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






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






3. Produces digestive enzymes and the hormones insulin and glucagons






4. 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






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






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






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






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






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






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






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






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






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






14. The basic structural and functional unit of all organisms






15. Organelle in which proteins are synthesized






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






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






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






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






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






21. 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






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






23. Largest organ in terms of surface area






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






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






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






27. 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.






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






29. Cells that form the outer surface of plants






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






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






32. Protects the body and holds in heat






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






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






36. Discovered meiosis






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






38. Useful for tearing and scratching






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






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






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






42. Supportive layer of tissue (sapwood or heartwood in trees) that carries water and nutrients up from the roots; dead cells






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






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






45. 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.






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






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






48. Attaches to bones and is responsible for voluntary movements






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






50. Produces and stores nutrients through photosynthesis
