Why are folded membranes an advantage to a cell?
Answer (2)
Folded membranes increase a cell's surface area for nutrient absorption and transport, while fluidity allows for greater flexibility and motion of membrane components essential for transport mechanisms. These features contribute to a cell's ability to regulate substances entering or exiting the cell and adapt to different environmental conditions.
Folded membranes are an advantage to a cell because they increase the surface area available for absorption and transport of nutrients. Membrane folds, such as microvilli, allow the cell to absorb more substances efficiently. Additionally, the fluidity of the cell membrane is crucial as it contributes to the flexibility of the cell, enabling the motion of membrane components that is essential for various types of membrane transport mechanisms.
There are many advantages to having a fluid cell membrane. For one, it allows the membrane to be selectively permeable, wherein it can regulate the entry and exit of substances. The presence of different types of proteins in the plasma membrane aids in the active and passive transport of materials, which is vital for the cell's survival. The flexibility provided by fluidity also means cells can adapt their shape and size when ingesting substances, similar to cells with ruffled membranes that can engulf larger particles, giving them an evolutionary edge in certain conditions.
Folded membranes enhance a cell's functionality by increasing surface area for nutrient absorption, providing flexibility for transport, and allowing selective permeability to regulate substance movement. This adaptability is crucial for cellular health and survival. Overall, they contribute to a cell's ability to respond effectively to its environment.
