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. Division of the cytoplasm during cell division






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






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






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






5. Release of water from plants through stomata






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






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






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






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






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






11. Any cell in a multicellular organism except the gametes






12. Produce testosterone and sperm






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






14. Process that results in cell division






15. Organelle in which calcium levels are regulated






16. Organelle in which proteins are synthesized






17. Plant with specialized tissue for conducting water and nutrients






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






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






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






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






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






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






24. The basic structural and functional unit of all organisms






25. Obsolete taxonomic group containing bacteria and cyanobacteria






26. Produce progesterone and estrogens - in addition to eggs






27. 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






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






29. 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






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






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






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






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






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






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






36. Organelle containing enzymes used in cell digestion






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






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






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






40. 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






41. Discovered mitosis






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






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






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






45. Covers organ surfaces (skin - airways - reproductive tract - inner lining of the digestive tract)






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






47. 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.






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






49. Sweat glands and sebaceous glands






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