光合作用是植物用来制造食物的一种特殊能力。就像我们需要食物来获得能量一样，植物也需要能量来生长和活动。植物通过光合作用，利用阳光、空气和水制造出食物和氧气。
Photosynthesis is a special ability that plants have to make their own food. Just like how we need food to get energy, plants need energy to grow and do their things. They use a process called photosynthesis to make food and oxygen using sunlight, air, and water.
植物的叶子中有一些小东西叫叶绿体，就像是它们的小厨房一样。当阳光照在叶子上时，叶绿体会抓住阳光，并使用它的力量将水和空气中的二氧化碳变成食物。这个食物叫做葡萄糖，它是一种能量，就像是植物的能量饭菜。
Inside the leaves of plants, there are tiny things called chloroplasts, like their little kitchens. When the sunlight shines on the leaves, the chloroplasts catch the sunlight and use its power to turn water and carbon dioxide from the air into food. This food is called glucose, and it's a kind of energy, like a meal for the plant.
在光合作用过程中，植物不仅制造食物，还产生氧气。氧气是我们呼吸的空气中的一部分，所以植物帮助我们保持健康。
During photosynthesis, plants not only make food but also produce oxygen. Oxygen is part of the air we breathe, so plants help keep us healthy.
光合作用是一个非常重要的过程，它让植物成长并且保持了地球的生态平衡。而且，植物制造的食物也是其他动物的食物，所以它在自然界中扮演着重要的角色。
Photosynthesis is a really important process that helps plants grow and keeps the balance of nature on Earth. Plus, the food plants make becomes food for other animals, so it plays a big role in the natural world.
