Introduction
Anhydrous ammonia is used for a lot of different purposes, including dehydrating items like food. Dehydration keeps items fresh, save space, and doesn’t require refrigeration to preserve food. Plant and animal cells are similar in some ways but different in their cell wall structure. This could affect how easily the cells can be dehydrated.
Ammonia
The formula for ammonia is NH3. Ammonia is a compound of nitrogen and hydrogen. Ammonia is a non-toxic, colorless gas. It is known for its irritating odor. It is extremely soluble in water. If one is going to breathe in ammonia make sure it is heavily diluted. If mixed with metal it makes a compound called ammines. During evaporation 1 gram of anhydrous ammonia requires 327 calories of heat. Ammonia is used in a lot of things.
Uses
Ammonia with more nitrogen is used for crop production. Ammonia also makes alkaline. Ammonium hydroxide is used in house cleaners and artificial fertilizers. It is used in dynamite, TNT, and other explosives. It is used to dye and scour wool, to make nylon, cotton; it is also in some vitamins, plastics, drugs, and chemicals. Anhydrous ammonia is also used for a lot of useful things.
Anhydrous Ammonia
Anhydrous means without water so when it touches something with water in it; it takes out all the moisture. Anhydrous ammonia is 82% nitrogen. It has to be handled by workers who have been educated on how to correctly use this dangerous chemical. The liquid state of the anhydrous ammonia has to be stored in tanks. The tanks have to be able to stand pressures of at least 250 PSI (pounds per square inch). If a valve is opened for the liquid to get out it turns it into the gas and can get into your body. Anhydrous ammonia is used for quite a few things.
Uses
Anhydrous ammonia is used in a lot of fertilizers and ice packs. If there is a mold growth in grain with high moisture, then some people put anhydrous ammonia on it. All the moisture will be removed and the mold will go away without the moisture. It is also used to keep crops cold while they are in storage getting ready to ship to stores. One reason anhydrous ammonia is used is for dehydration, which is a way of preserving food.
Preservation
Today someone can go to the store and pick up almost any kind of food that is preserved in some kind of package or container. Before preserving food was an option the food someone could get from the store had to either be fresh or there was probably something wrong with it because bacteria had most likely attacked it. The three main ways of preserving are freezing, canning, and dehydrating or drying.
Dehydration and Drying
Drying has been used for a very long time. Some of the reasons we have dehydrating and drying is to keep food items fresh, to save space, and dried food doesn’t have to be refrigerated.
Cells
Most cells are so small you can only see them under a microscope. All cells have a specific job to do. Cells are like people with some things, like they need oxygen to live and need to get rid of the carbon dioxide that comes in with the air. All cells will eventually die too. There is a membrane outside every cell. The nucleus is the thing that controls genetic program. Outside the nucleus is the cytoplasm. DNA stands for Deoxyribonucleic Acid. All plants, animals, and humans have lots and lots of cells.
Plant Cells
Plant cells are unique among eukaryotes. Chlorophyll gives plants their green color. It also makes it so the plants use sunlight to turn water and carbon dioxide into sugar and carbohydrates, which they use for fuel. Plant cells have a protective cell wall like prokaryotic ancestors. Plant cells don’t have centrioles, lysosmes, cilia or flagella unlike animal cells. They do have chloroplast, central vacuole, plasmodesmata, and a rigid cell wall. There are about 250,000 species of plants. A small percent of plants are used for human needs, such as food, shelter, medicine, and fiber. Plants are the basis for the food web and ecosystem. Without plants no animals or human would have evolved. Animals also have a lot of cells.
Animal Cells
Animal cells do not have a cell wall. An animal cell’s nucleus and organelles have a membrane surrounding them. Animals have a greater variety of different cell types, organs, and tissues. All organisms in animals are incredibly different. Three quarters of the earth species are animals. Plants can make their own food but animals are unable to produce their own food so they rely on plants for a lot of things.
Summary
Dehydration has been used for centuries to preserve items, especially food, and to save space. Plant and animal cells are similar but different in their cell wall structure, which probably affects how easily the cells can be dehydrated. Anhydrous ammonia is used for several industrial purposes, often to remove water from items. With care it could be used for dehydrating food.
