Photosynthesis takes place in the chloroplasts; green organelles inside plant cells. The thylakoid inside Chloroplasts absorb the sunlight energy needed for photosynthesis. The pigment in the thylakoid absorbs light; however, plants reflect green light. This gives plants their color. If different colors of light are shown on spinach leaves and CO2 consumption is measured, then the spinach leaves given green light will consume the least amount of CO2 due to reduced photosynthesis activity.
Oxygenic phototrophs have chlorophyll pigments while anoxygenic phototrophs have bacteriochlorophyll pigments. Bacteriochlorophyll pigments absorb light at longer wavelengths compared to chlorophyll pigments. Bacteriochlorophyll and chlorophyll also have varying side groups on their structures. How do the reaction centers and photosystems differ between cyanobacteria and Chlorobi? Cyanobacteria have photosystems 1& 2 whereas Chlorobi only have photosystem 1.
A. Were the seeds in the “N” tube undergoing both photosynthesis and respiration, only photosynthesis, or only respiration? Use your results in Data Table 2 to support your answer. The seeds in test tube "N" underwent respiration. Respiration is always happening.
Photosynthesis occurs in the chloroplast of plant cells. Respiration differs from photosynthesis because the reactants of respiration
Doriana Spurrell What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively? Purpose: The purpose of this experiment was to see which of the four lights that range across the light spectrum would properly and most efficiently help the spinach leaf perform photosynthesis. Background Information: Photosynthesis is the process in which plants use light energy to transform into chemical energy.
Mitochondria and chloroplast need energy to perform their jobs. Both of them are in plant cells. The reactions take place in these two organelles. The chloroplast has stroma which is a sticky substance where the Calvin cycle happens. Mitochondria is where the Kreb’s cycle takes place.
photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.
We hypothesized that the beaker that is exposed to higher concentrations of light at a shorter distance from the lamp will produce lower amounts of carbon dioxide due to more available light energy. This experiment will show how the light intensity affects the cellular respiration and photosynthesis in the Elodea plant and whether higher light intensity really does prove more photosynthesis, and thus lower amounts of carbon dioxide, will be made. This experiment is important because it could provide evidence on whether light intensities affect the growth of Elodea and could help manage its
The light-dependent reactions begin in the thylakoids of a chloroplast. First, chlorophyll molecules will take in sunlight which releases high-energy electrons. These electrons will then pass through electron transport chains and the proteins within the electrons use the energy to pump hydrogen ions into the surrounding stroma. Through diffusion, which is when molecules go from a area of high
Cellular respiration is a process that takes place in the cells of organisms to convert biochemical energy from the energy stored in bonds of molecules. To convert this energy the cells take nutrients into adenosine triphosphate, also known as ATP then release the waste products to complete the process. The process of cellular respiration is constantly performing due to the immediate consumption of ATP. In order for cell respiration to take place, there are going to be multiple enzymes involved, composed of cofactors (usually inorganic ions such as magnesium) or coenzymes (usually organic molecules). These enzymes are essential to bind its substrates to its active site and either forming or breaking chemical bonds.
Photosynthesis occurs when the solar energy from the sun is converted into chemical energy. The cell wall surrounds the plasma membrane it is made of a macromolecule called cellulose. The cell wall provides protection for the cell to regulating the life cycle of the cell. The cell wall controls the pressure inside the cell called turgor pressure. This is useful because normally the cell would intake water which causes
Cellular respiration is a fundamental biological process that occurs in plants and animals and generates energy. Its chemical equation is 6O2+C6H12O66CO2+6H2O + ATP, the exact opposite of the second stage of photosynthesis (after the first stage during which sunlight is converted into Adenosine Triphosphate (ATP)). The circulatory system transports the glucose (C6H12O6) from the digestive system to the cells, the Oxygen (O2) from the alveoli to the cells, and Carbon Dioxide (CO2) from the cells to the alveoli. In the alveoli, O2 diffuses into capillaries close to alveoli and CO2 does the opposite. O2 and CO2 are transported into and out of the human body by the respiration system.
The purpose of the photosynthesis lab is to identify and observe the colors of pigments in a spinach leaf as they separate on chromatography paper. Photosynthesis is the anabolic process, or the process of making smaller particles into larger ones in metabolism, that plants use to convert reactants such as sunlight, water, and carbon dioxide into products of glucose and oxygen. Photosynthesis occurs in the chloroplasts of a plant cell where chlorophyll, a pigment, is used to allow the process to occur, while factors such as the amount of sunlight, water, and carbon dioxide affect how much photosynthesis occurs. Chromatography is the process of separating chemical mixtures by allowing chemicals to move over another substance (Woodford, 2017).The moving phase, or moving substance, is in one state of matter as it spreads across the stationary phase, or nonmoving substance, in another state of matter to be identified separately (Woodford, 2017). Chromatography works by adsorption, which means that as the molecules pass over the solid, the
Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.
Chloroplasts are organelles that carry on photosynthesis; carbon dioxide diffuses into the chloroplasts in the leaves (Mader, S. 2010). Sugar and oxygen are released during the process. In order to photosynthesize, plants depend on light energy from the sun. The rate of photosynthesis will increase or decrease depending on the colour of light being absorbed, blue light results in the most photosynthesis occur and green light results in no photosynthesis occurring.
