An organism’s ability to maintain steady internal conditions when outside conditions change, also called maintaining balance.

• Homeostasis

• Hormones

• Hydrotropism

• Homer

In plant cells, the force, exerted by the flow of water, within the cell that pushes the plasma membrane against the cell wall. This force gives plants structure and helps them stand up and not wilt.
