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 digesting and absorbing the extracted vital nutrients from food






2. Discovered meiosis






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






4. Cells that form the outer surface of plants






5. Organelle composed of microtubules within the nucleus that helps ensure that duplicated chromosomes are evenly distributed to the daughter cells






6. xylem and phloem; transport fluid and nutrients internally






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






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






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






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






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






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






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






14. Division of the cytoplasm during cell division






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






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






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






18. 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






19. Brain and spinal cord






20. Produces and stores nutrients through photosynthesis






21. Any cell in a multicellular organism except the gametes






22. Organelle in which calcium levels are regulated






23. 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






24. Contracts or shortens making body parts move






25. 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






26. Attaches to bones and is responsible for voluntary movements






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






28. Process that results in cell division to produce gametes






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






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






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






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






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






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






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






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






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






38. The basic structural and functional unit of all organisms






39. Organelle containing enzymes used in cell digestion






40. Discovered mitosis






41. 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






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






43. Produces digestive enzymes and the hormones insulin and glucagons






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






45. Connective - muscle - nervous - epithelial






46. Epidermis - vascular - ground






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






48. 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.






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






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