  1. Michigan High School Science Meap Test STUDY of LIFE Biology Review

  2. LC. Biology Cells Benchmark 2 Compare and contrast ways in which selected cells are specialized to carry out particular life functions.

  3. Cell membrane No true nucleus No membrane-bound cell organelles Cytoplasm Kingdom Monera--Bacteria Cell Membrane True nucleus Membrane-bound cell organelles Cytoplasm Kingdoms-- Animalia, Plantae, Protista, Fungi Prokaryotic and EukaryoticCell Types

  4. Animal Cell Nucleus Cell membrane Rough ER Smooth ER cytoplasm Golgi body mitochondria lysosome

  5. Plant Cell Cell wall Cell Membrane Chloroplast vacuole Mitochondria Nucleus Golgi Body

  6. Neuron Specialized Cells Cells in onion root Red Blood Cells http://www.biology.arizona.edu/cell_bio/activities/cell_cycle/cell_cycle.html http://www.extension.iastate.edu/nutrition/supplements/iron.php http://www.mhhe.com/socscience/intro/ibank/set1.htm

  7. Chloroplast

  8. PHOTOSYNTHESIS • Converting light energy into food • Exciting electrons in chlorophyll to reduce Carbon dioxide to glucose (sugar) • Using water to replace electrons in chlorophyll • Giving off oxygen as a waste product

  9. Cell Membrane http://library.thinkquest.org/C004535/cell_membranes.html

  10. Endocytosis Exocytosis Cellular Transport

  11. Insulin ProteinReceptor Cell Membrane

  12. Osmotic Pressure

  13. Key Concepts Classifications of organisms by cell type plant, animal, bacteria Selected specialized plant and animal cells red blood cells, white blood cells, muscle cells, nerve cells, root cells, leaf cells, stem cells; Cell parts used for classification Organelle, nucleus, cell wall, cell membrane; Specialized functions reproduction, photosynthesis, transport; Cell shape

  14. Tools: microscopes http://www.enchantedlearning.com/devices/microscope/label/labelanswers.shtml

  15. Real-world contexts Reproduction, growth, response, movement, etc. of animals and plants. Functions of bacteria.

  16. Bacteria http://www.resa.net/nasa/bacteria.htm http://www.hhs.gov/asphep/presentation/diagnosticestacio.html

  17. Studying a picture of a cell taken with • an electron microscope, you find that • the cell has no nucleus and no mitochondria, • but it does have a cell membrane and a cell wall. • You conclude that the cell is probably from a(n) • plant • b. prokaryote • c. now extinct organism • d. animal

  18. a. plant Incorrect: although plants do have cell walls, they also have a nucleus and mitochondria Return to the Question

  19. You Pass with Flying Colors b. prokaryote Correct: The most distinguishing feature of prokaryotes is their lack of a nucleus and membrane bound organelles including mitochondria (and also endoplasmic reticulum, Golgi Apparatus, chloroplasts, vacuoles). The do have a cell wall. Return to the Question

  20. c. now extinct organism Incorrect: There is no way to tell this with the information given. Return to the Question

  21. d. Animal Incorrect: Animals do not have a cell wall and do have mitochondria and nuclei Return to the Question
