3.1 Vocabulary Review Homeostasis

The movement of molecules across a cell membrane against their concentration gradient, requiring energy (usually in the form of ATP)

• active transport

• passive transport

• diffusion

• osmosis

The process by which molecules spread from areas of high concentration to areas of low concentration until evenly distributed.

• active transport

• passive transport

• diffusion

• osmosis

The ability of a system to maintain its state and resist changes despite external influences.

• stability

• balance

• plasma membrane

• regulation

NGSS.HS-LS1-3

The thin, flexible barrier surrounding a cell, composed of a lipid bilayer that controls what enters and exits the cell.

• regulation

The mechanisms that organisms use to control internal processes and maintain homeostasis.

NGSS.HS-LS1-3

A process in which the output of a system influences its own operation, often to maintain homeostasis.

• feedback mechanism

• feedback loop

• pump

• homeostasis

NGSS.HS-LS1-3

The process by which living organisms maintain a stable internal environment (like temperature and pH) despite changes in the external environment.

• feedback mechanism

NGSS.HS-LS1-3

A mechanism that moves substances across a membrane against their concentration gradient, often requiring energy, such as in active transport.

• feedback mechanism

• feedback loop

• pump

• homeostasis

A cycle of events where a change in a system causes further changes, which can be either positive (enhancing the change) or negative (reducing the change).

• feedback mechanism

• feedback loop

• pump

• homeostasis
