Bilayer of phospholipids with proteins dispersed throughout

Cell (plasma) membrane

Membranous network studded with ribosomes; protein synthesis

Rough Endoplasmic Reticulum

Kidney shaped organelle whose inner membrane (cristae) is the site of cellular respiration; “powerhouse”

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
