Like other living organisms, cells must use homeostasis to keep everything in balance in order to stay alive. Homeostasis is a set of internal conditions maintained by living things despite a changing environment, Homeostasis allows organisms to function best. All cells must maintain homeostasis to stay alive.
Homeostasis is important for cells because it allows them to stay in balance. If cells are out of balance, they will not be able to carry out the chemical reactions they need to survive.For example. In homeostasis an equal amount of water flows into the cell and out of the cell. The cell maintains its shape and has enough water to carry out chemical reactions. However, if the environment has more water than the cell, the cell will be out of homeostasis. Water will rush into the cell and animal cells can even burst from this. Homeostasis is also important for concentrations of salts and sugar as well as pH.
The main organelle responsible for maintaining homeostasis is the cell membrane. The cell membrane plays an important role in homeostasis by regulating the movement of materials into and out of the cell. The structure of the cell membrane allows certain materials to pass in and out of the cell.
This goes with the Science Standard ,
S7L2. Obtain, evaluate, and communicate information to describe how cell structures, cells,
tissues, organs, and organ systems interact to maintain the basic needs of organisms.
a. Develop a model and construct an explanation of how cell structures (specifically the
nucleus, cytoplasm, cell membrane, cell wall, chloroplasts, lysosome, and mitochondria)
contribute to the function of the cell as a system in obtaining nutrients in order to grow,
reproduce, make needed materials, and process waste.
