began the experiment in my lab manual. To begin‚ I removed set 1 from the refrigerator and compared the distance the dye had diffused in each of the 3 test tubes with the corresponding test tubes of set 2 that had been kept at room temperature. Next‚ I held each tube vertically in front of a white sheet of paper‚ and then used a metric meter to measure how far the dye had diffused from the gelatin’s surface (in millimeters). I then recorded each of these distances in my lab manual. I repeated this step

Center Science Fair “Plants Growth investigation” Student: Daniela Tristan. Teacher: Mrs. Pena. 2010. Title of the project: Plants Growth investigation Abstract: The purpose of this experiment is that by watering more a plant will help it grow more or less. I hypothesized that the plant that will grow the most will be the plant that will be watered the most. Hypothesis If a plant given an unlimited supply of moisture will grow more rapidly than a plant given the recommended

a wide variety of plants and their uses‚ among them the Agave plant. The agave plant was as important to barbacoa as was the fungus Ustilago maydis to the dish Huitlacoche‚ only this plant had several uses beyond the kitchen. Using my own experiences‚ the vast resources online‚ and a quick call to my parents‚ I set out to learn more about the other aspects of this plant‚ such as it’s role in the everyday life of Indigenous people. Like many other desert plants‚ the agave plant is built to survive

Chapter 1 THE PROBLEM AND ITS BACKGROUND Introduction The Philippines is primarily an agricultural country. Most of the citizens that still live in rural areas support themselves through agriculture. One of the four sub-sectors of agriculture is farming. Farming is one of the common forms of livelihood in the county. The rate of the crops produced here in the country shrank as of 1999 according to the Encyclopedia of Nations. One of the main reasons is the industrialization of farms. The farmers

Lab Design Research question: How does temperature affect on the rate of photosynthesis? Variables: Independent variables: temperature of water where the elodea(plant) is going to be placed Dependent variable: the amount of oxygen produced by photosynthesis reaction Control variables: Light concentration entering the beaker Length of the plant Volume of the water to be precise And of the NaHCO3 What is the variable to be controlled. Why does it need to be controlled. How will you

thing made from another‚ leading to two organisms with the same set of genes. In that sense‚ identical twins are clones‚ because they have identical DNA. Sometimes‚ plants are self-pollinated‚ producing seeds and eventually more plants with the same genetic code. Some forests are made entirely of trees originating from one single plant; the original tree spread its roots‚ which later sprouted new trees. When earthworms are cut in half‚ they regenerate the missing parts of their bodies‚ leading to

Introduction: The purpose of the plant growth experiment was to test the affect of plant fertilizer during plant growth. The system we were working with allowed us to test the recommended amount and double the recommended amount of Miracle Grow in comparison to a control of an all natural growing plant. The plants we were testing were radishes We decided on testing the validity of Miracle Grow with radishes to determine if fertilizers are worth purchasing. Hypothesis: If the recommended amount

Separation and Identification of Plant Pigments by Paper Chromatography Biology 1107L Introduction All living organisms require energy for their chemical processes. The ultimate source of this energy is the sun. Plants convert light energy into the chemical energy of sugars. During photosynthesis pigments are used to capture light energy. Pigments of green plants can easily be separated and identified using a technique called paper chromatography. The purpose of this

Claire Graham BSC 2010L November 4th‚ 2015 Effects of Light Intensity and Wavelength on Photosynthesis of Spinach Leaves By replacing the air pockets in spinach leaf disks with a bicarbonate solution and allowing the disks to sit in the solution while being exposed to different light conditions‚ we were able to observe the effects of various light intensities as well as colors on the rate of photosynthesis. As the spinach leaves photosynthesized‚ oxygen pushed out the solution and filled the intercellular

Medicinal plants constitute an important natural wealth of a country. They play a important role in providing primary health care services to rural people. They serve as therapeutic mediators as well as important raw materials for the manufacture of traditional and modern medicine. Substantial amount of foreign exchange can be earned by exporting medicinal plants to other countries. In this way indigenous medicinal plants play significant role of an economy of a country. Past century there has been
