Study Notes

Cells maintain homeostasis to keep internal conditions stable despite changes in the environment, allowing them to function optimally.
Homeostasis involves maintaining a balance of water, salt, sugar concentrations, and pH levels within cells to support chemical reactions necessary for survival.
The cell membrane plays a crucial role in maintaining homeostasis by regulating the movement of materials into and out of the cell.
Osmosis is a passive transport process where water moves from high to low concentration to help cells maintain the right amount of water.
Active transport, facilitated by proteins in the cell membrane, helps maintain optimal levels of ions like potassium and sodium inside and outside the cell to support homeostasis.
