of fertilizers on plant growth | | | Year 11 Biology Year 11 Biology Abstract An investigation was carried out to compare the effect between inorganic and organic fertilizers on plant growth. Tomato seedlings were used‚ which were divided into 3 groups - the inorganic fertilizer group‚ the organic fertilizer group and the control group. Besides using different fertilizers‚ all of the seedlings were planted in the same condition. The result has shown that the plants using organic fertilizer

for both genotypes. However‚ seedling length and germination percentage was better in NM 19-19 as compared to Azri mung-2006. Elevated levels of protein were observed under metal stress in both genotypes. Heavy metals induced oxidative stress in plants‚ causing membrane injury as observed by enhanced level of malondialdehyde (MDA) contents. Increase in antioxidant enzymes activity was detected for guaiacol peroxidase (GPX) and catalase (CAT). However‚ ascorbate (APX) activity decreased under stress

The main parts of the plant circulatory system are xylem and phloem. Humans and plants rely on their circulatory system a great deal. Plants and humans rely on their circulatory system to supply the body or plant with nutrients‚ humans to transport oxygen throughout the body‚ and plants to carry carbon dioxide throughout the body. The circulatory system in both humans and plants also help the body eliminate waste from the body of plants and humans. The xylems in plants are vessels‚ starting with

Experimental Plant Variety In order to have a suitable variety of plant types to successfully complete this experiment‚ plant types that contained recognizable traits and that would not easily be pollinated by foreign pollen were chosen. Finding a plant variety with such characteristics allowed better control over the experiment. Twenty-two varieties of pea plants were chosen by first trialing thirty-four varieties. For two years‚ only self-pollination was allowed for each of these thirty-four plant varieties

Paper How Caffeine effects plant growth. I decided to base my project on the effects Caffeine has on plants. I choose three different Basil herb plants and will water them with a little‚ medium and large amounts of Caffeine to determine the effects that Caffeine has on the plants. What is Caffeine??? Caffeine is found in seeds‚ leaves and the fruits of some plants‚ where it acts as a natural pesticide. Humans mostly extract Caffeine from the bean of the coffee plant and the leaves of tea bushes

Although we have many drugs of mineral and animal origin form nature‚ semi synthetic and synthetic substances‚ plants of various species are almost the major exclusive source of natural drugs for the majority of the global population now a days.

nuclear power plants? Energy is a controversial topic in the United States and the rest of the world. More than half of the energy we have comes from coal burning power plants. President Obama is working along with government agencies to build more nuclear power plants in the United States. Nuclear power plants produce large quantities of energy creating no air pollution and very little water pollution in the form of thermal pollution. The United States should build more Nuclear power plants‚ they are

Nuclear Power Plants and Safety Since the humans use energy sources such as wood‚ coal‚ and oil to produce electricity‚ people want to use better energy sources to produce electricity more. By the mid twentieth century‚ scientists found the method of making incredible energy by using uranium as nuclear fission. Today there are about 400 nuclear power plants around the world and more than 100 nuclear power plants in United States (Howstuffworks). In addition‚ nuclear reactors produced a lot of

Treatment A will be the control variable represented by Sunflower (plant proven able to perform phytoremediation). The other treatments B‚ C‚ D will be obtained from Lagundi (Vitex negundo) plants. The treatments will come from different areas be exposed in different toxic substances such as lead and aluminium. II. Sample preparation Having Lagundi (Vitex negundo) plants will be the initial step in conducting the experiment. The plants will be spoted at Cataggaman Nuevo Tuguegarao City (residence of

Introduction For this Science assignment‚ I chose to find out if the color of light a plant receives‚ affects the plant growth. Light is electromagnetic radiation that comes in waves‚ the basic units of which are called photons. Plants use light to turn carbon dioxide into sugars necessary for growth‚ a process called photosynthesis. Sunlight is a full spectrum of different wave lengths of light. Seen through a prism‚ this spectrum turns into bands of color: red‚ orange‚ yellow‚ green‚ blue‚ indigo
