photosynthesis
Meaning: The process by which green plants and certain other organisms convert light energy, carbon dioxide, and water into glucose and oxygen.
Photosynthesis is the foundation of almost all life on Earth, providing the oxygen we breathe and forming the base of food chains. It occurs primarily in the chloroplasts of plant cells, using the green pigment chlorophyll to capture sunlight. Artificial photosynthesis is an active area of research aimed at producing clean fuels.
Examples
- Photosynthesis is responsible for producing the oxygen that sustains most life on Earth. 光合作用负责产生维持地球上大多数生命的氧气。La fotosíntesis es responsable de producir el oxígeno que sustenta la mayor parte de la vida en la Tierra.光合成は、地球上のほとんどの生命を支える酸素の生成を担っている。광합성은 지구상 대부분의 생명을 유지하는 산소를 생산하는 역할을 한다.
- The rate of photosynthesis increases with light intensity up to a certain saturation point. 光合作用的速率随光照强度的增加而提高,直到达到某个饱和点。La tasa de fotosíntesis aumenta con la intensidad luminosa hasta alcanzar un determinado punto de saturación.光合成の速度は光の強度に比例して上昇するが、ある飽和点に達すると頭打ちになる。광합성 속도는 빛의 세기에 비례하여 증가하지만 일정 포화점에 도달하면 더 이상 증가하지 않는다.
- Researchers are developing artificial photosynthesis systems that could generate hydrogen fuel from sunlight and water. 研究人员正在开发人工光合作用系统,可以利用阳光和水产生氢燃料。Los investigadores están desarrollando sistemas de fotosíntesis artificial capaces de generar combustible de hidrógeno a partir de luz solar y agua.研究者たちは、太陽光と水から水素燃料を生成できる人工光合成システムの開発を進めている。연구자들은 태양광과 물로부터 수소 연료를 생성할 수 있는 인공 광합성 시스템을 개발하고 있다.
