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: -Role of mitochondria in nutrient homeostasis The mitochondrion also earned the center stage. In addition to its traditional role as the cell’s power plant, this organelle engages in homeostatic processes such as nutrient sensing and lipid catabolism.

Detailed explanation-4: -Channel proteins and carrier proteins help substances diffuse across a cell membrane. In this diagram, the channel and carrier proteins are helping substances move into the cell (from the extracellular space to the intracellular space). The channel protein has an opening that allows the substances to cross.

Detailed explanation-5: -homeostasis because the membrane regulates all materials that enter or leave the cell.
