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. Division of the cytoplasm during cell division






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






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






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






5. Contracts or shortens making body parts move






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






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






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






9. Largest organ in terms of surface area






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






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






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






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






14. Organelle containing enzymes used in cell digestion






15. Release of water from plants through stomata






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






17. Process that results in cell division to produce gametes






18. Produces and stores nutrients through photosynthesis






19. 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






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






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






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






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






24. 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






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






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






27. 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






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






29. Attaches to bones and is responsible for voluntary movements






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






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






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






33. 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






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






35. Process that results in cell division






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






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






38. Epidermis - vascular - ground






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






40. Discovered mitosis






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






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






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






44. Obsolete taxonomic group containing bacteria and cyanobacteria






45. 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






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






47. Stores solid waste products






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






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






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