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. Chlorophyll containing plant cell organelle within which photosynthesis takes place






2. Connective - muscle - nervous - epithelial






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






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






5. 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.






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






7. Process that results in cell division to produce gametes






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






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






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






11. Organelle in which calcium levels are regulated






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






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






14. 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






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






16. Organelle containing enzymes used in cell digestion






17. Any cell in a multicellular organism except the gametes






18. Produces digestive enzymes and the hormones insulin and glucagons






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






20. Cells that form the outer surface of plants






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






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






23. The basic structural and functional unit of all organisms






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






25. Obsolete taxonomic group containing bacteria and cyanobacteria






26. 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






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






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. 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.






30. Stores solid waste products






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






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






33. 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






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






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






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






37. Produces and stores nutrients through photosynthesis






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






39. Contracts or shortens making body parts move






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






41. 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






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






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






44. Epidermis - vascular - ground






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






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






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






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






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






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