Why is a large surface area : volume ratio needed for cells to function properly?

a.Adequate surface area (plasma membrane) is needed to furnish nutrients to and expel wastes from the volume (cytoplasm).
b. Smaller volumes reduce and larger surface areas reduce the cell's ability to bring nutrients in and get rid of waste.
c. A smaller surface area allows the cell to increase its metabolic activity by bringing in even more nutrients than larger surface areas. d. The surface area and volume increase at the rate to ensure cell growth and reproduction.

A large surface area to volume ratio is needed for cells to function properly because it allows for efficient exchange of materials between the cell and its environment. A larger surface area allows for more efficient transport of nutrients and waste products, as well as more efficient communication between cells. Additionally, a larger surface area allows for more efficient absorption of energy from the environment, which is necessary for the cell to carry out its metabolic processes.

The correct answer is a. Adequate surface area (plasma membrane) is needed to furnish nutrients to and expel wastes from the volume (cytoplasm).

To understand why a large surface area to volume ratio is needed for cells to function properly, we need to consider the basic functions of a cell. Cells require nutrients to carry out their metabolic processes and produce energy, while also generating waste that needs to be expelled. The surface area of a cell allows for the exchange of substances with the environment, while the volume contains the organelles and structures necessary for cell functions.

If a cell has a small surface area and a large volume, it would struggle to efficiently exchange nutrients and waste with its surroundings. The limited surface area would restrict the amount of nutrients that can enter the cell and the waste that can be expelled. This could lead to a buildup of waste products and a deficiency of essential nutrients, potentially disrupting the cell's functions.

On the other hand, if a cell has a large surface area and a small volume, it would have a higher capacity to exchange substances. The increased surface area would allow for a greater contact area with the environment, facilitating the uptake of nutrients and the removal of waste. This would enable the cell to adequately support its metabolic processes and maintain homeostasis.

In summary, a large surface area to volume ratio is essential for cells to function properly because it enables efficient exchange of substances, ensuring a sufficient supply of nutrients and removal of waste.

A. Adequate surface area (plasma membrane) is needed to furnish nutrients to and expel wastes from the volume (cytoplasm).
