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






2. Largest organ in terms of surface area






3. Organelle containing enzymes used in cell digestion






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






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






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






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






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






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






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






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






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






13. Stores and releases bile






14. 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.






15. Brain and spinal cord






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






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






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






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






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






21. 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.






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






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






24. Produce testosterone and sperm






25. Produces and stores nutrients through photosynthesis






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






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






28. Organelle in which proteins are synthesized






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






30. Process that results in cell division






31. 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.






32. Protects the body and holds in heat






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






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






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






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






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






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






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






40. Epidermis - vascular - ground






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






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






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






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






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






46. Organelle containing genetic material






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






48. Discovered meiosis






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






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