A drawing of the leaf was made before the experiment began to provide a baseline reference for comparison. It helps document the initial state of the leaf, allowing researchers to observe any changes or effects resulting from the experimental conditions. Additionally, this visual record can enhance clarity in data analysis and communication of the results.
What else can I help you with?
What happens to a leaf if you put squares of aluminum foil on it for 5 plus days?
nothing happen in my experiment
What would be the conclusion after testing a leaf for starch?
Starch is produced by leaves during Photosynthesis, therefore if the leaf has not been exposed to light then it will not contain starch, and so when tested the Iodine will stay Yellow/Brown. Consequently if the leaf has been left in the light Photosynthesis will have taken place and when tested the Iodine will go Blue/Black showing that Starch is present. Hope this helps :)
Why does water roll off the surface of a leaf?
because the leaf is non polar or Because the leaf is coated in lipid molecules
Is a leaf a tissue or an organ?
Yes, the leaf is considered a plant organ.
What allow gaseous exchange between leaf and atmosphere?
Stomata on the underside of the leaf control the passage of gases into and out of the leaf.
What is mesnt by destarching a leaf?
Destarching a leaf is a method used in an experiment to prove that there is starch exsisting within the leaf, Destarching a leaf is also a preparation used before the experiment, to remove all starches within the leaf-NR
How does oxygen get into the leaf?
experiment to show the presence of in a leaf
What is the color of the leaf at the end of the experiment that test for starch?
the color of the leaf become brown-black after the iodine solution was added.
How do you make a marijuana leaf symbol?
Just by drawing it. Look up images of a marijuana leaf and copy what you see.
What is in a leaf that has died?
the oxygen in the leaf makes the leaf die so it cant breath just like us i know this because i have done an experiment on this.
What is the purpose of the cold water when testing a leaf for starch?
Cold water is used to stop the process of photosynthesis in a leaf. This helps to fix any starch that has been produced in the leaf during the experiment. The cold water also makes the leaf more brittle, making it easier to handle during further steps of the experiment.
What change is observe when a leave was boiled in warm water in a experiment?
When a leaf is boiled in warm water, the heat can cause the cell membranes in the leaf to rupture. This can result in the loss of color pigments in the leaf, causing it to turn pale or translucent. Additionally, the proteins in the leaf may denature due to the heat, leading to changes in the leaf's structure and texture.
What is the gold leaf experiment?
The gold leaf experiment was a famous experiment conducted by Ernest Rutherford in 1909 to study the structure of the atom. He bombarded a thin piece of gold foil with alpha particles and observed that some particles were deflected, indicating that atoms have a dense, positively charged nucleus at their center. This experiment led to the development of the nuclear model of the atom.
What is the season before leaf bare?
leaf fall, or fall
Why to destarch a plant?
a leaf (plant) should be destarched before photosynthesis investigations because the starch already present in the plant may mislead the result . hence if a destarched plant is used for the experiment then the amount of starch present at the time of the experiment will be nil and affter the experiment is compleded the amount of starch present in the leaves woul give the rate of photodynthesis as starch id prepared during photosynthesis
How can you find whether water evaporates from a leaf?
To determine if water evaporates from a leaf, you can conduct an experiment by placing a plastic bag over a leaf or a small branch and sealing it tightly. Over time, you can observe any condensation inside the bag, indicating that water is evaporating from the leaf. Additionally, measuring the leaf's weight before and after a set period can show a decrease in mass due to water loss. Monitoring the leaf's surface temperature can also provide insights into evaporation rates.
What is the texture of a leaf before boiling it in ethanol?
what type of leaf?
