  1. an organ system is a group of organs that
    work together to perform a specific function
  2. which means of particle transport is shown in figure 7-5 above
    endocytosis
  3. which structure in the cell shown in figure 7-3 above modifies, sorts, and packages proteins and other materials for storage or release from the cell
    • structure A
    • (The Golgi Apparatus)
  4. equilibrium refers to
    movement of particles both into and out of the cell but no net gain of particles on either side
  5. which means of particles transport across the cell membrane does not require input of energy from the cell
    • none of the above require energy input from a cell
    • - diffusion, osmosis, facilitated diffusion
  6. which organelle converts the chemical energy stored in food such as glucose, into compounds that are more convenient for the cell to use immediate energy (i.e. ATP)
    mitochondrion
  7. the work of schleiden and Schwann can be summarized  by saying that
    all plants and animals are made of cells
  8. which of the following is a function of the cell membrane
    regulates the movement of materials into and out of the cell
  9. which of the following statements about the nucleus is NOT true
    the nucleus is the site of protein assembly
  10. which of the following enclose their DNA in a nucleus
    eukaryotes
  11. prokaryotes do contain
    • ribosomes, and DNA
    • (Both A and C)
  12. which of the following is an example of an organ
    heart
  13. the cell membrane that contains channels and pumps the help move materials from one side to the other. What are these channels and pumps made of
    proteins
  14. which sequence correctly traces the pat of a protein being produced within a cell
    ribosome, endoplasmic reticulum, golgi apparatus
  15. which of the following is NOT a principal of the cell theory
    very few cells are able to reproduce
  16. these cellular structures are membrane bound structures used to transport substances throughout the cell or to the cell membrane
    vessicles
  17. if an animal cell is hypotonic to its surrounding environment than osmosis would occur in this direction:
    water to move out of the cell
  18. these structures can be found in the cytoplasm, the nucleus or the endoplasmic reticulum:
    ribosomes
  19. if the concentration of oxygen inside of a cell (intracellular) equals the concentration of oxygen outside of the cell (extracellular) these two environments would be classified as being
    isotonic
  20. cell theory does NOT apply to
    rocks and soil
  21. which term describes the relatively constant internal physical conditions of an organism
    homeostasis
  22. looking at a cell under a microscope , you note that it is a prokaryote. How do you know?
    the cell lacks a nucleus
  23. the cell membrane is a bilayer composed primarily of this type of macromolecule
    lipids, in particular phospholipids
  24. a group of similar cells that perform a particular function is called
    a tissue
  25. which structure in the cell shown in figure 7-2 above stores materials, such as water, salts, proteins, and carbohydrates
    structure C (the vacuoles)
  26. during the process of osmosis, when the concentrations of solute molecules on both sides of a selectively permeable membrane are the same,the two solutions are said to be
    isotonic
  27. which list best represents the levels of organization in a multicellular organism from the simplest level to the most complex level
    cell, tissue, organ, organ system
  28. the major difference between the active transport processes of  "pinocytosis" and "phagocytosis"  is
    liquids is engulfed by pinocytosis whereas particles or clumps of particles are engulfed by phagocytosis
  29. which organelle contains enzymes that help break down other organelles and cell parts that are no longer useful to the cell and is considered "the garbage can" of the cell
    lysosomes
  30. who used a compound microscope to see chambers within cork and named them "cells"
    Robert Hooke
  31. which of the following organisms are prokaryotes
    bacteria (1-5 um)
  32. which of the following is NOT found in the nucleus
    mitochondria
  33. the primary function of the cell wall is to
    support and protect the cell
  34. which structure makes proteins using coded instructions that come from the nucleus
    ribosome
  35. which of the following is a function of the nucleus
    stores DNA
  36. the smooth endoplasmic reticulum produces these macromolecules/ organic compounds
    lipids and carbohydrates
  37. in general, cells with a higher concentration of sodium than its surrounding environment (tissue fluids or blood) would be classified osmotically as
    hypertonic
  38. a membrane bound cellular structure that is responsible for storing important materials or liquids for later use is called a
    vacuole
  39. these structures are responsible for both the organization of cell division, cell movement and the internal structure of the cell
    microfilaments and microtubules
  40. which means of particle transport is shown in Figure 7-4 above
    active transport
  41. which of the following is a function of the cytoskeleton
    helps a cell keep its shape
  42. the diffusion of water across a selectively permeable membrane is called
    osmosis
  43. which organelle would you expect to find in plant cells but not animal cells
    chloroplast
  44. the process by where cells become specialized in multicellular organisms is called

  45. the cell theory states that all things are made up of cells
    False; a living thing
