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. Holds tissues together






2. 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






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






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






5. Produces and stores nutrients through photosynthesis






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






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






8. 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






9. xylem and phloem; transport fluid and nutrients internally






10. 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






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






12. Process that results in cell division






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






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






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






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






17. Obsolete taxonomic group containing bacteria and cyanobacteria






18. The basic structural and functional unit of all organisms






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






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






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






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






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






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






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






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






27. Process that results in cell division to produce gametes






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






29. Include macrophages - B- cells - and T- cells






30. A haploid reproductive cell that unites with another haploid reproductive cell to form a zygote






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






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






33. 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






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






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






36. Sweat glands and sebaceous glands






37. Largest organ in terms of surface area






38. Attaches to bones and is responsible for voluntary movements






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






40. Epidermis - vascular - ground






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






42. Produce testosterone and sperm






43. Cells that form the outer surface of plants






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






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






46. Discovered mitosis






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






48. 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.






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






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