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. Contracts or shortens making body parts move






2. The basic structural and functional unit of all organisms






3. Process that results in cell division






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






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






6. Stores and releases bile






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






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






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






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






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






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






13. Obsolete taxonomic group containing bacteria and cyanobacteria






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






15. Cells that form the outer surface of plants






16. Release of water from plants through stomata






17. Process that results in cell division to produce gametes






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






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






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






21. Discovered mitosis






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






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






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






25. Discovered meiosis






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






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






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






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






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






31. Produce progesterone and estrogens - in addition to eggs






32. Brain and spinal cord






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






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






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






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






37. Epidermis - vascular - ground






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






39. Plant with specialized tissue for conducting water and nutrients






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






41. 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.






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






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






44. Protects the body and holds in heat






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






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






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






48. Organelle containing enzymes used in cell digestion






49. Division of the cytoplasm during cell division






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