FIXING PEA PLANTS (Pisum sativum) ON GROWTH OF CORN (Zea mays) Introduction Interactions among plant species‚ particularly negative ones‚ have been a concern in agriculture (Levene 1926‚ Russell 1961). Novoa (1981) suggested that it would be advantageous to rotate certain crops by season‚ grow certain crops together‚ or avoid growing certain crops on the same land. Observations indicated that some crops require specific types of nutrients in contrast to other crop species‚ and plants within

Introduction: The rice plant has tillers which are a characteristic of grass plants; however they have recognized a way of growing the plant which causes it to create the best grain possible. Discussion: Vegetative: In this stage the plant germinates and gradually grows taller and leaves emerge at steady intervals. Germination: The root elongates through the seed coat and anchors into the soil. The primary leaf (coleoptile) also elongates and breaks through the seed coat. Early seedling

Chapter 37: Water and sugar transport in plants Water moves from areas of high water potential to areas of low water potential. Water’s potential energy in plants is a combination of (1) it’s tendency to move in response to differences in solute concentration and (2) the pressure exerted on it Plants do not expend energy to replace water that is lost to transpiration when stomata are open and photosynthesis is occurring. Instead‚ water moves from soil and roots to leaves long a water potential

The purpose of this paper is to help analyze or compare pigments from two organisms. Chromatogram is the pattern that the chromatography paper has created from its substances. A retention factor‚ also abbreviated as an Rf value‚ is the measurement of the distance that the sample had traveled. The formula for an Rf value is migration distance of solvent front divided by migration distance of substance. An Rf value is the distance the pigment travels from the original spot‚ which is the dot‚ of solvent

3. Explain how the products of photosynthesis are transported‚ partitioned and allocated during plant growth and reproduction. Photosynthesis has been the focus of much attention than any other physiological process in flora physiology. Photosynthesis is a complex plant metabolic process‚ similar to respiration and fermentation‚ in which a plant can synthesize organic matter using light and chlorophyll. According to Kirk 1994: Photosynthesis is a complex physic-chemical process that is the central
