Living cells maintain homoeostasis by controlling materials that enter and leave the cell. This is made possible through the permeable cell membrane which is selective on the substances that pass through it.
The cell membrane acts as a "goalie" for a plant cell, controlling what substances can enter and exit the cell to maintain internal balance.
The cell membrane, specifically through the process of selective permeability, helps to maintain a chemical balance within a cell by controlling the substances that can enter and exit the cell. This regulation ensures that essential molecules are able to enter the cell while harmful substances are kept out, contributing to the overall health and function of the cell.
The cell membrane functions as a barrier to protect the cell's internal environment, but it also needs to allow essential nutrients and molecules to enter the cell for survival. Likewise, waste and other materials need to be able to leave the cell to maintain proper cellular function and prevent buildup of harmful substances. This balance of permeability is crucial for the cell's overall health and function.
Materials can enter a cell through processes like diffusion, facilitated diffusion, and active transport. These substances can leave a cell through processes such as diffusion, osmosis, and exocytosis.
The cell membrane holds both plant and animal cells together. It acts as a barrier, controlling the substances that enter and exit the cell to maintain internal balance. Additionally, in plant cells, the cell wall provides structural support and helps maintain shape.
gradients are an example. Electric gradients are controlled by the transport of Na+ and K+ and H+, etc.
The Plasma Membrane
Materials must enter and leave the cell in order to maintain a healthy internal environment and carry out cellular processes. Nutrients and oxygen need to enter the cell to provide energy and support growth, while waste products and byproducts of cellular activities must leave the cell to prevent toxicity and maintain homeostasis.

Materials usually enter through the cell wall.
The cell membrane of a plant cell allows certain materials to enter and exit through processes like diffusion, osmosis, and active transport. These processes help maintain the balance of nutrients and waste products within the cell.

Lysosomes are cell organelles that contain hydrolase enzyme that break down any waste materials or foreign materials that enter a living cell. So it is important to protect the cell from foreign elements including microorganisms like virus, bacteria, protozoa, fungi, etc. that could cause diseases in the living body and kill cells.
