chloroplast

chloroplast的音标是["kl:ərəu, spɔːltæst]，基本翻译是叶绿体。速记技巧是利用词根记忆，可以将chloro-和-plast分别记忆，前者意为“绿色的”，后者意为“形成…的物质”。

Chloroplast这个词源自希腊语，其中“chloros”表示“绿色”或“植物”，“plastos”表示“塑造”。Chloroplast是植物细胞中的一个细胞器，主要负责光合作用。

变化形式：

1. chlorophyll（叶绿素）：这个词由“chloros”和“phyllon”组成，表示绿色的叶物质。

2. photosynthesis（光合作用）：这个词由“photo”（光）和“synthesis”（合成）组成，表示通过光合作用将光能转化为化学能的过程。

1. chloroform（氯仿）：一种有机化合物，化学式为CHCl3，是一种常用的麻醉剂。

2. chlorine（氯）：一种非金属元素，化学符号为Cl，是氯气的化学名称。

3. chlorine dioxide（二氧化氯）：一种强氧化剂和杀菌剂，化学式为ClO2。

4. chlorophyllin（叶绿素盐）：叶绿素的盐类，通常用于食品和药品中。

5. chloroplastid（类囊体）：一种存在于叶绿体中的细胞器，是进行光合作用的主要场所。

6. chloroplast biogenesis（叶绿体发育）：描述叶绿体形成的生物学过程。

7. chloroplast movement（叶绿体移动）：描述叶绿体在细胞内移动的现象。

英文小作文：

Chloroplasts are essential organelles in plants that play a crucial role in photosynthesis, the process by which plants convert sunlight into chemical energy. Without chloroplasts, plants would be unable to survive in the harsh environment of the planet.

Chloroplasts are tiny structures within plant cells that contain the enzymes needed for photosynthesis. They are surrounded by a double membrane and contain pigments that absorb sunlight and convert it into chemical energy. Through chloroplasts, plants are able to convert sunlight into sugars, which are then used as a source of energy and nutrients for the plant itself and its surrounding environment.

Chloroplasts are also important for plant adaptation to environmental changes. For example, when plants experience changes in temperature, light, or humidity, they respond by moving their chloroplasts to different parts of the cell, allowing them to adapt to their new environment and continue to survive.

In conclusion, chloroplasts are essential for plant survival and adaptation to environmental changes. Understanding their structure and function is crucial for understanding how plants work and how we can use them to benefit our own lives and the environment around us.
