"Photosynthesise" Natural Recordings by Native Speakers
To undergo photosynthesis, the process by which plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose, a type of sugar, and release oxygen as a byproduct.
Photostabilisers are chemicals that are added to materials, such as paints, coatings, adhesives, and plastics, to protect them from the effects of sunlight and ultraviolet (UV) radiation. Their purpose is to prevent or slow down the degradation of these materials caused by the interaction with sunlight, heat, or other environmental factors.Photostabilisers work by absorbing or scattering UV radiation, thereby reducing the amount of energy that is available to cause chemical reactions in the material. This helps to prevent the breakdown or degradation of the material, which can lead to changes in its appearance, texture, or performance.Common examples of photostabilisers include:<em> UV absorbers (such as benzotriazoles and benzophenones)</em> UV reflectors (such as pigments and fillers)<em> Quenchers (substances that deactivate free radicals and other reactive intermediates)</em> Antioxidants (substances that prevent the formation of reactive oxygen species)Photostabilisers are widely used in various industries, including:<em> Coatings: painting, enamels, varnishes, and inks</em> Plastics: injection-molded parts, film, cosmetics, and personal care products<em> Textiles: fabrics, dyes, and finishes</em> Adhesives: caulks, sealants, and bonding agentsBy using photostabilisers, manufacturers can extend the lifespan of materials and reduce the risk of premature degradation, which can lead to economic losses and environmental problems.
Chemicals that slow down the breakdown of photographic emulsions by light and resistance to fading, allowing permanent images to be stored.
A photostat or Xerox is a copy of a document made by photography, typically an exact reproduction of a written or printed page. It is essentially a photographic copy of a document.
Photostatic refers to something that is exact or completely accurate, often in relation to a photograph or other visual representation. It can also imply a sense of indisputable or conclusive evidence, often used to describe a situation where the facts are clear and cannot be disputed.
Photosynthate refers to a chemical produced by green plants, algae, and some bacteria during photosynthesis, the process by which they convert light energy into chemical energy. It is a compound that contains energy produced by the synthesis of glucose from carbon dioxide and water in the presence of sunlight. In other words, photosynthate is the end product of photosynthesis, which is used as energy by the plant itself and also made available to other organisms in the ecosystem through the process of decomposition or herbivory (e.g., consumption by animals).
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of organic compounds, such as glucose. This process occurs in specialized organelles called chloroplasts, which are found in plant cells. Photosynthesis involves the conversion of carbon dioxide and water into glucose and oxygen through a series of light-dependent and light-independent reactions.
Photosynthesis is the process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of organic compounds, such as glucose. This process occurs in specialized organelles called chloroplasts and requires water, carbon dioxide, and sunlight to produce oxygen and glucose.
The process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of organic compounds, such as glucose, that are used to fuel the organism's activities and growth.
To produce carbon dioxide and oxygen as byproducts in the process of converting sunlight, carbon dioxide, and water into glucose, using chlorophyll.
Produced or formed through photosynthesis, a process in which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose.
Producing offspring that grow and thrive using sunlight energy, especially in green plants and some other organisms.
In biology, a photosystem is a large, light-absorbing molecule complex that plays a central role in the process of photosynthesis. It is the site where light energy is absorbed and converted into chemical energy.Photosystems are found in the thylakoid membranes of chloroplasts in plant cells and are composed of proteins and pigments, including chlorophyll and other accessory pigments. They are responsible for driving the transfer of electrons during photosynthesis, which ultimately leads to the production of ATP and NADPH, the energy carriers that power the conversion of CO2 into glucose.There are two main types of photosystems: Photosystem II (PSII) and Photosystem I (PSI). PSII is responsible for absorbing light energy and transferring electrons to a special molecule called plastoquinone. PSI, on the other hand, uses the energy from PSII to convert light energy into a high-energy molecule called ATP.In summary, photosystems are complex molecular structures that are essential for the process of photosynthesis, converting light energy into chemical energy that can be used by plants to grow and thrive.
Phototactism (or photoactism) is a rare term referring to a stimulus-response reaction to light. It can be seen as a form of phototropism, a phenomenon where an organism grows or moves towards or away from light. However, phototactism specifically describes a nervous response wherein an animal senses and reacts to light using its skin or other bodily tissues.For example, some invertebrates, such as sea creatures and certain worms, exhibit phototactic responses. When light is applied to their sensitive skin, they move towards (positive phototactism) or away (negative phototactism) from the light source in a reflex reaction. This is different from phototropism, which involves the actual growth towards or away from light sources, rather than just a reflex movement.
