All of the plants in the nightshade family are nitrogen containing plants, including nicotine. Nitrogen is the second most important supplements for plant growth, below water. Nitrogen can be found in many different forms. It moves around natural ecosystems through the nitrogen cycle. The different forms of nitrogen decide its whether or not it is available to plants or whether it escapes and is no longer able to provide plants. The amount of useable nitrogen and the percent that is lost from the soil affects the supportability of productivity. If it is mishandled it is possible to have economic loss to the producer and have an environmental
impact.
The Effect of Light on the Organic Plant Elodea Aim: To calculate the rate of photosynthesis from the number of oxygen bubbles produced by the plant. Photosynthesis: The process by which green plants use the sun's energy to build up carbohydrate reserves. Plants make their own organic food such as starch. Plants need Carbon dioxide, water, light and chlorophyll in order to make food; and starch and oxygen are produced. Carbon dioxide and water are the raw materials of photosynthesis.
1. In response to light, phytochrome undergoes a change in shape that leads to the activation of
An Analysis and Evaluation of Data from Photosynthesis Experiments Graph analysis This is my analysis for the investigation in to the affect of light intensity on the rate of photosynthesis to the Canadian pondweed, elodea. In the results the pattern is that when the light intensity is higher the readings are generally higher. On the graph the less the light intensity the lower the gradient of the curve. the equation for the photosynthesis process is; CO2 + 2H2O + Light Energy = =
A number of factors can affect the NSC content including the type of plant (grass hays, legume hays, oat hay) maturity of plant (young plants tend to be higher), the environmental conditions (stressed grasses have higher amounts of NSC), the season (spring has largest content of NSC) and time of day (afternoon). The factors mentioned above as well as the curing process will affect the NSC content of forage. The longer hay has being dried the lower the NSC, soaking hay can also remove a large amount of the NSC content.
A seven year-old child lives in China with his mother. This childs name is moonshadow. Moonshadow’s father lives in the United States which Moonshadow calls the land of the golden mountain. He beleivs that the “demons” (white people) live there. Moonshadow has never seen his father because before Moonshadow was born his father started a kite company in the United States to earn some money to benefit them. Suddenly his father calls for him and wants him to come live in the land of the golden mountain with him and work in the kite company. When Moonshadow gets there he is glad to finally spend some time with his father. Others in the company are nice and they show Moonshadow around. Windrider ( moonshadow’s father) treats Moonshadow with lots

The Effect of Light Intensity on Photosynthesis Of Elodea Canadensis Introduction I wanted to find out how much the light intensity affected the Photosynthesis in Elodea Camadensa. I decided to do this by measuring the amount of oxygen created during photosynthesis. Photosynthesis is the procedure all plants go through to make food. This process uses Carbon dioxide, water and light energy. It produces Oxygen and Glucose.
Comparing the Growth of Pea Plants Grown in the Light and in the Dark Aim: To compare the vertical growth and weight gain of pea plants grown in the light and in the dark. Background Knowledge: Photosynthesis forms the basis for this experiment. This is the process by which a plant makes food for itself from the raw materials around it. The energy needed for photosynthesis comes from sunlight, which is the variable for this experiment.
Milkweed is a novel by the author Jerry Spinelli and was published in 2003 by HarperCollins Publishers. The novel follows an innocent boy who gets called Stopthief, Misha, Jack or Poppynoodle throughout the book. The story takes place in Warsaw, Poland during World War II. Misha’s age is not given in the novel but by reading you can tell that he is somewhere around nine years of age. It is no doubt that Misha was not quite like most boys his age. Misha was small, curious and clueless of the world around him and by that time he had stopped growing. Misha had experienced horrible things. He had an astounding imagination and was often clueless of the situation he was in, some which we think benefited him in the war and helped him keeping the right
According to both Daniel Dennett and Mary Ann Warren’s theories on personhood, Samantha from the film “Her” would be considered a person. Daniel Dennett would consider her to be a person because she falls into his six basic conditions of personhood; those include rationality, conscious mental states, and intentionality, being the subject of a special stance of attitude of regard by other persons, reciprocating this person-regarding stance, the capacity for verbal communication and self-consciousness. Rationality is the state of being rational, which ultimately means having a sound judgment of oneself. Samantha displays this quality when Theodore tells her she’s not a person since she has no need of oxygen.
The Significance of the Nitrogen Cycle in Ecosystems Nitrogen makes up about 80 per cent of the Earth's atmosphere as a gas. However the gaseous molecule is very stable and has to be transformed before it can be used by most organisms as it is only available to them when it is ammonium or nitrate. It can only be removed from the atmosphere in two ways: by lightning and by nitrogen fixation. Only a few species can convert nitrogen by nitrogen fixation to biologically useful forms. Due to this, biologically useful nitrogen is often in short supply and can be the limiting factor in an ecosystem.
Photosynthetic pigments are essential for life because they allow photosynthesis to occur by capturing sunlight which is then used alongside carbon dioxide and water to form organic compounds such as glucose and oxygen. The pigments allow the conversion of light energy to chemical energy which other organisms can benefit from. Oxygen is utilised by other organisms in aerobic respiration. The different pigments present in the chloroplasts allow a wide variety of wavelengths of light to be absorbed for efficient photosynthesis and provide colours to the plant to attract pollinators.
Fertilizers are essential to modern industrial agriculture. Two of the most important plant nutrients are nitrogen and phosphorus. Nitric acid, phosphoric acid, ...
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).
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.
