Detailed explanation-1: -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-2: -One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.

Detailed explanation-3: -The cellular organelle/part present in all cells and helps maintain homeostasis are Endoplasmic reticulum (organelle) and plasma membrane (cellular part). They both effectively keep the homeostatic rate of the cell constant via osmosis and thus play a vital role in controlling cellular activities.

Detailed explanation-4: -Cellular and organismal homeostasis Homeostasis in an organism or colony of single celled organisms is regulated by secreted proteins and small molecules often functioning as signals. Homeostasis in the cell is maintained by regulation and by the exchange of materials and energy with its surroundings.
