Detailed explanation-1: -Cell membranes enable organisms to maintain homeostasis by regulating the materials that may enter or leave a cell. Some materials easily cross the cell membrane without the input of energy; other materials require energy input in order to cross through the cell membrane.

Detailed explanation-2: -The main organelle responsible for maintaining homeostasis is the cell membrane. Why is the cell membrane so important for maintaining homeostasis? The cell membrane, also known as the plasma membrane, plays an important role in homeostasis via the regulation of the passage of materials into and out of the cell.

Detailed explanation-3: -All cells have a cell membrane. This membrane controls what goes into and out of the cells. Some substances, such as gases and water, can pass across the membrane easily by diffusion.

Detailed explanation-4: -Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization.

Detailed explanation-5: -Answer and Explanation: Organelles work together to maintain homeostasis by each performing different jobs that keep the cell alive. This division of labor helps keep the cell in balance, and different organelles rely on each other for their products. For example, the mitochondria make energy.
