Rough Endoplasmic Reticulum
Movement of particles from high to low concentration, e. g Movement of particles from high to low concentration, e.g., O2 and CO2 into and out of cells, respectively
Diffusion
Movement of water from high to low concentration; maintenance of osmotic pressure
Osmosis
Using pressure to push something through a cell membrane; removal of metabolic wastes
Filtration
Daily Double!!
Using a special protein carrier to move something from high to low concentration; e.g., glucose entry
Facilitated Diffusion
Maintenance of a constant environment in a cell is called cellular ______________
Homeostasis
General term for bringing a substance into a cell that is too large to enter any other way
Endocytosis
Movement across a cell; endocytosis followed by exocytosis; e. g Movement across a cell; endocytosis followed by exocytosis; e.g., absorption of substances
Transcytosis
Expelling a substance from the cell into the extracellular fluid; exporting proteins
Exocytosis
Specific term to describe a cell’s engulfing solid particles; “cell-eating”
Phagocytosis
A type of active transport in which large molecules are taken into a cell in vesicles formed from coated pits in the cell membrane
Receptor-mediated Endocytosis
The constant movement of molecules with no net change in concentration
Brownian motion
A solution in which the concentration of dissolved substances is less than that of another solution
Hypotonic
A solution in which the concentration of dissolved substances is equal to that of another solution
Isotonic
The shrinking of cytoplasm by osmosis; e. g The shrinking of cytoplasm by osmosis; e.g., placing a cell in a hypertonic environment
Plasmolysis
Daily Double!!
Word used to describe what happens when an animal cell is placed in a hypotonic solution
Cytolysis
Interphase is divided into three separate phases. These are _______.
G1, S, and G2
During this phase of mitosis, chromosomes line up in the middle of the cell and spindle fibers attach to kinetochores
Metaphase
During this phase of mitosis, the cleavage furrow forms between daughter cells; nuclear envelope and nucleolus reappear
Telophase
The cell cycle consists of Interphase, Mitosis, and ____________.
Cytokinesis
________ cells are committed to a specific cell line, I. e ________ cells are committed to a specific cell line, I.e., epithelial, connective, muscle, or nervous
Progenitor cells
