Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth¡¦s atmosphere. Factors that affect photosynthesis are light intensity and wave length, carbon dioxide concentration, and temperature.
Plants are autotrophs that mean they are able to synthesize food directly from inorganic compounds, instead of relying on other organisms. They use carbon dioxide gas and water to produce sugars and oxygen

The surface of the leaf is uniformly coated with a water-resistant waxy cuticle that protects the leaf from excessive absorption of light and evaporation of water. The transparent, colourless epidermis layer allows light to pass through to the mesophyll cells where most of the photosynthesis takes place.
To metabolic pathways involved in photosynthesis are light reaction and dark reaction. The first stage of the photosynthetic system is the light-dependent reaction, which converts solar energy into chemical energy. Light absorbed by chlorophyll or other photosynthetic pigments is used to drive a transfer of electrons and hydrogen from water to and acceptor called NADP , reducing it to the form of NADPH by adding a pair of electrons and a single proton. The water or some other donor molecule is split in the process. The light reaction also generates ADP, a process called photophosphorylation. ATP is a versatile source of chemical energy used in most biological processes. The light reaction produces no carbohydrates such as sugars.
In photosynthesis, the dark reactions are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions unlike light-dependent reactions do not need light to occur. These reactions take the products of the light-dependent reactions and perform further chemical processes on
The light reactions also generate ATP by using chemiosmosis through a process called photosphorylation. The light energy is converted into chemical energy in the form of two compounds, which are NADPH and ATP. The Calvin cycle occurs with the incorporation of carbon dioxide into organic molecules in carbon fixation. In this process, the fixed carbon is reduced with electrons provided by NADPH. The Calvin cycle takes place during daylight hours, in which the NADPH and ATP can be provided. The Calvin cycle occurs in the stroma, while the light reactions occur in the thylakoids.
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms ' activities. Plants need photosynthesis to survive. The balanced chemical equation for photosynthesis is 6 CO2 + 6 H2O ? C6H12O6 + 6 O2. In English terms, this equation translates to six carbon dioxide plus six
Photosynthesis is the process in which plants use the sun’s light energy to convert carbon dioxide and water into carbohydrates such as glucose, sucrose, starch and cellulose.
Photosynthesis is the chemical process of capturing light energy and converting it into a chemical form. Through a series of reactions, the process takes sunlight, carbon dioxide, and water to produce oxygen and a carbohydrate, usually a sugar called glucose. The oxygen is released into the atmosphere, while the glucose is stored inside the plant. Because sunlight is required, photosynthesis is a diurnal activity.
We need photosynthesis because photosynthesis makes air for us to breath. Photosynthesis makes food by taking in our Carbon Dioxide, water, and sunlight to make our sweet glucose/sugar that we eat every day. Photosynthesis cycles matter in and out of organisms by making glucose that we and other organisms eat then we go to the bathroom and the fluids mix with the groundwater and then it happens all over again. Photosynthesis cycles energy thru ecosystems by taking in carbon dioxide and making it into oxygen that we breath. I know this because in the article Modeling photosynthesis it says that Plants are producers. This means that they can produce food using light energy instead of having to eat, or get nutrients in other ways.
There are three reasons why plants grow because because of water and photosynthesis. To begin with, palisides are are the cells that contain chloroplasts. Palisides are found under a leaf because chloroplast are sticky and sinks through the leaf and sticks and stays under the leaf. Additionally, glucose is a sugar that plants create to feed themselves. If the plant doesn’t have sunlight, soil, and water, the plant can’t form glucose. Next, chloroplasts is a plastid in the cell that forms glucose through photosynthesis. Chloroplasts forms glucose so the plant can eat. As a result, plants can grow in many different ways if it has water and can do photosynthesis.
Photosynthesis, the basis of life as it produces oxygen that many organisms need, is often seen as the general equation CO2+H2O+lightC6H12O6+O2, yielding glucose and oxygen as products. However, when the process is further broken down, photosynthesis can be divided into two reactions: light-dependent and light-independent. In addition, because photosynthesis is an endergonic reaction, the process will be slow to happen due to the fact that the products have more energy than the reactants. Furthermore, before glucose and oxygen can be produced, the light-dependent reaction must occur first. In this reaction light strikes the chloroplast causing a series of reactions, such as water splitting, the production of ATP, and NADPH is produced as an end result. After this occurs, the light-independent reaction occurs, starting with ATP and NADPH to reduce carbon dioxide to sugar. Carbon dioxide is then broken and carbon enters the cycle to leave as sugar, while the ATP generates energy for the reaction and NADPH adds electrons to form the sugar. In the end, glucose is made after several turns of the Calvin cycle. Overall, both the cycles work together in order to form sugar and oxygen that is essential to many living
Photosynthesis is a process that plans protistans and some bacteria, use energy from the sun to create sugar. Cellular respiration turns into ATP which is fuel used by all living things. The transformation of sunlight energy into chemical energy, also goes along with the same process as green pigment chlorophyll. The photosynthetic process mostly uses water and releases the oxygen that is mandatory for us humans must have to live.
