The Effect of Different Colored Light on Plant Growth
In the future, I would put different types of plants underneath the same color of cellophane to see if the light had the same effect that it did on the pole mean plants. I would also weigh the plants to find out their overall mass. I would also find out how much sugar is being produced by photosynthesis Cellophane is a thin, transparent sheet made of regenerated cellulose.

Its low permeability to air, oils, greases and bacteria makes it useful for food packaging. It’s clear, it’s handy, and it’s wrapped around my candy.
The cellophane wrap is one of the most versatile discoveries of the sass. Intended to be a protective textile, the cellophane has since found application in many Industries as a packaging material and as a semi-permeable film. Many people mistake cellophane for plastic. The truth Is the two materials are of completely different composition. Plastic Is a synthetic or semi-synthetic polymer. In contrast, cellophane is a sheet of regenerated cellulose. The only thing that cellophane and plastic have in common is that both materials are usually made into transparent sheets.
Uses for cellophane One of the earliest applications for cellophane wrap is for packaging and storage of food products. This specific function of the cellophane remains to this day, even though some Industries have turned to plastic for the same purpose. Nevertheless, the use of cellophane as a packaging material extends beyond food products. Almost all consumer products are able to utilize cellophane for packaging. I nerve are various toner applications Tort cellophane. Oneself tapes, sun as 3 Scotch tape, use cellophane as a base for their products. There are those who use printed cellophane for gift wrapping.
Cellophane is also used as a semi-permeable barrier for battery cells. Beauty spas employ cellophane wrap for hair and cellulite treatments. In the realm of medicine, cellophane is also used as semi-permeable tubing for dialysis. With such an impressive track record, people will continue to utilize cellophane as an important material for industry. Article Source: http://Centralizes. Com/4264429 How is it made? Unlike the man-made polymers in plastics, which are largely derived from petroleum, cellophane is a natural polymer made from cellulose, a component of plants and trees.
Cellophane is not made from rainforest’s trees, but rather from trees farmed and harvested specifically for cellophane production. Cellophane is made by digesting wood and cotton pulps in a series of chemical baths that remove impurities ND break the long fiber chains in this raw material. Regenerated as a clear, shiny film, with plasticizing chemicals added for flexibility, cellophane is still comprised largely of crystalline cellulose molecules. This means that it can be broken down by micro-organisms in the soil Just as leaves and plants are. Is it earth-friendly?
Cellulose belongs to a class of compounds known in organic chemistry as carbohydrates. The base unit of cellulose is the glucose molecule. Thousands of these glucose molecules are brought together in the plant growth cycle to form long Haines, termed cellulose. These chains are in turn broken down in the production process to form cellulose film used in either an uncoated or coated form in packaging. When buried, uncoated cellulose film is generally found to degrade within 10 to 30 days; PAID-coated film is found to degrade in 90 to 120 days and nitrocellulose- coated cellulose is found to degrade in 60 to 90 days.
Tests have shown that the average total time for complete bio-degradation of cellulose film is from 28 to 60 days for uncoated products, and from 80 to 120 days for coated cellulose products. In lake eater, the rate of bio-degradation is 10 days for uncoated film and 30 days for coated cellulose film. Even materials which are thought of as highly degradable, like paper and green leaves, take longer to degrade than cellulose film products. Conversely, plastics, polyvinyl chloride, polythene, polyethylene transliterate, and oriented- polypropylene show almost no sign of degradation after long periods of burial.
I Introduction Peachy (Brassier ARPA L. C.v. group Pack Choc’) is an erect, biennial herb, cultivate as an annual auto 1 30 m tall In vegetative I Stage. Ovate leaves are ranged spirally and spreading. The petioles are enlarged and grow upright forming a subliminally bundle. I luminescence is a raceme with pale yellow flowers. Seeds are 1 mm in diameter and are reddish to blackish brown in color. I Uses and Nutritional Value I Peachy is used mainly for its immature, but fully expanded tender leaves. The succulent petioles are often the preferred part. It I list used as main ingredient for soup and stir-fried dishes.
