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. 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.






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






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






4. Division of the cytoplasm during cell division






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






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






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






8. Brain and spinal cord






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






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






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






12. Stores solid waste products






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






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






15. Connective - muscle - nervous - epithelial






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






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






18. Responsible for the breakdown and absorption of food and the removal of solid waste; include the alimentary canal (mouth - esophagus - stomach - small intestine - large intestine - colon/ rectum) and the accessory organs (liver - pancreas - gall blad






19. Release of water from plants through stomata






20. Produces and stores nutrients through photosynthesis






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






22. Discovered mitosis






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






24. 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.






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






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






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






28. Organelle containing genetic material






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






30. Useful for tearing and scratching






31. Produce progesterone and estrogens - in addition to eggs






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






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






34. Process that results in cell division to produce gametes






35. Plant with specialized tissue for conducting water and nutrients






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






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






38. Last stage of mitosis - in which the cell membrane begins to pinch the cell in two - cytokinesis begins - and the nuclear membrane forms around the chromosomes






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






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






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






42. Produces digestive enzymes and the hormones insulin and glucagons






43. Discovered meiosis






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






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






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






47. 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






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






49. Process that results in cell division






50. Largest organ in terms of surface area
