　　Photosynthesis光合作用

　　Photosynthesis nutrient chlorophyll vein carbondioxide二氧化碳

　　All living things need food and energy to survive. The food-making and energy process for plants to survive is called photosynthesis. Plants make food and produce oxygen through photosynthesis. The process is complex but with the sun, water, nutrients from the soil, oxygen, and chlorophyll, a plant makes its own food in order to survive.

　　任何生物都需要食物和能量來生存。植物制造用于生存的養料和能量的方式稱為光合作用。植物通過光合作用生成養料和氧氣。這個過程很復雜，但是通過陽光、水分、土壤里的養料、氧氣和葉綠素，植物能夠自養生存。

　　Chlorophyll is a green chemical inside a plant that allows plants to use the Sun's energy to make food. Without chlorophyll a green plant would not be able to survive.

　　葉綠素是植物內一種綠色的化合物，它能將太陽能轉化為養分。沒有葉綠素，綠色植物無法生存。

　　The following are the steps in photosynthesis:以下是光合作用的步驟：

　　1. The sunlight is absorbed through a plant by its leaves, or other green parts.

　　1、植物通過葉子或其他綠色部分來吸收太陽光。

　　2. The water and nutrients from the soil are absorbed through the roots of the plant.

　　2、植物通過根吸收土壤中的水分和養料。

　　3. The chlorophyll inside the plant's leaves traps the energy from the sunlight.

　　3、植物葉內的葉綠素將太陽光的能量鎖住。

　　4. Carbon dioxide in the air enters through the leaves of the plants. (Carbon dioxide is carbon and oxygen combined.)

　　4、植物通過葉子吸收空氣中的二氧化碳（二氧化碳是一種碳氧化合物）。

　　5. Inside the chlorophyll there are chloroplasts which contain water and the carbon dioxide from the air.

　　5、葉綠素中含有葉綠體，葉綠體中含有水分和來自空氣中的二氧化碳。

　　6. The chloroplasts are like tiny manufacturing plants. The water and carbon dioxide from the air combine to make sugar and water. Basically, it is the food for the plant to survive and grow.

　　6、葉綠體就像一個小小的制造車間。水和空氣中的二氧化碳結合生成糖和水。基本上，這就是用于植物生存和生長的食物。

　　7. Sugar is then made and released into the veins of the leaf and it spreads throughout the rest of the plant.

　　7、生成的糖被釋放到葉脈中，并分布到植物的其他部分。

　　8. The oxygen the plant has made is then released into the air.

　　8、而植物生成的氧氣被釋放到了空氣中。

　　The entire process is called photosynthesis, and without it people and other animals would not be able to live and grow. This is the reason it is important for the survival of trees and plants. They give off oxygen which help people and other animals to breathe.

　　The plants also give people and animals food to eat. The food could be the different kinds of fruit or the many varieties of vegetables from apples and oranges to green beans and peas.

　　整個過程稱之為光合作用。沒有光合作用，人類和動物將無法生存。這也是樹和植物存在的重大意義。因為植物能產生人和動物呼吸需要的氧氣。

　　植物也能作為人和動物的食物。這些食物可以是各種各樣的水果或蔬菜，可以是蘋果、橘子，也可以是青豆和豌豆。

　　When people and animals eat this food from the plants it also gives them the energy to live and grow. Without plants, animals and people would not be able to survive.

　　當人們和動物吃了這些植物后，這些植物將轉化為用于生存的能量。沒有植物，動物和人類都將無法生存。

　　During the fall in certain parts of the world photosynthesis no longer takes place. When this happens the leaves begin to turn different colors. The leaves may turn yellow, orange or maybe even red, or a combination of those colors. Surprisingly, these colors are the original colors of the leaves.

　　在秋天的時候，一些地方將無法進行光合作用。因為到了秋天，葉子開始變換顏色。葉子可能會變成黃色、橘色甚至是紅色或者是這些顏色的混合。神奇的是，這些顏色才是葉子本身的顏色。

　　In the spring and summer there is too much green color from the chlorophyll for the leaves to be seen as their original colors. As the temperature drops, though, the leaves of trees, other than evergreens, stop making the chlorophyll. The chlorophyll begins to vanish and the leaves begin to change colors.

　　在春天和夏天的時候，太多的葉綠素使葉子幾乎看不出它們原本的顏色。然而，隨著溫度下降，除了常綠植物之外的植物都將停止產生葉綠素。而葉綠素也逐漸消失，于是葉子開始變為原本的顏色。

　　In summary, photosynthesis is the food-making and energy process for plants to survive. A plant's leaves contain chlorophyll which is a green chemical inside a plant that allows plants to use the Sun's energy to make food. Chloroplast inside the chlorophyll contain water and the carbon dioxide from the air to make the food for the plant to survive. Without photosynthesis, the plants would not be able to live and grow.

　　本課小結：光合作用是植物制造養料和能量的生存方式。植物的葉子中含有一種綠色化合物成為葉綠素，它能讓植物利用太陽能來生成養料、而葉綠體是葉綠素內一種能同化水喝空氣中的二氧化碳并制造植物生存的養料的物質。沒有光合作用，植物將無法生長和生存。
