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






2. Sweat glands and sebaceous glands






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






4. Largest organ in terms of surface area






5. 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.






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






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






8. Produces digestive enzymes and the hormones insulin and glucagons






9. Organelle containing genetic material






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






11. 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






12. Process that results in cell division to produce gametes






13. xylem and phloem; transport fluid and nutrients internally






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






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






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






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






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






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






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






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






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






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






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






25. Nutrient conducting plant tissue; formed like small tubules; living cells






26. Produce progesterone and estrogens - in addition to eggs






27. Brain and spinal cord






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






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






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






31. Your first line of defense against disease and helps regulate body temperature; skin - glands - hair - nails






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






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






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






35. 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






36. Contracts or shortens making body parts move






37. Produces and stores nutrients through photosynthesis






38. Epidermis - vascular - ground






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






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






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






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






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






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






45. Cells that form the outer surface of plants






46. Any cell in a multicellular organism except the gametes






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






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






49. Division of the cytoplasm during cell division






50. Plant with specialized tissue for conducting water and nutrients
