How do you calculate surface area?
The best method depends on the accuracy required of your measurements. If you require accurate and precise results, use a scientific instrument that's specially designed to measure the area of leaves. E.g. AM300 Leaf Area Meter
What is the formula for finding the area of a leaf?
There is no specific formula for finding the area of a leaf as the shape of leaves can vary widely. One common way to estimate the leaf area is by using a grid method, where the leaf is placed on a grid paper and the number of full squares covered by the leaf is counted. This count can then be used to calculate an approximate area. Alternatively, there are specialized instruments called leaf area meters that can measure the leaf area directly.
Formula for calculating the leaf area of lettuca?
ANSWER 1Since this is an irregular surface, you will have to use integration techniques: for example, divide the surface into many narrow strips, consider each strip to be a rectangle and calculate its area as such, add all up. The more narrow you make the strips, the more accurate will be your estimate.ANSWER 2The best method depends on the accuracy required of your measurements. If you require accurate and precise results, use a scientific instrument that's specially designed to measure the area of leaves. E.g. AM300 Leaf Area Meter[See related link below for more information]My AM300 can store the image, and will analyse it to measure all sorts of useful parameters, like perimeter. I need a lightweight instrument which I can carry for hours, and it only weighs 1.8kg . Other models which are called 'portable' weigh 6.8kg!If you do not require a high degree of accuracy, you can use the method described in ANSWER 1. However, you may find it quicker to draw around the leaf, then cut out and weigh the paper. By comparison to the weight of a known area of the same paper, you can calculate the area of the leaf. However, when using methods which involve cutting paper, you must cut around the perimeter extremely carefully. Similarly, you must be highly accurate when weighing. I am not sure that paper - even heavy paper - is heavy enough to make the relative error
What is the unit of leaf area index?
m2/m2
How do you find the area of a leaf?
You times the long stem by the short stem
How do you calculate leaf area duration LAD?
LAD= [(LAI1 + LAI2)/2] x Number of days LAI is Leaf Area Index. That number is usually given, if not it can be found by Leaf Surface Area/Soil Surface Area.
Why calculate leaf surface area with transpiration?
The stomata on the underside of the leaf regulate transpiration. The leaf surface area helps to estimate the number of stomata, which could speed up or slow the rate of transpiration.
Why did you need to calculate leaf surface area in tabulating your results?
transpiration is the loss of water vapour from the leaves of the plant, therefore the bigger the surface area of the leaf, the more water vapour lost from the plant.
How can you calculate the total leaf surface area expressed in cm2 in mm2?
1 cm2= 100 mm2
The leaf surface area is just as if not more important than the intensity of light in photosynthesis?
true
How do you calculate leaf surface area?

How does the large surface area of the leaf help it to make food more efficiently?
the bigger the leaf the more surface area, the more surface area the more food from the sunlight. think about things your brain is capable of figuring things out if you give it the chance
What is the disadvantage to the leaf of being thin and broad?
The flatter and broader the leaf , the more of a surface area it has. the more surface area it has the more space it has for photosynthesis to take place therefor it can gain more nutrients.
How is the leaf adapted to doing his job?
With regards to its shape, leaf has a flat surface area, increasing its rate of absorption of sunlight.
What force causes a leaf to fall more slowly than a penny?
We know that air resistance (or atmospheric drag) is what causes a leaf to fall more slowly than a penny. A large leaf that weighs a much as a penny has a much greater surface area than the penny, and all this surface area means that the leaf has more drag. Though the leaf and penny will be accelerated by the same amount of force (because they have the same mass), the leaf will present all that surface area to the air, and this will set up a condition of high drag.
What is cell wall important in leaf cell?
it is important because if there is no cell wall it would be floppy and wilted because it is like not having any bones and it would not have a shape. it is important for it to have a large surface area so it can do more photosynthesis.
How does the structure of a leaf help with transpiration?
Increasing surface area via capillary action
