Sunlight energy 6CO2 + 6H2O C6H12O6 +6O2 The formula for photosynthesis starting from the left side starts with “six molecules of carbon dioxide and six molecules of water as starting ingredients (or” reactants”), and then on the right is a molecule glucose and six molecules of oxygen as product” (Krogh, 2011, p.142). In the middle of the equation is the energy that comes from the rays of the sun. The sunlight is the most important and the driving force behind the entire process. Krogh, D. (2011). Biology: A guide to the natural world (Custom Vol. I). San Francisco, CA: Prentice Hall. C4 plants are will grow more in warm weather.

Then the carbon dioxide is escorted into specials bundle- sheath cells, where rubisco can bind to it, thus initiating the Calvin cycle” (Krogh, 2011, p. 152). This process of photosynthesis uses four carbon molecules. This mode of photosynthesis is less likely to experience photorespiration. Photosynthesis will take place in specials cells during this process. The stomata can remain closed for long periods which will not have an effect on the plant, because it is able to trap oxygen. During CAM photosynthesis carbon fixation takes place at night and the Calvin cycle occurs during the day. This form of photosynthesis occurs mostly in the dessert where water is very limited, it occurs in dry weather plants known as succulents. “ Many dry weather plants employ CAM photosynthesis, in which the plant’s stomata open only at night, letting in and fixing CO2, which is then “banked” until sunrise, when the sun will supply the energy needed to power the Calvin cycle” (Krogh, 2011, p. …show more content…
The differences between C3 and C4 photosynthesis is that C3 photosynthesis use a rubisco that binds with oxygen. Meanwhile C4 photosynthesis contains a different enzyme that binds with carbon dioxide, not oxygen. On the other hand CAM photosynthesis, carbon fixation takes place at night and the Calvin cycle occurs during the day. Also C3 photosynthesis plants benefit from a cool and moist environment with natural sunlight. Photorespiration will likely take place when the temperature rise, the heat will cause the stomata on leaves to close to preserve water. Unlike C3 photosynthesis, C4 photosynthesis benefit from dry, warm, and sunny conditions. At the same time CAM photosynthesis profit from hot and dry climates. Different from C3 and C4, CAM photosynthesis allows carbon fixation only at
The majority of life on Earth depends on photosynthesis for food and oxygen. Photosynthesis is the conversion of carbon dioxide and water into carbohydrates and oxygen using the sun’s light energy (Campbell, 1996). This process consists of two parts the light reactions and the Calvin cycle (Campbell, 1996). During the light reactions is when the sun’s energy is converted into ATP and NADPH, which is chemical energy (Campbell, 1996). This process occurs in the chloroplasts of plants cell. Within the chloroplasts are multiple photosynthetic pigments that absorb light from the sun (Campbell, 1996).
... in the chloroplasts in some of their cells. Chlorophyll allows the energy in sunlight to drive chemical reactions. Chloroplasts act as energy transducers, converting light energy into chemical energy. So as the plant has more light the chlorophyll inside the chloroplasts can react faster absorbing in more light for food and energy.¡¨ So this shows my prediction was correct for in my experiment and shown in my result table and graph the more light intensity there is on a plant the higher the rate of my photosynthesis will be. My prediction is very close to what I said the results will be so my prediction was correct and has been proven to be correct in my result table, graph and now explained again in my conclusion.
Photosynthesis can occur in any green part of the plant. This green part contains chloroplasts. Chloroplasts separate photosynthesis and other cellular activities. The cytoplasm like liquid, stroma, in chloroplast consists of ribosome, DNA, and enzymes which takes part in photosynthesis. There are two stages in photosynthesis: light dependent and light independent. In light dependent stage, by using light energy water is broken into hydrogen and oxygen. In light independent stage, hydrogen reacts with CO₂. Also, water is reformed. This stage both happens when it is dark or light.
