idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells

Over 200 different types of human cells. Types differ in size, shape, subcellular components, and functions

The membrane at the boundary of every cell that acts as a selective barrier, thereby regulating the cell's chemical composition

A jellylike fluid inside the cell in which the organelles are suspended

Control center of the cell

like tiny organs within cells.

A selectively-permeable phospholipid bilayer forming the boundary of the cells

mechanical barrier, selective permeability, electrochemical gradient, communication, cell signaling

fluid within cells

fluid outside the cell

A molecule that is a constituent of the inner bilayer of biological membranes, having a polar, hydrophilic head and a nonpolar, hydrophobic tail.

A lipid that forms an essential component of animal cell membranes and acts as a precursor molecule for the synthesis of other biologically important steroids.

water loving portion of the lipid bilayer in cells

Water fearing portion of the bilayer

Proteins that penetrate the hydrophobic interior of the lipid bilayer

Which are types of transmembrane proteins

a protein that allows the transport of specific substances across a cell membrane. usually is assisted by water

Proteins that bind solutes and transport them across the plasma membrane

The proteins of a membrane that are not embedded in the lipid bilayer; they are appendages loosely bound to the surface of the membrane.

Anchoring junctions that prevent cells from being pulled apart

Movement of molecules from an area of higher concentration to an area of lower concentration.

membrane that allows some substances to pass more easily than others and blocks the passage of some substances altogether

Diffusion that doesn't involve a direct input of energy or assistance by carrier proteins.

Movement of specific molecules across cell membranes through protein channels or protein carriers

Diffusion of water through a selectively permeable membrane

The ability of a solution surrounding a cell to cause that cell to gain or lose water.

A solution with the same concentration of water and solutes as inside a cell, resulting in the cell retaining its normal shape because there is no net movement of water.

Solute concentration is greater than that inside the cell; cell loses water and will shrink

the concentration of dissolved substances is lower in the solution outside the cell than the concentration inside the cell. the cell will burst

Energy-requiring process that moves material across a cell membrane against a concentration gradient

move solutes "uphill" against a concentration gradient expending ATP

this is an example of going against the concentration gradient

Which is an example of going with the concentration gradient

a carrier protein that uses ATP to actively transport sodium ions out of a cell and potassium ions into the cell

Transport of large particles and macromolecules across plasma membranes

moving substances into, across, and then out of a cell

an energy transfer molecule similar to ATP that releases free energy with the hydrolysis of its terminal phosphate group

(adenosine triphosphate) main energy source that cells use for most of their work

process by which a cell takes material into the cell by infolding of the cell membrane

A type of endocytosis in which a cell engulfs large particles or whole cells

A type of endocytosis in which the cell ingests extracellular fluid and its dissolved solutes.

The uptake of specific molecules based on a cell's receptor proteins

a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.
