The surface area of the alveoli is where oxygen and carbon dioxide are exchanged across membranes. A large surface area enables a greater amount of gas transfer. The skin has two main functions: one is holding all our bits in one place and the other is to maintain body temerature. In the latter role, a large surface area is good for cooling the body but bad for keeping warm. So it is a compromise.
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
A cell's volume is the amount of material that can fit into the cell. A cell's surface area is the total amount of material that makes up the outside of the cell. The ratio of surface area to volume is the amount of surface area per unit volume of an object or collection of objects.

The inner membrane of mitochondria is highly folded into structures called cristae, which provide a large surface area for the electron transport chain and ATP synthase enzymes to generate energy through oxidative phosphorylation. This increased surface area allows for more efficient production of ATP molecules, the cell's primary energy source.
to provide a greater surface area in the organelle (increase surface area)
The endoplasmic reticulum (ER) has a lot of surface area due to its membrane structure, which folds and extends extensively throughout the cell. This large surface area allows for important cellular processes such as protein synthesis and lipid metabolism to occur efficiently.
The amount of surface exposed is called surface area. It is the measurement of the total area that the surface of an object occupies.
A small amount of ice generally melts faster than a large amount of ice because of the difference in surface-area to volume ratios. Heat transfer with the surroundings occurs only at the boundaries of the ice. The rate of melting is thus directly proportional to the surface area. Additionally, the amount of ice to be melted is dependent on the volume. The more ice, the longer it takes to melt. Thus, a small cube of ice will melt faster because it has a greater surface area to volume ratio than a large block of ice.
Your lungs provide a very large surface area for gas exchange.

The inner membrane is folded on itself multiple times in structures called "christae". These folds dramatically increase the surface area within the mitochondrion, which increases how much energy the organelle can make.
