Rough Endoplasmic Reticulum 28

Movement of particles from high to low concentration, e. g. , O 2 and CO 2 into and out of cells, respectively 29

Diffusion 30

Movement of water from high to low concentration; maintenance of osmotic pressure 31

Osmosis 32

Using pressure to push something through a cell membrane; removal of metabolic wastes 33

Filtration 34

35

Using a special protein carrier to move something from high to low concentration; e. g. , glucose entry 36

Facilitated Diffusion 37

Maintenance of a constant environment in a cell is called cellular _______ 38

Homeostasis 39

General term for bringing a substance into a cell that is too large to enter any other way 40

Endocytosis 41

Movement across a cell; endocytosis followed by exocytosis; e. g. , absorption of substances 42

Transcytosis 43

Expelling a substance from the cell into the extracellular fluid; exporting proteins 44

Exocytosis 45

Specific term to describe a cell’s engulfing solid particles; “celleating” 46

Phagocytosis 47

A type of active transport in which large molecules are taken into a cell in vesicles formed from coated pits in the cell membrane 48

Receptor-mediated Endocytosis 49

The constant movement of molecules with no net change in concentration 50

Brownian motion 51

A solution in which the concentration of dissolved substances is less than that of another solution 52

Hypotonic 53

A solution in which the concentration of dissolved substances is equal to that of another solution 54

Isotonic 55

The shrinking of cytoplasm by osmosis; e. g. , placing a cell in a hypertonic environment 56

Plasmolysis 57

58

Word used to describe what happens when an animal cell is placed in a hypotonic solution 59

Cytolysis 60

Interphase is divided into three separate phases. These are _______. 61

G 1, S, and G 2 62

During this phase of mitosis, chromosomes line up in the middle of the cell and spindle fibers attach to kinetochores 63

Metaphase 64

During this phase of mitosis, the cleavage furrow forms between daughter cells; nuclear envelope and nucleolus reappear 65

Telophase 66

The cell cycle consists of Interphase, Mitosis, and ______. 67

Cytokinesis 68

____ cells are committed to a specific cell line, I. e. , epithelial, connective, muscle, or nervous 69
