Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate

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 route in the global carbon cycle serving as single prevalent flux of organic carbon in the biosphere. More so‚ it specifically involves the assimilation

Collecting Photosynthetic Rates in Spinach (Spinacia oleracea) Introduction: The purpose of this study was to see which light color would cause the spinach sample to photosynthesize the most within the given time. In order to understand photosynthesis‚ we need to know that chloroplasts absorb light energy from the sun‚ the plant then takes that energy along with water and carbon dioxide and changes it to sugar and oxygen. This happens in order for the plants to grow. But‚ light energy comes in a

energy. (http://www.yourdictionary.com/photosynthesis) Photosynthesis actually takes place in the stomata where carbon dioxide and oxygen enter and leave the plant. Chlorophyll is the green pigment of leaves and plants that’s in charge of absorbing light for photosynthesis. (http://dictionary.reference.com/browse/chlorophyll) All chlorophyll plants require sunlight‚ but in very different amounts‚ which should be considered when coping with sun and shade leaves. Hypothesis It is predicted that the

Elodea & Photosynthesis Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. Introduction This lab has been created in order to find what extent does distance from a light source (5cm‚ 10cm‚ and 15cm) affect the rate of photosynthesis (measured in bubbles / 3 min) in Elodea water plants. Hypothesis:

Light energy oxidizes H2A (light reaction): 2H2A ⎯light → 2A + 4[H] ⎯ 2. The reducing agent [H] reduces CO2 (dark reaction): 4[H] + CO2 ⎯→ CH2O + H2O A. Absorption of light - The principal photoreceptor is chlorophyll (Chl) derived from protoporphyrin IX. - Major differences between chlorophyll and hemes are: - Chl has an extra ring (V) (cyclopentanone). - Ring IV of Chl is more reduced. -

main stages in photosynthesis - light-dependent and light-independent stages. [11] The light-dependent stage depends on the light because the energy from the light is used to split water in the process of photolysis and excite electrons in the chlorophyll. [11] The products from the light-dependent stage are ATP and the electron acceptor - reduced NADP. [11] The products from the light-dependent stage are fed into the light-independent stage of photosynthesis‚ the Calvin cycle. [11] Carbon dioxide

DEVELOPMENT OF THE INTERNODE LENGTH OF VIGNA RADIATA WHEN GROWN UNDER DIFFERENT LIGHT INTENSITIES ABSTRACT Throughout their growth plants exhibit varying ways to adapt and change depending on their circumstances‚ with changes in the amount of available light being a major factor in plant growth. The aim of the study was to determine whether there are significant differences in the growth patterns of Vigna radiata when grown under varying light intensities. Plants were grown in two different light
