This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll "a". A second kind of chlorophyll is chlorophyll "b", which occurs only in “green algae” and in the plants. Bibliography: http://www.ucmp.berkeley.edu/glossary/gloss3/pigments.html Conclusion: I learned various things from this lab. For instance, I learned how pigments absorbed strongly move slowly and pigments absorbed weakly move the fastest.
According to Hopkins (2006), photosynthesis is the process by which green plants and certain organisms transform itself from light energy into chemical energy. As a straight forward chemical reaction in which carbon dioxide comes from the air, along with the midair and water from the soil, photosynthesis conglomerates to produce what is known as carbohydrate (p. 6). Solar Energy produced by photosynthesis, stores itself in a chemical bond of a carbohydrate molecule. Sugar known as glucose is then formed which becomes convenient both by way of energy to be stored for later use in tissues or by way of carbon to be used for cells (p.7). Hopkins, w. G. (2006).
In plants the way they get there energy is through sun light where they have process called photosynthesis where they produce and release oxygen in the air. Photosynthesis requires direct sunlight, carbon-dioxide, and water. In this process of photosynthesis, plants decompose the molecules of hydrogen and carbon dioxide into hydrogen, then carbon and oxygen produces glucose which forms their source of energy, food and growth. Solar cells similar to this process get sunlight where light in the form of photons hits the solar cell and are absorbed by semiconducting materials such as silicon. Negative electrons are break free from their atoms, causing them with an electric potential difference.
pGLO can also control the gene expression of this fluorecent protein. This GFP protein can be switched on when in the presence of arabinose sugar. transferred cells will appear white on the plates not containg the arabinose, and fluorescent green when arabinose is present. Data and Results: Conclusion: the control plates consisted of the -pGLO LB
Comparing the Growth of Pea Plants Grown in the Light and in the Dark Aim: To compare the vertical growth and weight gain of pea plants grown in the light and in the dark. Background Knowledge: Photosynthesis forms the basis for this experiment. This is the process by which a plant makes food for itself from the raw materials around it. The energy needed for photosynthesis comes from sunlight, which is the variable for this experiment. The substance that absorbs sunlight is chlorophyll, which is mainly contained in chloroplasts.
Photosynthesis is the process when plants and some bacteria use the sun lights energy to produce glucose from carbon dioxide and water. carbon dioxide + water- sunlight- glucose + oxygen Energy in the form of light is the definition of electromagnetic energy. Any visible light like light bulbs, electromagnetic energy can take the form of it. The energy is being absorbed to break bonds making the process endothermic. When energy is being released making new bonds formed is called the exothermic process.
2.2. 1- Phloem tissue is adaxial because conducts sucrose and other organic compounds throughout the plant. 2- Xylem tissue is abaxial because it conducts water and dissolved minerals up from roots. 2.3. 3 2.4.
1. State an advantage having more than one type of photosynthetic pigment gives a plant. Plants with more than one type of photosynthetic pigment will be able to absorb different spectrums of light. 2. Explain the chemical role of water in photosynthesis.
CnH2nOn + nO2 + ADP + Phosphate (+ oxidizing agent and energy from photon [through electrochemical gradient]) → ATP + nCO2 + nH2O Function Carbohydrates play a variety of extensive roles in all forms of life: Carbohydrates are initially synthesized in plants from a complex series of reactions involving photosynthesis. Store energy in the form of starch (photosynthesis in plants) or glycogen (in animals and humans). Provide energy through metabolism pathways and cycles. Supply carbon for synthesis of other compounds. Form structural components in cells and tissues.
The Action Spectrum and the Absorption Spectrum Introduction: The purpose of this experiment is to learn the rates of photosynthesis under different lights, and the absorbance of photosynthetic pigments in spinach extract. “There would be no biology without photosynthesis. Plant biomass is the food and fuel for all animals. Plants are the primary producers. These amazing organisms are capable of capturing the energy of sunlight and fixing it in the form of potential chemical energy in organic compounds.” (Measuring the rate of photosynthesis) “Light is one of the main factors that affects the rate of photosynthesis, which literally means using light to create something new.” (What Are Three Factors That Affect the Rate Which Photosynthesis Occurs?)
