What happens to a leaf if you put squares of aluminum foil on it for 5 plus days?
nothing happen in my experiment
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.
How does CO2 get to the leaf?
(brooke,13) water is soaked up through roots & carbon dioxide is just absorbed Carbon dioxide is absorbed by the following process. There is a spongy mesophyll, a loose tissue with many air spaces between its cells. These air spaces connect with the extrerior through stomata porelike openings in the underside of the leaf that allow carbon dioxide and oxygen to diffuse into and out of the leaf.
What metal is used as silver foil?
depends on foil:aluminumgold (usually called leaf not foil, most common use is lettering on leather bound books)silver (usually called leaf not foil, most common use is lettering on leather bound books)tin (used for purpose aluminum foil is used for, rarely seen today)lead (often used in roofing to prevent leaks from pooling water, thick for foil)etc.
What happens to a leaf if you put squares of aluminum foil on it for 5 plus days?

What is difference between sheet and plate and foil?
Extremely thin thicknesses are considered foil or leaf. The aluminum foil is a solid sheet of aluminum (or alloy rolled to a thickness of 0.0059inches or less). At a thickness of 0.006inches or more it is referred as sheet and thickness more than 6 mm (0.25 in) is considered as plate.
Which element is rolled into a foil?
Lots of elements can be rolled very to make a foil:gold - used as gold leaf for gilding wood and many other objectssilver - much cheaper than gold and was used to wrap things beforealuminum came along - used to wrap food, chocolate, etc.
How do you remove chlorophyll from other components in a plant exract?
By placing the leaf in the boiling water. by putting aluminum foil on the leaf while the plant is growing. (not sure, but maybe by placing the plant in dark where sunlight cannot reach)
What physical property is described when aluminum can be hammered into thin sheets?
Yes. Aluminium is a metal and a very malleable (can be hammered into sheets) metal as well. To prove this, 'tin' foil used to wrap food for cooking (like 'Bacofoil') is actually made from aluminum and not tin. The most malleable metal is gold - it can be hammered into thin 'gold leaf' sheets that can be so thin that they are just a few atoms thick. Aluminium is not as malleable as this, but it can easily be made into foil.
Will photosynthesis take place in foil covered leaf?
no because the leaves or anyother part of the plan has to be exposed to the sun so the energy from the light will hit the plant and it can crreate sugar to supply energy (with carbon dioxide as well)
How does starch's location in leaves prove photosynthesis?
To clarify: We boiled alcohol with a leaf and tested for starch with iodine (present in the veins), We also covered a leaf with tin foil and came back the next day. The leaf was more green in the veins and more discolored farther away from the veins. This lab was suppose to show us glucose is made by the leaf, but all it proves is that starch is in the veins, right?
Who created aluminum?
Depending on your religious background, either God created aluminum or nothing/nobody did. It's naturally occurring and the most common metal in the earth's crust. Unfortunately, it's never found as the free metal as it reacts readily with other chemicals in the earth. It's most commonly found in the ore called bauxite. If you mean, "who coined the name aluminum as a pure form of the metal?", then Humphry Davy did this in 1808. By the way, I'm British, so I really do spell aluminum this way. ------------------------------------------------------------------------------------------That above answer is incorrect the metal foil has been around for centuries. Foil is solid metal that has been reduced to a leaf-like thinness by beating or rolling. The first mass-produced and widely-used foil was made from tin. Tin was later replaced by aluminum in 1910, when the first aluminum foil rolling plant "Dr. Lauber, Neher & Cie., Emmishofen." was opened in Kreuzlingen, Switzerland.The plant, owned by J.G. Neher & Sons (aluminum manufacturers) started in 1886 in Schaffhausen, Switzerland, at the foot of the Rhine Falls - capturing the falls' energy to produce aluminum. Neher's sons together with Dr. Lauber discovered the endless rolling process and the use of aluminum foil as a protective barrier. From there began the wide use of aluminum foil in the packaging of chocolate bars and tobacco products. Processes evolved over time to include the use of print, color, lacquer, laminate and the embossing of the aluminum.Reference: http://inventors.about.com/od/astartinventions/a/FamousInvention.htm
What will happen to young leaf covered with carbon paper for one week?
the sides of the leaf will wither. because of the lack of sunlight
What leaf cells are covered in wax?
The epidermises, the outer layers of the leaf, are covered in a wax-like layer.
What is foil paper?
Foil paper is a thin, metallic sheet typically made of aluminum that is often used for wrapping or covering food items to help retain heat, prevent moisture loss, or protect food during cooking. It is also commonly used in crafts and for decorative purposes.
