Animal and plant cells have cell membranes.

动物和植物细胞都具有细胞膜。

Plant cells make energy a different way.

植物细胞是用別种方式得到能量。

Most cells are eukaryotic — animal cells, plant cells, and fungi, etc.

大多数细胞是真核生物——动物细胞、植物细胞和真菌等。

Both plant cells and animal cells are surrounded by a cell membrane.

动植物的细胞都是被一层细胞膜包裹。

Chlorophyll enables plant cells to absorb light so it can be used in photosynthesis.

叶绿素使植物细胞能够吸收光线，以进行光合作用。

Plant cells have an extra layer called a cell wall that surrounds the membrane.

植物细胞膜外还有额外的一层，即所谓的“细胞壁”。

They're activated when they're exposed to sunlight after a plant's cells are broken open.

但是它们会在植物细胞受损并暴露在阳光下时被激活。

Plant cells also contain chloroplasts which are filled with a chemical called chlorophyll.

植物细胞还包含叶绿体，里面充满了一种叫做叶绿素的化学物质。

Chloroplasts are found only in plant cells and contain chlorophyll.

叶绿体仅存在于植物细胞内，而且含有叶绿素。

Only plant cells have a cell wall, which is made of rigid cellulose that gives the plant structure.

但只有植物细胞有细胞壁，它是由硬质纤维素组成，能形成植物的支撑架构。

So while an animal cell has a membrane, a plant cell has a membrane and a cell wall.

动物细胞有细胞膜，植物细胞有细胞膜和细胞壁。

He found that the bacteria placed a piece of their genetic material, or DNA inside the plant cells.

他发现这种细菌将少量基因物质植入植物细胞内。

For now, we will be dealing with two types of cells: plant cells and animal cells.

现在，我们将讨论两种类型的细胞：植物细胞和动物细胞。

But plant cells don't have that choice because of their cell walls.

但植物细胞没有这种选择，因为它们的细胞壁。

Simple plant cells may have only one or two chloroplasts in them.

简单的植物细胞可能仅有一个或两个叶绿体。

As the bacteria continue to feed and multiply, they start to kill off the plant cells.

随着细菌不断得到滋养和繁殖，它们开始杀死植株细胞。

During this process, sunlight hits structures within a plant's cells called chloroplasts, which are packed with chlorophyll pigments.

在光合作用中，太阳光照射在植物细胞里一些叫做叶绿体的结构上，而这些叶绿体中含有大量的叶绿素色素。

Within the plant cell, the water is oxidized. This transforms the water into oxygen and the carbon dioxide into glucose.

在植物细胞内，水氧化并转化为氧气，而二氧化碳转化为葡萄糖。

A plant cell usually has one large vacuole, whereas an animal cell may have several smaller ones, called vesicles.

植物细胞通常有一个大液泡，而动物细胞可能会有许多较小的液泡，成为囊泡。

Instead of pinching off and saying goodbye, plant cells are forever locked in next to their parent cells.

植物细胞永远被锁在它们的亲本细胞旁边，而不是被掐掉、就此离去。
