The surface area to volume ratio is crucial for processes such as gas exchange and nutrient absorption. Leaves, being flat and thin, have a high surface area relative to their volume, making them efficient for photosynthesis and gas exchange. Roots, while not as flat as leaves, still have a higher surface area to volume ratio than seeds due to their elongated shape, which is beneficial for absorbing water and nutrients. Seeds are generally more spherical or oval, making their surface area to volume ratio the lowest among the three, as a sphere has the lowest surface area to volume ratio of any shape.