And the light independent happens to make atp used to make the glucose. Atp is very important since cells use it for functions. however, with photosynthesis the cell respiration and photosynthesis chloroplast absorb the energy from sunlight and build sugras, then the mitochondria will release the chemical energy to make atp. the cell respiration starts with 3 carbon molecules they enter cell respiration in mitochondria, and the energy carrying molecules transfer energy to electron transport. so next the energy carrying molecule which atp molecules are produced. last heat and water are released as waste
We first learned about the process of photosynthesis. During photosynthesis, plants use the energy of light to produce glucose (their food). Photosynthesis only occurs for plant cells. The equation of photosynthesis is 6CO2+6H20+light energy=C6H1206+602. The chloroplasts have many parts. There is the thylakoids, granum, and stroma. The thylakoids have chlorophyll, which attracts the light energy. The granum is basically stacked thylakoids. In the chloroplasts, and in photosynthesis,
Autotrophs make their own food, by using the energy of the sun to make sugars from carbon dioxide and water. Heterotrophs depend on photosynthesis to consume carbon dioxide and then produce oxygen (respiration). Oxygen and an energy source create ATP, which powers cells. All life ultimately depends on photosynthesis, whether directly or indirectly. . Light is the most important component that affects photosynthesis, because it provides the energy necessary for driving the reaction. Without light, plants cannot create ATP or NADPH, which is how the plant creates sugars to feed itself, therefore causing it to die. In the oxidation and reduction process, sunlight is the energy source that moves electrons from oxygen to carbon.
Plant Cells help us in many ways.Plant Cells provide oxygen for us to breath. They make oxygen for us from a process called photosynthesis. Then your cells perform cellular respiration to make ATP. Photosynthesis and Cellular respiration are connected through an important relationship. Their formulas are the exact opposite. Cellular respiration formula is C6H12O6 + 6O2 → 6CO2 + 6H2O and photosynthesis is 6CO2 + 6H2O → C6H12O6+ 6O2.Photosynthesis makes glucose which then is turned back into carbon dioxide.In photosynthesis water is being broken down and in cellular respiration water is being combined with hydrogen to form water. The released oxygen is for cellular respiration. We breath the oxygen and the oxygen goes through our blood and cells. Photosynthesis happens everyday. Photosynthesis starts with the sun. It needs light to happen in the chlorophyll. The light is absorbed by the cell and starts the photosynthesis process. They then produce glucose from carbon dioxide and water. The glucose can be converted into pyruvate which releases ATP. Photosynthesis takes place in the chlorophyll. Chlorophyll is this green pigment inside the plant cell. It is a complex molecule. There are several modifications among
Introduction: Photosynthesis is a multistep process used by plants and certain algae to synthesize simple organic molecules from carbon dioxide and water. Energy from the sunlight is captured and stored in the form of chemical bonds in carbohydrate molecules. This highly regulated process provides the basic energy source for virtually all organisms. Oxygen is also produced from this process, which is an extremely important element on which most organisms depend. The general equation for photosynthesis is: 2H2O + CO2 + Light CH2O + O2 + H2O
Photosynthesis uses carbon dioxide and water and produces glucose. Photosynthesis provides the inputs for cellular respiration. Unlike cellular respiration which has three stages, photosynthesis has only two main stages, light reactions and the calvin cycle. The light reactions stage uses two different photosystems: water-splitting and NADPH-producing. These photosystems contain hundreds of pigment molecules such as chlorophyll a and b, and carotenoids. These pigments are very important for absorbing and reflecting light for the light reactions. The main fucnction of this first stage is to generate ATP and NADPH for the calvin cycle. The ATP and NADPH are used up along side carbon dioxide molecules to form an energy-rich sugar labeled G3P. G3P molecules are what are used to contrsuct glucose as well as other organic molecules. Carbon dioxide is essential for photosynthesis. Some plants are not able to receive the appropriate amount of carbon dioxide and therefore suffer as a result. However, some planst such a C4 and CAM plants have made evolutionary adaptations that allow the plant to still perform photosynthesis and survive on minimal amounts of carbon dioxide. These evolutionary adaptations also help to reduce water
The next part of photosynthesis is the light independent reactions. This part of photosynthesis relies on the ATP and NADPH that the light dependent reactions produce. First, the enzyme rubisco “fixes” carbon dioxide by attaching it to five-carbon RuBP. The carbons then split into three-carbon molecules of PGA. The PGA that is created is given a phosphate group from ATP and a hydrogen and electron from NADPH. This creates twelve PGAL. Two of these PGAL molecules are able to rearrange and create
