  1. describes a solution whose solute concentration is higher than the solute concentration inside the cell
    Hypertonic
  2. describes a solution whose solute concentration is lower than the solute concentration inside the cell
    Hypotonic
  3. a solution whose solute concentration is equal to the solute concentration inside the cell
    Isotonic
  4. the diffusion of water or another solvent from a more dilute solution to a more concentrated solution through a membrane that is permeable to the solvent
    Osmosis
  5. the transport of substances through a cell membrane along a concentration gradient with aid of carrier proteins
    Facilitated Diffusion
  6. the movement of chemical substances usually across the cell membrane, against a concentration gradient; requires cell to use energy
    Active Transport
  7. the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell
    Endocytosis
  8. process in which extensions of cytoplasm surrounded and engulf large particles and take them into the cell
    Phagocytosis
  9. process by which a cell takes in liquid from the surrounding environment
    Pinocytosis
  10. the process by which a substance is released from the cell through a vesicle that transports the substance to the cell surface and then fuses with the membrane to let the substance out
    Exocytosis
  11. an organism that produces its own nutrients from inorganic substances or from the environment instead of consuming other organisms
    Autotrophs
  12. an organism that obtains organic food molecules by eating other organisms or their by-products and that cannot synthesize organic compounds form inorganic materials
    Heterotrophs
  13. particles of nucleic acids, proteins and in some cases lipids
    Virus
  14. a virus's protein coat
    Capsid
  15. viruses that infect bacteria
    Bacteriophage
  16. virus enters the cell, makes copies to itself and causes the cell to burst
    Lytic Infection
  17. host cell makes copies of the cell indefinitely; a virus integrates its DNA into the DNA of the host cell and the viral genetic information replicates along with the host cell's DNA
    Lysogenic Infection
  18. the viral DNA that is embedded in the host's DNA
    Prophage
  19. viruses that contain RNA as their genetic information
    Retrovirus
  20. single-stranded RNA molecules that have no surrounding capsid
    Viroids
  21. basic unit of all forms of life
    Cell
  22. the theory that states that all living things are made up of cells
    Cell Theory
  23. an organism that consists of a single cell that does not have a nucleus of cell organelles
    Prokaryote
  24. an organism made up of cells that have a nucleus enclosed by a membrane multiple chromosomes and mitotic cycle
    Eukaryote
  25. one of the small bodies found in the cytoplasm of a cell and specialized to preform a specific function
    Organelles
  26. the region of the cell within the membrane that includes the fluid, the cytoskeleton and all of the organelles except the nucleus
    Cytoplasm
  27. a cell organelle composed of RNA and protein; the sight of protein synthesis
    Ribosome
  28. in a eukaryotic cell, a membrane-bound organelle that contains the cells DNA and that has role in processes such as growth, metabolism and reproduction
    Nucleus
  29. a system of membranes that is found in a cell's cytoplasm and that assists in the production, processing and transport of proteins and in the production of lipids
    Endoplasmic Reticulum
  30. cell organelle that helps make and package materials to be transported out of the cell
    Golgi Bodies
  31. in eukaryotic cells, the cell organelle that is surrounded by two membranes and is the site for cellular respiration which produces ATP
    Mitochondrion
  32. on organelle found in plant and algae cells where photosynthesis occurs
    Chloroplast
  33. a large cavity or sac that is found in plant cells or protozoans and that contains air or partially digested food
    Vacuole
  34. a phospholipid layer hat covers a cell's surface and acts as a barrier between the inside of the cell and the cell's environment
    Cell Membrane
  35. a rigid structure that surrounds the cells membrane and provides support to the cell; mostly found in plant cells but sometime found in bacteria
    Cell Wall
  36. a cell organelle that contains digestive enzymes
    Lysosome
  37. a basic structure of a biological membrane; composed of two layers of phosopholipids
    Lipid Bilayer
  38. the mass of solute in a given volume of solution or mass/volume
    Concentration
  39. the movement of particles from regions of higher density to regions of lower density
    Diffusion
  40. in chemistry the state in which a chemical reaction and the reverse chemical reaction occur at the same rate such as the concentrations of reactions and products do not changeEquilibrium
    Equilibrium
