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. xylem and phloem; transport fluid and nutrients internally






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






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






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






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






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






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






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






9. Attaches to bones and is responsible for voluntary movements






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






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






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






13. The process by which a cell becomes specialized for a specific structure or function






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






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






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






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






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






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






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






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






22. Obsolete taxonomic group containing bacteria and cyanobacteria






23. Organelle in which calcium levels are regulated






24. Organelle containing genetic material






25. Connective - muscle - nervous - epithelial






26. Organelle containing enzymes used in cell digestion






27. Plant with specialized tissue for conducting water and nutrients






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






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






31. 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






32. Division of the cytoplasm during cell division






33. Produces and stores nutrients through photosynthesis






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






35. Produce testosterone and sperm






36. Stores solid waste products






37. Epidermis - vascular - ground






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






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






40. 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






41. 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.






42. Holds tissues together






43. Discovered mitosis






44. Release of water from plants through stomata






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






46. Protects the body and holds in heat






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






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






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






50. Sweat glands and sebaceous glands