Photosynthesis is the process where plants transform light energy usually from sunlight into chemical energy and its balanced equation is 6CO2 + 6H2O –light energy----> C6H12O6 + 6O2 (Elsevier B.V.,LiveScience). Photosynthesis has major byproducts including water, glucose and starch(which is produced in the plant), and last but not least; oxygen. There are numerous amounts of plants all around the world producing CO2 necessary for human survival. However, the photosynthesis cycle is not visible which results in the plants appearing like they are not doing anything. One way to clearly prove that plants are indeed performing photosynthesis is to observe the plants giving off oxygen; which is one of the most important results of
Photosynthesis is the conversion of carbon dioxide, water, and light into chemical energy through a series of reactions, and can occur in plants both on land, and in the water (Ensminger PA 2004). However, a variety of things can affect photosynthesis; water levels, temperature, and light availability are just some of the many that can cause fluctuation in the photosynthetic reaction of plants (Carr et al. 1997). This lab was a result of this observation. With so many factors affecting photosynthesis, interest was expressed about whether water type could affect it as well. This could be important for several reasons. For example, as more and more carbon dioxide gets absorbed into the water on Earth, figuring out which water source provides a better habitat for aquatic plants such as Elodea could lead to further understanding global
During photosynthesis, carbon from atmospheric carbon dioxide is transformed into components which are necessary for plants to live and grow.
Long version: In the stroma, in addition to CO2, two other components are present to initiate the light-independent reactions: an enzyme called ribulose bisphosphate carboxylase (RuBisCO) and three molecules of ribulose bisphosphate (RuBP). RuBP has five atoms of carbon, flanked by two phosphates. RuBisCO catalyzes a reaction between CO2 and RuBP. For each CO2 molecule that reacts with one RuBP, two molecules of 3-phosphoglyceric acid (3-PGA) form. 3-PGA has three carbons and one phosphate. Each turn of the cycle involves only one RuBP and one carbon dioxide and forms two molecules of
Photosynthesis is a series of light driven reactions that convert energy poor compounds such as carbon dioxide and water to energy rich sugars  such as glucose. The process generate an electron gradient across the membrane of a chloroplast, which is used for ATP synthesis, and simultaneously produces electrons used to make NADPH, using NADP+ as an energy carrier. Crudely put, it is the method by which autotrophic plants make their own ‘food.’
“Photosynthesis (literally, “synthesis from light”) is a metabolic process by which the energy of sunlight is captured and used to convert carbon dioxide (CO2) and water (H2O) into carbohydrates (which is represented as a six-carbon sugar, C6H12O6) and oxygen gas (O2)” (BioPortal, n.d., p. 190).
C3 photosynthesis is the ancestral form of photosynthesis and is present in the majority of plant species (Sage, Sage & Kocacinar 2012). In this process CO2 enters the mesophyll cell (mc) via openings in the epidermis called stomata and diffuses into the into the chloroplast where it enters the Calvin cycle (Raven, Evert & Eichhorn 2013). The Calvin cycle is made up of three stages: 1. Carboxylation of Ribulose-1,5-bisphosphate (RuBP). In which a molecule of CO2 is covalently bonded to a molecule of RuBP forming the first stable intermediate 3-Phosphoglycerate. It is from this 3 carbon product that the name C3 photosynthesis comes from. This reaction catalysed by the enzyme Ribulose-1,5-bisphosphate carboxylase-oxygenase (Rubisco) 2. Reduction of 3-phosphoglycerate to the carbohydrate glyceraldehyde-3-phosphate, utilizing the ATP and NADPH formed in the light harvesting reactions. 3. Regeneration of the initial substrate RuBP (Taiz & Zeiger 2006). These stages encompass thirteen different reactions the net result of which is:
Photosynthesis is a process in plants that converts light energy into chemical energy, which is stored in bonds of sugar. The process occurs in the chloroplasts, using chlorophyll. Photosynthesis takes place in green leaves. Glucose is made from the raw materials, carbon dioxide, water, light energy and oxygen is given off as a waste product. In these light-dependent reactions, energy is used to split electrons from suitable substances such as water, producing oxygen. In plants, sugars are produced by a later sequence of light-independent reactions called th...
Photosynthesis is a wonderful process that takes place in nature for examples in plants bacteria and algae. Where it capture the energy from the sun and convert (carbon dioxide and water) to chemical energy and storing it in the bond of sugar (fruits). The process of the photosynthesis takes place in the chloroplasts, specifically using chlorophyll (the green pigment. Human are familiar with the utilized the sun energy by using solar energy system ...
Photosynthesis is a cycle plants go through converting light into chemical energy for use later. Photosynthesis starts in the chloroplasts, they capture chlorophyll, an important chemical needed for photosynthesis. Chloroplasts also take water, carbon dioxide, oxygen and glucose. The chlorophyll is taken to the stroma, where carbon dioxide and water mix together to make
According to scientists, photosynthesis is “the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.” ("pho•to•syn•the•sis,")
