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






2. 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.






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






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






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






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






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






8. Produce testosterone and sperm






9. 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






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






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






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






13. Any cell in a multicellular organism except the gametes






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






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






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






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






18. Sweat glands and sebaceous glands






19. Involuntary muscle that forms the contractile walls of the heart






20. Organelle containing genetic material






21. xylem and phloem; transport fluid and nutrients internally






22. Discovered mitosis






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






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






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






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






27. Useful for tearing and scratching






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






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






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






31. Produce progesterone and estrogens - in addition to eggs






32. Brain and spinal cord






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






34. 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






35. Largest organ in terms of surface area






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






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






38. Division of the cytoplasm during cell division






39. The basic structural and functional unit of all organisms






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






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






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






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






44. Contracts or shortens making body parts move






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






46. Stores solid waste products






47. Organelle in which calcium levels are regulated






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






49. 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.






50. 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
