Hypothesis: If one-day pinto bean seedlings are soaked in a water solution, 1% NaCl solution, and 3% NaCl solution, the seedlings exposed to higher sodium concentrations will have decreased cellular respiration rates. Treatments: This experiment involved three treatments and a control. The goal of the experiment was to see how different levels of NaCl affect the rates of cellular respiration in day-old pinto bean seedlings.

The goal of this experiment is to find out what is the identity of the unknown hydrate? To answer this question first, we should know what a hydrate, and how to identify a hydrate using the law of constant proportions. A hydrate is a pure substance because it contains water molecules embedded in its crystal structure that does not vary. By heating the unknown hydrate, we can calculate the mass of the hydrated, and the percentage of water in the hydrate.

For example, Sphagnum Moss obtains the minerals it needs (calcium, sodium, potassium and magnesium) by exchanging ions with the environment (Ecoscope: For Sustaining Wetlands). Hydrogen ions are exchanged with the cell wall of Sphagnum and this is called cation exchange. Since hydrogen ions are dissolved into the water, it becomes more acidic. The Sphagnum gains it minerals this way as bogs are mineral poor. Soil that has higher rates of cation exchange are more fertile that the soil that does not.

ABSTRACT To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. In this experiment we examined how increasing the volume of the extract added to the reaction would affect the rate of the reaction. The enzyme used was horseradish peroxidase which helps catalyze hydrogen peroxide. Using different pH levels, the absorbance rate of the reaction was measured to see at which condition the enzyme worked best. The rates of absorption were calculated using a spectrophotometer in 20 second intervals up to 120 seconds.

Farmers turned to fertilizer, which contains Nitrates. Nitrates also known, as NO3 is a natural compound made of oxygen and nitrogen (Chern, 1999). Nitrates can be found in the air, soil, water, and plants (Johns & Yaremcio, 2004). Much of the nitrate in our environment comes from decomposition of plants and animal wastes (Partnership For Environmental Education and Rural Health, 2015).

Catechol oxidase is found in cell cytoplasm, their function in plants are to "help protect damaged plants bacterial and fungal disease." The objective of this experiment is to test the presences of catechol oxidase in various fruits and vegetables. Our group hypothesis states that, If catechol oxidase is present in the selected extracts, the null hypothesis is that catechol oxidase is not present in the selected extracts. Next, the prediction would be, if catechol oxidase doesn't differ with other enzyme sources, then the rates will

Phosphate and nitrates are examples of polyatomic ions. Polyatomic ions, also known as molecular ions, are charged chemical species composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting to a single unit. Phosphates and nitrates are found in fertilizers and some detergents. When rain dissolves these materials make their way into the creeks and rivers. When the surface waters are rich with these materials, they can cause algae to grow, which completes with other organisms for light and other nutrients.

This experiment will also show if fertilizers help a plant grow more than just soil found in nature. This experiment will not try to prove if chemical fertilizer is safe or not. The chemical fertilizer being used was randomly chosen and the compost will be made from scratch. There are positive and negative effects on the plant from using both these fertilizers. The best result will be determined through daily measurements and general observations of the appearance of the

Natural soil can be used for indoor growing of many types of plants, including fruits and vegetables, but is not ideal. The indoor grower then uses what are known as soilless mixtures. When growing indoors, the water and nutrients come from the grower rather than the natural sources in wild soil, so root systems should be able to thrive without extending out too far, facilitating growing of the plants in garden pots. Applicant will be using a Hydroponic, soilless growing medium containing a mixture of Organic Coconut fiber mix that contains other natural ingredients like sphagnum moss, Vermiculite and Perlite.

Calcium is a necessary component in all things living and is also abundant in many non-living things; particularly those that help support life such as soil and water. Teeth, bones, seashells, and cave stalactites (icicle-shaped formations found in underground caves) are all products of calcium. Calcium seems to be fifth no matter where it goes, it is the fifth most abundant element by mass in the earths crust, most abundant dissolved ion in seawater and the most abundant element in the human body. Calcium is never found in its pure state but it can be found in a variety of minerals including limestone, gypsum, and fluorite.

Differences in nutrient can change yield in sweet sorghum. Magnesium is one of the most important minerals in the structure of chlorophyll for harvesting of solar energy and synthesis of nucleic acids (Wiedenhoeft, 2006). Its roles are more related

How do mycorrhizae affect plants? many mycorrhizal spores are usually present in the organic matter that is close to the surface of healthy soil, and they typically multiply where there is moist and aerated conditions .If the hyphae of the spores meet with the roots of plant which then provide the hyphae with chemical cues like organic acid that leads to mycorrhizal growth, the hyphae will break through the cell walls to the cell membrane forming chemical passageways between the soil and the plant. Mycorrhizae then get soil water and nutrients from pockets that are inaccessible. it is important to say that mycorrhizae do not colonize to a specific plant or at specific time ;however, they colonize most of the plants and have multiple host at different times .they can work as an intermediate between roots of different species and help in carrying nutrients to the plants with dire need , also they stabilizes the soil ,increase its aggregates and promote in organic matter decomposition .Thus, ending up in a fungal freeway network where nutrient and water can reach plants easily.

This promotes hearty, disease-resistant growth. Plants with not enough potassium have less growth and the leaves tend to grow close together. Too much potassium can lead to calcium and magnesium deficiencies. Calcium is a vital component in cell walls of plants, and also essential for root growth. Magnesium is very important for chlorophyll production and also plays a vital role in most enzyme reactions.

Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.

LITERATURE REVIEW Inorganic fertilizers provide rapid nutrition and give plants with the nutrients needed to grow healthy and strong. Inorganic fertilizer, also called as synthetic fertilizer, is manufactured artificially and contains minerals or synthetic chemicals and it is which help a plant to grow faster. Effective use of Inorganic Fertilizers Effectiveness in using these chemicals has good and bad effects on the environment especially on the health of a human being. Fertilizer has turn into essential to modern agriculture to feed the growing population.
