Question

1. why do cells need to maintain homeostasis?

diffusion molecules are always moving. as they move, they bump into one another. crowded, or concentrated, molecules collide more often. collisions cause molecules to push away from one another. over time, as molecules continue colliding and moving apart, they spread evenly throughout the space and become less concentrated. diffusion (dih fyoo zhun) is the process by which molecules move from an area of higher concentration to an area of lower concentration. consider a cell in the lining of your lungs. the cell is in contact with the air that you breathe. the air outside the cell has a higher concentration of oxygen. what happens? oxygen moves easily into the cell. the diffusion of oxygen into the cell does not require the cell to use any of its energy. diffusion is a form of passive transport. figure 3 shows how insects use spiracles instead of lungs to diffuse oxygen into their cells.

Explanation:

Cells need homeostasis to survive. Homeostasis maintains stable internal conditions (like pH, temperature, solute concentrations) for vital processes. For example, diffusion (passive transport) of oxygen (as in lung cells) relies on concentration gradients, which homeostasis helps sustain. Enzymes, crucial for metabolism, work best in specific conditions maintained by homeostasis. Without it, cell functions (e.g., respiration, protein synthesis) fail, leading to cell death.

Answer:

Cells need to maintain homeostasis to sustain stable internal conditions (e.g., solute concentrations, pH, temperature) required for vital processes like metabolism (enzymes function optimally in specific conditions), nutrient uptake (e.g., oxygen diffusion), and waste removal. Without homeostasis, cell functions fail, leading to cell death.
