Coral reefs are unique, living structures. Even though they appear to be hard, rock-like structures, the soft-bodied coral animals that build the elaborate, hard, rock-like reef structures around themselves live inside. Corals are unique animals because they have photosynthetic algae that live inside their cells. This unique relationship is beneficial to the algae since it has a safe place to live inside the coral cells, and it is beneficial to the coral since the algae are producing food via photosynthesis. From the description above, what type of symbiosis is described, and at what ecological level does this relationship exist? The relationship is an example of parasitism, and it exists at the community level. The relationship is an example of mutualism, and it exists at the community level. The relationship is an example of commensalism, and it exists at the community level. The relationship is an example of mutualism, and it exists at the ecosystem level.
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.
