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






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






4. Organelle containing enzymes used in cell digestion






5. Epidermis - vascular - ground






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






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






8. Stores and releases bile






9. Connective - muscle - nervous - epithelial






10. 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.






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






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






13. Brain and spinal cord






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






15. Discovered mitosis






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






17. 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






18. 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






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






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






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






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






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






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






26. Discovered meiosis






27. Plant with specialized tissue for conducting water and nutrients






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






29. Nutrient conducting plant tissue; formed like small tubules; living cells






30. 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






31. Produces and stores nutrients through photosynthesis






32. Organelle containing genetic material






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






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






35. Obsolete taxonomic group containing bacteria and cyanobacteria






36. Attaches to bones and is responsible for voluntary movements






37. The basic structural and functional unit of all organisms






38. Sweat glands and sebaceous glands






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






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






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






42. 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






43. Cells that form the outer surface of plants






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






45. Organelle in which proteins are synthesized






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






47. Any cell in a multicellular organism except the gametes






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






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






50. Division of the cytoplasm during cell division
