What energy is used in the process of photosynthesis?
light energy
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. 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.
What type of chemical reaction is photosynthesis?
endothermic reaction
Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves. Chlorophyll is found in chloroplasts in plant cells , particularly the palisade and spongy mesophyll cells .
What is the process called that changes water carbon dioxide and sunlight energy into sugar glucose?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Which process in photosynthesis uses energy from the sun?
light-dependent reactions
Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.
Does photosynthesis produce carbon dioxide?
Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
Which type of reaction is electrolysis of water?
Electrolysis of water is its decomposition to give hydrogen and oxygen gases due to the passage of an electric current.
What is the use of carbon dioxide in photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
How do water plants get carbon dioxide?
Terrestrial (land) plants use their roots to get water, they collect carbon dioxide through openings on their leaves called stomata, and sunlight is captured through chloroplasts within the plant.
How do plants obtain carbon dioxide and water?
Plants absorb water from the soil through the roots by Osmosis and They get Carbon dioxide from the air through the Stomata present on the leaves which facilitate for gaseous exchange.
Why do plants take up carbon dioxide during photosynthesis?
Plants extract the carbon dioxide from the air and use it in photosynthesis process to feed themselves. During this process, the plant combines carbon dioxide with water to allow the plant to extract what it needs for food. The plant uses sunlight as energy to perform this chemical reaction.
Which reaction takes place during photosynthesis?
series of reactions that take place during photosynthesis, where carbon dioxide and water from the atmosphere are converted into sugar. chemical element with the symbol C, which forms the basis of all known life. organism that eats meat. plants’ green pigment that is essential to photosynthesis.
How is oxygen liberated as a by-product of photosynthesis?
Oxygen is liberated as a by-product and light is considered as a major factor to complete the process of photosynthesis. Photosynthesis occurs when plants use light energy to convert carbon dioxide and water into glucose and oxygen.
What type of energy is used in photosynthesis?
During this stage, energy from the ATP and NADPH molecules is used to assemble carbohydrate molecules, like glucose, from carbon dioxide. Not all forms of photosynthesis are created equal, however. There are different types of photosynthesis, including C3 photosynthesis and C4 photosynthesis. C3 photosynthesis is used by the majority of plants.
How do herbivores obtain energy during photosynthesis?
Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores. During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.
