls of the heart






11. Attaches to bones and is responsible for voluntary movements






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






13. Organelle in which proteins are synthesized






14. Contracts or shortens making body parts move






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






16. Discovered meiosis






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






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






19. The basic structural and functional unit of all organisms






20. xylem and phloem; transport fluid and nutrients internally






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






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






23. Organisms with cells that have a membrane - bound nucleus and other well - structured organelles






24. So named because it lacks striations. Involuntary muscle found along the walls of the digestive tract - bladder - arteries - and other internal organs.






25. Any cell in a multicellular organism except the gametes






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






27. 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.






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






29. 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.






30. Microtubule within a cell's nucleus; joined to one of the poles during cell division






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






32. Discovered mitosis






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






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






35. Organelles critical to protein synthesis found in the cytoplasm - joined to the endoplasmic reticulum - and within the mitochondria






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






37. Largest organ in terms of surface area






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






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






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






41. 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






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






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






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






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






46. Produces and stores nutrients through photosynthesis






47. Obsolete taxonomic group containing bacteria and cyanobacteria






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






49. Dense portion of the nucleus; contains RNA and is involved in protein synthesis






50. Holds tissues together
