  12. 33. movement of materials against a concentration difference using energy
  13. 35. control system of the cell, contains DNA
  14. 37. eukaryotes living as unicellular organisms
  15. 39. a specific protein whose shape fits that of a specific molecular messenger, such as a hormone; respond and bind to chemical signals
  16. 40. acidic, digestive enzyme that breaks down dead cells

  20. 47. organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell
  21. 48. active transport that occurs when the cell membrane forms a pocket around a particle --> pocket breaks away from membrane (vesicle) --> vesicle carries particle where it needs to go
  22. 49. pressure that must be applied to prevent osmotic movement across a semi permeable membrane
  23. 50. relatively constant internal physical and chemical conditions that organisms maintain
Down
  1. 1. less solutes in the cell

  10. 12. when the concentration of two solutions is the same
  11. 14. organism whose cell contains a nucleus
  12. 15. active transport where channels in lipid bilayer take in a substance on one side and push it out on the other
