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. 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






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






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






4. Produces digestive enzymes and the hormones insulin and glucagons






5. Organelle in which proteins are synthesized






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






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






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






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






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






11. Contracts or shortens making body parts move






12. Obsolete taxonomic group containing bacteria and cyanobacteria






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






14. 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






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






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






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






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






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






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






21. Brain and spinal cord






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






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






24. Holds tissues together






25. Organelle in which calcium levels are regulated






26. Connective - muscle - nervous - epithelial






27. Discovered mitosis






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






29. 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






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






31. 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.






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






33. Produce progesterone and estrogens - in addition to eggs






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






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






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






37. Attaches to bones and is responsible for voluntary movements






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






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






40. The basic structural and functional unit of all organisms






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






42. Stores solid waste products






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






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






45. Release of water from plants through stomata






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






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






48. Process that results in cell division to produce gametes






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






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