植物如何自己制造食物？

Plants produce glucose — a simple sugar — through a process called photosynthesis, which literally means 'putting together with light'.
They absorb sunlight using chlorophyll, a green pigment found mainly in leaves, and convert light energy into chemical energy.
Carbon dioxide enters the plant through tiny pores called stomata, while water travels upward from roots through vascular tissue.
Inside leaf cells, sunlight energizes electrons that help combine CO₂ and H₂O into glucose and oxygen.
The overall chemical equation is: 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂.
Oxygen, a vital byproduct, is released into the air — meaning every breath you take depends partly on this process.
Without photosynthesis, there would be almost no oxygen or organic food chains on Earth.
Some bacteria perform similar processes, but only plants, algae, and cyanobacteria do it on a global scale.

The overall chemical equation is: 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂. 总反应式为：6CO₂ + 6H₂O + 光 → C₆H₁₂O₆ + 6O₂。
Without photosynthesis, there would be almost no oxygen or organic food chains on Earth. 若无光合作用，地球将几乎不存在氧气或有机食物链。
Inside leaf cells, sunlight energizes electrons that help combine CO₂ and H₂O into glucose and oxygen. 在叶细胞内，阳光激发电子，促使二氧化碳和水结合生成葡萄糖和氧气。

这篇中文题目最接近哪一句？植物如何自己制造食物？一次学校运动会的通知一份超市购物清单

课文第一句的意思更接近？植物通过光合作用——字面意思是“利用光合成”——制造葡萄糖（一种单糖）。今天学校放假了。请把窗户打开。

这一课主要在讲什么？（看英文标题） How Do Plants Make Their Own Food? How to cook noodles A maths worksheet

The overall chemical equation is: 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂.

The overall chemical equation is: 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂.

第一版：录下来、回听、再听标准音。系统打分以后再加。

用今天的表达，自己说一句。
