Surface Area and Volume

               The Bay Leaf typically grows on a tree in the Mediterranean region.

What are the Implications of the Surface Area to Volume of a leaf?

At first the leaf starts out with a bigger volume than surface area . As the leaf grows it's cells become larger. This is good because the volume will remain the same as the leaf's surface area begins to grow in numbers. So the Surface area part of the ratio grows over time, but the volume will remain the same. This is good because a larger surface area can catch more sunlight in order to use photosynthesis.

How Would you Calculate the Surface Area to Volume Ratio of a Leaf?

To find the surface area to volume ratio you first must do a few things. To start off you need to find the surface area(ex. 28 square cm.) and the volume (ex. 20 square cm). There for the ratio surface area to volume ratio would be 28:20. (simplify if necessary)

What Instruments Would you use to Find This?

To find the ratio you will need to use a few tools. First you need to collect the leaf you want to measure. Next, you will a line it onto a piece of graph paper and then trace around the leaf. and then add the squares and multiply by two in order to find the surface area. (Graph Paper, a Leaf, Scale, and Pencil) Next, you will need to find the volume of the leaf. To do so you first need to weigh the leaf ( in grams ) then use the formula (volume = weight / two).

What are the Benefits to a
Leaf that has a small Surface Area to Volume Ratio?

If you have a smaller surface area to volume ratio there are a few benefits. One benefit is, the plant won't use as much energy because photosynthesis is taking place in a smaller condensed area. Another benefit to having a bigger volume v.s. surface area is that you can store more water to help speed up photosynthesis even in a drought.

What are the Benefits to a Leaf that has a large Surface Area to Volume Ratio?

There are several benefits to having a bigger surface area to volume ratio. One of those benefits is having a bigger surface to catch more sunlight. Another benefit this would be that with more sunlight the plant would be able to provide more energy to carry out the process of photosynthesis.
