Introduction
Plants grow and reproduce and in order to do so they need certain resources. Both external and internal resources partly determine the plants development. Common resources are water, space and nutrient obtained from either the plant’s environment or food. They get sugar through photosynthesis using water, light, CO2 and other necessary nutrients. Plants require nutrients to build molecules so reactions can take place that are required for the plant growth, maintenance and reproduction (Rush, Gladilina and Condy 2014). These nutrients usually are taken up by the plant through their roots and leaves. Nitrogen is the most important nutrient to plants, as it is a macronutrient and needed in large amounts for plants (Rush, Gladilina and Condy 2014). Since each developmental stage of the plat has its own nutritional and environmental requirements, the growth and nutrients needed change through the plant’s life cycle. So too much of certain nutrient can have a large affect on the plant (Sims, Pastor, Lee, Dewey 2011).
Today, agriculture and the food industry have a huge part in our society’s development, as it has become an essential part of our economy. The soil farmers use to grow their plants contain nutrients to help the plants grow. Since nitrogen is needed in large quantities by the plant, it is most frequently used as fertilizer. The need for nitrogen depends on the plant. It is considered an organic fertilizer and if added, too much or too little affects the crop growth directly (Whiting, O’Meara, Wilson 2013). In agriculture, the fertilizers of nitrogen and phosphorus can utilize only partly. Having low phosphorus available to the plant is a limiting factor in the plants growth and development as well.

For years farmers have been adding natural fertilizers to their crops. It is a big risk though. Over fertilizing is very dangerous. It puts high concentrations of salt into the soil. It can also affect the water resources nearby. Nitrogen, Phosphate, and Potassium are the basics of fertilizer. If a certain nutrient is short in supply the fertilizer might not work as well. Calcium, iron, manganese are also nutrients that might be needed. So don’t just trust the fertilizer bag that says it has all the nutrients, test it out. (Miller and Levine 717)

The primary nutrients that plants require are carbon, hydrogen, and oxygen from air and water. Sugar has a different effect on animals, humans, and plants. In this experiment, we are testing the effects of sugar on the growth of wheatgrass. For this experiment, we used regular sugar that we put in our food and drinks. To test our hypothesis we are using two groups control and experiment group. The control plant received only water but the experimental plant received sugar but, both plants were placed in the same temperature and same amount of water. Our hypothesis was correct, experiment plant “sugar water” yield more plant growth than control plant “water”. This experiment shows the sugar water plant grow faster than water because of the average of both plants. The sugar water experiment plant had longer in length compared to water control plant.

*** Macronutrients Certain elements in the soil are required by plants in relatively large quantities; these are called macronutrients. Some of these are major components of nucleic acids, proteins, and phospholipids, all of which are plentiful in plants. Among the macronutrients, nitrogen (N), phosphorus (P), and potassium (K) are particularly important because they often act as limiting nutrients, meaning their availability limits plant growth. If N, P, and/or K are added in appropriate quantities to soil as fertilizer, plant growth usually increases. This observation explains why the leading ingredients in virtually every commercial fertilizer are N, P, and K. Freeman 5th***. Both organic and inorganic fertilizers provide plants with the nutrients needed to grow healthy and strong. However, each contains different ingredients and supplies these nutrients in different ways. Organic fertilizers work over time to create a healthy growing environment, while inorganic fertilizers provide rapid nutrition. (REFERENCE/rephrase)
The quality of the fruit or vegetable is improved as the plant obtains all the micro and macro nutrients that are required for that development of the plant. The application of the Inorganic Fertilizer is not required frequently causing less labor and reducing the cost. Organic Fertilizers release their mine...
Humans depend on plants in numerous ways. One reason we depend on plants is for consumption. Plants have the unique ability of producing their own food through a process called photosynthesis. In this process, plants are able to produce macromolecules such as carbohydrates that cannot be produced in animals or humans. In humans, the only to gain these macromolecules is to consume plant matter, or consume plant-eating animals (herbivores).
The findings of the RBT representation for when life first appeared on our planet assist to support the verification for recent life on our planet. These ...
Plants contain a great variety of carbohydrates such as polysaccharides (pentosan, hexosans such as cellulose, starch, xylans, etc.), oligosaccharides (stachyose, raffinose, etc.), disaccharides (maltose, sucrose, cellobiose, trehalose, etc.), monosaccharides (glucose, galactose, fructose, etc.), sugar alcohols (glycerol, sorbitol, etc.), sugar acids (uronic acid, ascorbic acid, etc.), esters (tannins), organic acids (citric, tartartic, oxalic, lactic, etc.), proteins (albumins, globulins, gluten, prolamines, amino acids), lipids (fatty acids, phospholipids, glycolipids, etc.), nucleic acids (purine and pyrimidine), vitamins (fat soluble: A, D, E, K; water soluble: thiamine, niacin, riboflavin,
The global population in the year 2050 is expected to be nine billion and the agricultural demand is expected to double. With the current population already over seven billion people, there are hunger issues all around the world (“New” par. 1). How are we going to deal with food shortages in the future? With less land to work with, strains on the soils, and the lack of water, it is getting harder for the farmers of the world to support our growing population. These complications are making it harder for farmers to produce quality, affordable food. To help the crops grow better, farmers use fertilizers and chemical sprays to enhance growth and control the weeds. Farming in the United States is a relevant business because it supplies people with food, provides people with jobs maintaining the used equipment with the new equipment being much more expensive, and it provides research for more efficient ways on how to feed the world.
Humans are heavily reliant on the diversity of life that occurs on Earth; from the microbes in soil, to oxygen producing plants and pollinating insects, to the animals we eat and wear and to the trees we cut down, reorganize and live in, human existence – as we know it – is completely dependent upon a tremendous diversity of life on this planet. We are going to explore the domains and kingdoms into which life is categorized in hopes of better understanding the unity and diversity of life on Earth.
During this semester I had the chance to study plants at a cellular level, and I had the chance to understand how important they are for every organism. Everything we eat comes directly or indirectly from plants. Throughout human history, approximately 7,000 different plant species have been used as food by people (Britanica-online.com). By a process that only plants can do, called photosynthesis, plants are able to convert light energy from the sun into food. In this process plants are able to create food from a chemical reaction that involves carbon dioxide, water, and sunlight. This process is able to produce sugar(food), and oxygen. The sugar created by this reaction it is what holds the energy that herbivores and omnivores get while eating plants. According to a website called botanical-online.com, “All other living organisms on earth feed on organic matter produced by plants and some lower organisms. First, the primary consumers or herbivores that incorporate food in their bodies produced by plants. For example, a rabbit eats the carrot or a crab larvae consume the tiny plant organisms that float

Plant nutrition is area of plant biology that is of the utmost importance for the proliferation of plants. Without proper nutrition, plants would simply cease to exist unless drastic alterations were made. There are certain elements that are required for the plant to grow and reproduce; these elements are known as essential elements. There are three requirements of an essential element: the element must be required for the completion of the plant’s life cycle, the element must not be replaceable by another element in whole, and finally the element must be direction involved in the metabolism of the plant. Chemical compounds that are involved in proper nutrition have been designated as nutrients, and further classified as macronutrients and micronutrients. Macronutrients are needed for growth, metabolism, and many other functions, but are designated as “macro” because they are required in larger amounts. Macronutrients include carbohydrates, proteins, and fat molecules. Micronutrients have a much wider function that depends on the exact micronutrient. Micronutrients are designated as so because they are needed in much smaller amounts when compared to macronutrients. Examples of micronutrients include vitamins and minerals.
