What process requires some of the cell's energy and includes endocytosis and exocytosis?
What is the membrane that surrounds the contents of a cell and allows only certain things into and out of the cell?
What is a way of describing the structure and function of a cell membrane; includes the phospholipid bilayer, proteins, carbohydrates, and cholesterol?
What is the process of keeping the internal conditions of an organism stable?
What is attracted to water or able to dissolve in water; water-loving?
What is having a partial positive electrical charge on one end and a partial negative charge on the other end?
What is the two layers of phospholipid molecules arranged tail to tail that help to make up cell membranes?
What is the process that does not require energy from the cell and includes osmosis and diffusion?
What is repelled by water or not able to be dissolved in water; water-fearing?
What is the movement of materials into and out of cells?
What is a property of cell membranes that allows only certain things to cross but not others>?
What is a difference in the concentration of ions or other dissolved particles between two regions?
What is the movement of molecules from an area of higher concentration to an area of lower concentration?
What is the state of having equal concentrations as molecules move into and out of a cell at the same time?
What is the diffusion of molecules across a membrane through special proteins in the membrane?
What are proteins present in the cell membrane that allow different types of substances to pass through the membrane?
Having a higher solute concentration in the solution outside the cell than inside the cell, causing the cell to shrink
Having a lower solute concentration in the solution outside the cell than inside the cell, causing the cell to swell
Having equal solute concentrations inside and outside the cell
The movement of water across a semi-permeable membrane
The pressure at which osmosis stops
Dissolved particles in a solution
The pressure created by osmosis as water enters into a plant cell
Plant cell loses water and its plasma membrane pulls away from the cell wall occurring in a hypertonic solution due to osmosis
A process that requires energy to move a substance from an area of lower concentration to an area of higher concentration
Process used by a cell to take in a large particle
Process used by a cell to release materials out of the cell
A protein present in the cell membrane that helps to move materials into and out of the cell
