What is photosynthesis in short answer?
A chemical process that occurs in plants, algae, and some types of bacteria, when they are exposed to sunlight. During photosynthesis, water and carbon dioxide combine to form carbohydrates (sugars) and give off oxygen. photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.Photosynthesis is the process that plants go through to make food by using sunlight and chlorophyll to turn water and carbon dioxide into nutrients.The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.Unfortunately, getting humans to photosynthesize sunlight is next to impossible. Unlike the tiny pea aphid, the hornet or the slug, humans demand an enormous amount of energy to survive.Photosynthesis (/ˌfoʊtəˈsɪnθəsɪs/ FOH-tə-SINTH-ə-sis) is a system of biological processes by which photopigment-bearing autotrophic organisms, such as most plants, algae and cyanobacteria, convert light energy — typically from sunlight — into the chemical energy necessary to fuel their metabolism.
What is photosynthesis class three?
Photosynthesis is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.Photosynthesis is the process through which plants use light energy, carbon dioxide, and water to produce food (sugar) and oxygen.Green plants capture solar energy & convert it into chemical energy – by photosynthesis. CO2 & H2O ———-→ Carbohydrates & O2 Carbohydrates —-→ lipids, nucleic acids, proteins, etc. These organic molecules – elaborated in leaves, stem, roots, fruits, seeds & other tissues.Photosynthesis is a process in which plants use sunlight, water and carbon dioxide to create oxygen and energy in the form of sugar. This process forms the basis of lives and many lives on earth depend on this process. The word ‘Photo’ in Greek stands for light and synthesis stands for ‘combining together.It is the primary source of all food on earth. It helps convert solar energy into organic matter. It is also responsible for the release of molecular oxygen into the atmosphere by green plants. This evolved oxygen is consumed by other living organisms which helps maintain the levels of atmospheric oxygen.
What are photosynthesis class 10 notes?
Photosynthesis is a vital anabolic process used by plants, algae, and some bacteria to convert light energy into chemical energy. During this process, these organisms, known as autotrophs, use sunlight, water, and carbon dioxide to create glucose (sugar), which serves as their food, and release oxygen as a byproduct. Chlorophyll is the green pigment found in almost all types of plants. It’s also what gives plants their green color. Chlorophyll is located inside chloroplasts, or the part of the plant cell where photosynthesis happens.Photosynthesis is how plants, algae and some bacteria turn light into chemical energy stored in glucose, which is a type of sugar. The process creates oxygen and is the basis of the food chain. Chloroplast is an organelle you find in the cells of green plants and algae.Green plants carry out ‘photosynthesis’, a physico-chemical process by which they use light energy to drive the synthesis of organic compounds. Ultimately, all living forms on earth depend on sunlight for energy. The use of energy from sunlight by plants doing photosynthesis is the basis of life on earth.Chlorophyll is a pigment present in all green plants and a few other organisms. It is required for photosynthesis, which is the process by which light energy is converted into chemical energy. The chlorophyll pigment is responsible for the green colouration in plants.
What is photosynthesis for class 4?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. Photosynthesis is the process of turning sunlight, carbon dioxide, and water into glucose and oxygen. All plants carry out photosynthesis. This is how they make food. The glucose is a kind of sugar that holds chemical potential energy.Based on our learnings so far, we have found that sunlight, water, chlorophyll and carbon dioxide are essential for the synthesis of food in plants. This process by which plants prepare food in the presence of sunlight and chlorophyll is called photosynthesis. A leaf is the primary site for photosynthesis.Dutch-born British physician and scientist Jan Ingenhousz is best known for the discovery of the process of photosynthesis, by which green plants in sunlight absorb carbon dioxide and release oxygen.Photosynthesis is the process by which plants use light energy from the sun to convert carbon dioxide and water into sugar. The by-product, or waste gas of this process is oxygen.
Why is it called photosynthesis?
The word “photosynthesis” is derived from the Greek words phōs (pronounced: “fos”) and σύνθεσις (pronounced: “synthesis“)Phōs means “light” and σύνθεσις means, “combining together. This means “combining together with the help of light. Photosynthesis also applies to other organisms besides green plants. Photosynthesis is incredibly important – in fact, without it, life on Earth as we know it could not exist. It is the mechanism by which solar energy is converted to chemical energy in the forms of sugars, starches and fats.Plants, algae, and cyanobacteria, known as photoautotrophs, are the only organisms capable of performing photosynthesis. Heterotrophs, unable to produce their own food, rely on the carbohydrates produced by photosynthetic organisms for their energy needs.Plants make their food using sunlight, water, carbon dioxide and nutrients and minerals from the soil. This process is called photosynthesis.Complete answer: Photosynthesis is important to all life on earth as it is the number one source for releasing oxygen directly into the atmosphere. It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces.The light-dependent stage of photosynthesis The first stage of photosynthesisThe process by which plants use sunlight to convert carbon dioxide and water into carbohydrates and oxygen. It involves the capture and conversion of sunlight into chemical energy.
What are photosynthesis class 6 notes?
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Photosynthesis takes place in two stages: light dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.Green plants get the energy to grow from the sun through the process of photosynthesis. This leaf likely fell off a tree in the fall once the trees paused photosynthesis for the winter and sank to the bottom of the lake, where it was buried.In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.During photosynthesis, energy from sunlight is harvested and used to drive the synthesis of glucose from CO2 and H2O. By converting the energy of sunlight to a usable form of potential chemical energy, photosynthesis is the ultimate source of metabolic energy for all biological systems.
