Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)

The Alveoli
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
So it is more efficient.
No, we need many, many alveoli to give the surface area needed for gas exchange.
You have barile? Lungs have hierarchical structure which minimizes volume but maximises surface area Aveoli are the smallest units of structure and are the site of gaseous exchange: - They are circular = max surface area for min volume - Their most surfaces faciliate the exchange of gases - They have extensive blood supply which also faciliate the exchange
Your lungs provide a very large surface area for gas exchange.
No
Because a pin has a small surface area and a boat has a large surface area.

The skin is an organ in the body that has a large surface area as it covers the entire external surface of the body.
large area
To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
Radiators have a large surface area to increase heat transfer efficiency. The greater surface area allows for more contact between the hot water or steam inside the radiator and the surrounding air, resulting in more effective heat dissipation into the room.
No.Plant roots have large surface area,roots have root hairs to increase the surface area so that large amounts of water can be absorbed easily.
It is important that the gills of a crayfish give them a large surface area because it helps the crayfish to breathe. The bigger the surface area, the more oxygen in the crayfishes system.Ê
