Process of maintaining a stable environment inside a cell or an entire organism.
a) Homeostasis
b) Concentration Gradient
c) Diffusion
d) Facilitated Diffusion

A measurement of how much the concentration of a substance changes across a distance.
a) Concentration Gradient
b) Passive Transport
c) Homeostasis
d) Osmosis

Substances cross the cell membrane without the cell providing energy.
a) Passive Transport
b) Active Transport
c) Transport Protein
d) Homeostasis

A substance moves through a membrane from an area of high concentration to an area of low concentration.
a) Diffusion
b) Passive Transport
c) Homeostasis
d) Biology

The diffusion of water molecules across a membrane.
a) Osmosis
b) Endocytosis
c) Exocytosis
d) Vesicle Transport

Diffusion with the help of transport proteins.
a) Facilitated Diffusion
b) Concentration Gradient
c) Homeostasis
d) Vesicle Transport

Special proteins in the membrane.
a) Transport Protein
b) Osmosis
c) Concentration Gradient
d) Homeostasis

A substance moves against the concentration gradient (uses energy from cells).
a) Active Transport
b) Concentration Gradient
c) Homeostasis
d) Sodium-Potassium Pump

When this pump is in operation, sodium ions are pumped out of the cell, and potassium ions are pumped into the cell. Both ions move from areas of lower to higher concentration.
a) Sodium-Potassium Pump
b) Passive Transport
c) Facilitated Diffusion
d) Concentration Gradient

Type of transport in which very large molecules cross the cell membrane.
a) Vesicle Transport
b) Sodium-Potassium Pump
c) Concentration Gradient
d) Homeostasis

Type of vesicle transport that moves a substance into the cell. The plasma membrane completely covers the substance, a vesicle pinches off from the membrane, and the vesicle carries the substance into the cell.
a) Endocytosis
b) Exocytosis
c) Concentration Gradient
d) Homeostasis

Type of vesicle transport that moves a substance out of the cell. A vesicle containing the substance moves through the cytoplasm to the cell membrane. Then, the vesicle membrane fuses with the cell membrane, and the substance is released outside the
a) Exocytosis
b) Endocytosis
c) Vesicle Transport
d) Active Transport
