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. Responsible for storing food and initiating the digestion of proteins






2. Discovered mitosis






3. Sweat glands and sebaceous glands






4. 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






5. Protects the body and holds in heat






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






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






8. Brain and spinal cord






9. Contracts or shortens making body parts move






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






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






12. 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.






13. Useful for tearing and scratching






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






15. Produce progesterone and estrogens - in addition to eggs






16. Process that results in cell division to produce gametes






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






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






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






20. 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






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






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






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






24. Process that results in cell division






25. Division of the cytoplasm during cell division






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






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






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






29. 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






30. 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.






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






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






33. Organelle containing enzymes used in cell digestion






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






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






36. 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






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






38. Produces and stores nutrients through photosynthesis






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






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






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






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






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






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






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






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






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






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






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






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