The cell membrane is essential for a cell to maintain balance which we call

Homeostasis

Explanation:

Cell membrane (plasma membrane) is known to be a semi-permeable membrane that regulates the movement of substances in and out of the cell. Similarly, it is a phospholipid bilayer that separates the outer (external) environment from the inner cellular environment. Thus, plasma membrane maintains homeostasis by regulating the movement of materials or cell contents that can pass in or out of the cell on order to main balance equilibrium.

Classification systems change over time because Scientists find new evidence in their studies. The development of science led to discoveries that made the classification can change or increase

Further explanation

The classification system always develops according to the development of science. classification systems can vary according to experts who present them and can experience changes along with the latest findings

Initially living things were classified into two, namely Plantae (plants) and Animalia (animals)

At that time the fungus was inserted into the plant, but as it developed, it was known that the fungus was not chlorophyll and its cell wall from chitin so that it was different from plant cells consisting of cellulose so that the fungus was separated into its kingdom, becoming Fungi

Single-celled living creatures that did not have a core membrane were then classified as kingdom Monera

Then the protozoa and algae are differentiated and removed from the kingdom Monera into the kingdom Protista

Eventually, Kingdom Monera was used and instead the kingdom of Archaebacteria and Eubacteria appeared. So it appeared into 6 kingdoms, namely:

1. Animalia (animal), are multicellular \ 2. Plantae (plants) are multicellular 3. Fungi have eukaryotic cells 4. Protists, single-celled 5. Archaebacteria 6. and Eubacteria

So the classification systems change over time because the Scientists find new evidence in their studies
