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. Plant with specialized tissue for conducting water and nutrients






2. Useful for tearing and scratching






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






4. Produces hormones directly into the blood; pituitary gland - thyroid gland - adrenal glands - pancreas - ovaries - testes - thymus gland






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






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






7. Largest organ in terms of surface area






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






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






10. Process that results in cell division to produce gametes






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






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






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






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






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






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






17. 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






18. Produces digestive enzymes and the hormones insulin and glucagons






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






20. 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






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






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






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






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






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






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






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






28. The basic structural and functional unit of all organisms






29. Any cell in a multicellular organism except the gametes






30. Discovered meiosis






31. Release of water from plants through stomata






32. Discovered mitosis






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






34. Protects the body and holds in heat






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






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






37. Holds tissues together






38. Connective - muscle - nervous - epithelial






39. 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






40. Organelle in which calcium levels are regulated






41. Brain and spinal cord






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






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






44. Third phase of mitosis and of meiosis I and II - in which the sister chromatids separate and move toward the poles of the spindle






45. xylem and phloem; transport fluid and nutrients internally






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






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






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






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






50. Cells that form the outer surface of plants
