specialized integral membrane proteins, often called "water channels," that facilitate the rapid transport of water molecules across cell membranes in response to osmotic gradients.

the passive, net movement of molecules or ions from an area of higher concentration to an area of lower concentration, down a concentration gradient

Facilitated Diffusion

type of passive transport where molecules move across a cell membrane down their concentration gradient (high to low) through specialized transmembrane proteins

the self-regulating process by which biological systems maintain internal stability while adjusting to changing external conditions

a solution with a higher solute concentration compared to another solution, typically the interior of a cell

a solution with a lower concentration of solutes (like salt or sugar) compared to the cytosol inside a cell

a solution that has the same concentration of solutes (like salt or sugar) as another solution, typically the cytoplasm inside a cell, across a semipermeable membrane

a specialized, functional unit composed of different tissues that work together to perform specific tasks, representing a hierarchical level between tissues and organ systems

a specialized, functional group of organs and tissues in multicellular organisms that work together to perform complex physiological tasks necessary for life

the passive, spontaneous movement of water molecules across a semipermeable membrane from a region of lower solute concentration (hypotonic) to a region of higher solute concentration (hypertonic)

the minimum pressure required to stop the net movement of water (solvent) across a semipermeable membrane into a more concentrated solution.

a protein molecule located on the surface of a cell, in the cytoplasm, or in the nucleus that binds to specific molecules (ligands)—such as hormones, neurotransmitters, or antigens

a group of similar cells and their intercellular material, derived from the same origin, that work together to perform a specific function within a multicellular organism

Term	Definition
Aquaporin	specialized integral membrane proteins, often called "water channels," that facilitate the rapid transport of water molecules across cell membranes in response to osmotic gradients.
Diffusion	the passive, net movement of molecules or ions from an area of higher concentration to an area of lower concentration, down a concentration gradient
Facilitated Diffusion	type of passive transport where molecules move across a cell membrane down their concentration gradient (high to low) through specialized transmembrane proteins
Homeostasis	the self-regulating process by which biological systems maintain internal stability while adjusting to changing external conditions
Hypertonic	a solution with a higher solute concentration compared to another solution, typically the interior of a cell
Hypotonic	a solution with a lower concentration of solutes (like salt or sugar) compared to the cytosol inside a cell
Isotonic	a solution that has the same concentration of solutes (like salt or sugar) as another solution, typically the cytoplasm inside a cell, across a semipermeable membrane
Organ	a specialized, functional unit composed of different tissues that work together to perform specific tasks, representing a hierarchical level between tissues and organ systems
Organ System	a specialized, functional group of organs and tissues in multicellular organisms that work together to perform complex physiological tasks necessary for life
Osmosis	the passive, spontaneous movement of water molecules across a semipermeable membrane from a region of lower solute concentration (hypotonic) to a region of higher solute concentration (hypertonic)
Osmotic Pressure	the minimum pressure required to stop the net movement of water (solvent) across a semipermeable membrane into a more concentrated solution.
Receptor	a protein molecule located on the surface of a cell, in the cytoplasm, or in the nucleus that binds to specific molecules (ligands)—such as hormones, neurotransmitters, or antigens
Tissue	a group of similar cells and their intercellular material, derived from the same origin, that work together to perform a specific function within a multicellular organism
