Photosynthesis is used by plants to harness solar energy while a semiconductor-based solar cell harnesses solar energy which converts in to electricity required by all humans. As we explore our world, I would like to compare and contrast these two systems. In doing so, I will describe: 1. Three ways in which the plant cell and the solar cell are similar to each other. 2.
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.
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.
Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.
Form structural components in cells and tissues. Photosynthesis is a complex series of reactions carried out by algae, phytoplankton, and the leaves in plants, which utilize the energy from the sun. The simplified version of this chemical reaction is to utilize carbon dioxide molecules from the air and water molecules and the energy from the sun to produce a simple sugar such as glucose and oxygen molecules as a
Energy is not distributed evenly through the ecosystem; lower levels gain more energy than higher ones. Most ecosystems rely on the sun for energy and for the plants (producers) to convert it into energy to be passed along to primary consumers, and from primary consumers to secondary consumers and so on. The producers are autotrophs and photosynthetic organisms that can perform photosynthesis in order to grow. Consumers are heterotrophs and feed on other organisms, be it plant or animal. There is another type of organism that cleans up after the others, and they are called detritivores.
The nuclear reaction of the sun travels outward and by the time it reaches the surface it is transformed into light energy (sunlight). When this energy reaches the Earth, it is in the form of heat and light. The heat from the sun is collected by one type of solar panel that is used to heat water for the home or to keep your house warm in the winter months. The light energy from the sun can be transformed into electrical energy to be stored or used immediately. The panel that converts light energy into electrical energy is called a Photovoltaic panel.
The light energy that I use comes both from the sun and from electricity. The energy from the sun is captured through solar panels that transform it and make it able to power the electric system of my house. The power plant of
Both ATP and NADPH are responsible for the reduction of glycerate-3-phosphate into triose phosphate, which is converted into many useful organic compounds like carbohydrates, mainly glucose. Although glucose can be used as a direct energy source by plants, it cannot be used directly by animal cells as a source of energy. Instead, cells use ATP as their immediate source of energy. The conversion
The sun radiates solar energy towards earth. Some of this energy gets absorbed by the earth’s surface and some energy is radiated back into space as long wave energy. Certain gases in the atmosphere prevent this reflected energy to pass; they trap the energy and thereby warm the atmosphere and the surface of the earth just like in a greenhouse. Therefore, those gases are known as greenhouse gases (GHG). The main GHGs within the atmosphere are Carbon dioxide (CO2) and water vapor (H2O).
