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






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






3. Include macrophages - B- cells - and T- cells






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






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






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






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






8. Useful for tearing and scratching






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






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






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






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






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






14. 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






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






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






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






18. Stores solid waste products






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






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






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






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






23. Produces and stores nutrients through photosynthesis






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






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






26. Attaches to bones and is responsible for voluntary movements






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






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






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






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






31. Organelle in which calcium levels are regulated






32. Organelle in which proteins are synthesized






33. 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






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






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






36. Stores and releases bile






37. Holds tissues together






38. Process that results in cell division






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






40. Cells that form the outer surface of plants






41. Epidermis - vascular - ground






42. Organelle composed of microtubules within the nucleus that helps ensure that duplicated chromosomes are evenly distributed to the daughter cells






43. Protects the body and holds in heat






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






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






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






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






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






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






50. 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.
