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






2. The basic structural and functional unit of all organisms






3. Obsolete taxonomic group containing bacteria and cyanobacteria






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






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






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






7. 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






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






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






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






11. Connective - muscle - nervous - epithelial






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






13. Produces digestive enzymes and the hormones insulin and glucagons






14. Epidermis - vascular - ground






15. Discovered meiosis






16. 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.






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






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






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






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






21. Cells that form the outer surface of plants






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






23. 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






24. Attaches to bones and is responsible for voluntary movements






25. Any cell in a multicellular organism except the gametes






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






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






28. Largest organ in terms of surface area






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






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






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






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






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






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






35. Organelle in which calcium levels are regulated






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






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






38. 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






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






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






41. Produce testosterone and sperm






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






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






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






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






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






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






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






49. Organelle containing genetic material






50. xylem and phloem; transport fluid and nutrients internally
