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






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






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






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






5. Brain and spinal cord






6. 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.






7. Stores and releases bile






8. Release of water from plants through stomata






9. Protects the body and holds in heat






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






11. Stores solid waste products






12. Division of the cytoplasm during cell division






13. Obsolete taxonomic group containing bacteria and cyanobacteria






14. Contracts or shortens making body parts move






15. Process that results in cell division to produce gametes






16. Epidermis - vascular - ground






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






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






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






20. xylem and phloem; transport fluid and nutrients internally






21. Produce progesterone and estrogens - in addition to eggs






22. 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






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






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






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






26. Produces and stores nutrients through photosynthesis






27. Organelle containing genetic material






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






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






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






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






32. Organelle containing enzymes used in cell digestion






33. Discovered mitosis






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






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






36. Process that results in cell division






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






38. Plant with specialized tissue for conducting water and nutrients






39. Any cell in a multicellular organism except the gametes






40. Largest organ in terms of surface area






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






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






43. The basic structural and functional unit of all organisms






44. Produce testosterone and sperm






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






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






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






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






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






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