Make a T-chart using the following paragraph: All living organisms will fit into two different categories; prokaryotes and eukaryotes. Eukaryotes, the more complex cells, are made up of one or many cells. These eukaryotic cells have a nucleus and membrane-bound organelles. Prokaryotes, the simpler cells, do not have a nucleus or membrane-bound organelles. Almost all the prokaryote organisms are single-celled. It is important to know that the only way we can see these organisms is by using a microscope.
Structure and Composition of Cell Membrane
Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasma membrane,' separates the inner content from its exterior environment.
Cell Membrane
The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for cell membrane was given by J. Plowe. The cell membrane separates the cell's internal environment from the extracellular space. This separation allows the protection of cells from their environment.
Prokaryotes vs Eukaryotes
The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.
