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. Epidermis - vascular - ground






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






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






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






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






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






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






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






9. Process that results in cell division to produce gametes






10. 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.






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






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






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






14. Stores solid waste products






15. Holds tissues together






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






17. Release of water from plants through stomata






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






19. Obsolete taxonomic group containing bacteria and cyanobacteria






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






21. Protects the body and holds in heat






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






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






24. Region of condense chromosome that looks pinched; where spindle fibers attach during meiosis and mitosis.






25. Organelle that 'packages' proteins to be secreted from the cell






26. Organelle in which calcium levels are regulated






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






28. 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






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






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






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






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






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






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






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






36. Produces digestive enzymes and the hormones insulin and glucagons






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






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






39. Attaches to bones and is responsible for voluntary movements






40. Useful for tearing and scratching






41. Discovered meiosis






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






43. Largest organ in terms of surface area






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






45. Produce progesterone and estrogens - in addition to eggs






46. Stores and releases bile






47. Brain and spinal cord






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






49. Discovered mitosis






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