This new growth also reinforces the cell wall by going against the grain of the existing wall.

这一生长促使对现有细胞壁纹理的抵触，因此也强化了细胞壁。

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。

UW solution will stabilize the cell walls.

UW溶液可以稳定细胞壁。

Staph saprophyticus has a thick peptidoglycan cell wall, which takes in purple dye when Gram stained - so this is a gram-positive bacteria.

腐生葡萄球菌具有一层较厚的细胞壁，由肽聚糖构成，这使它在革兰染色时呈现为紫色，因此它是革兰氏阳性细菌。

Cellulose is the main component of plants' cell walls, and you'll find most cellulose in those parts of plants that are not eaten by animals.

纤维素是植物细胞壁的主要组成成分，而且多数作物富含纤维素的部分都是家畜不食用的。

24. In fact, we can actually use the cell walls of filamentous fungi as a filter, even after the fungi are dead.

When the microbes die, their corpses, especially those cell walls, can stick around for a really long time, maybe even thousands of years.

当微生物死亡时， 它们的尸体， 尤其是那些细胞壁，可以存活很长时间， 甚至数千年。

Cell penetration is achieved using special polymer coatings, but to keep the cells healthy a team of researchers has identified several non-toxic compounds that work to allow entry and then seal the cell wall afterwards.

细胞渗透是使用特殊的聚合物涂层实现的， 但为了保持细胞健康， 一组研究人员已经确定了几种无毒化合物， 它们可以允许细胞进入， 然后封闭细胞壁。

Viruses called " phages, " which are basically chunks of genetic material wrapped in a protective protein, will pierce the cell wall of a bacterium and hijack its genetic machinery, turning the bacterium into a factory for making more viruses.

被称为“噬菌体”的病毒，基本上是包裹在保护性蛋白质中的大块遗传物质，它将穿透细菌的细胞壁，劫持其遗传机制，把细菌变成制造更多病毒的工厂。

There are also more unusual bacteria like mycoplasma pneumoniae, chlamydophila pneumoniae, and legionella pneumophila, which don't have a cell wall and are well known for causing an " atypical or walking pneumonia" because they often cause vague symptoms like fatigue.

还有一些更不寻常的细菌，如肺炎支原体、肺炎衣原体以及嗜肺军团菌，它们没有细胞壁，且因引起“非典型肺炎”而臭名昭着，因为它们通常会引起一些模糊的症状，如疲劳。

And if osmosis causes lots of movement of water into the cell, plant cells swell and become turgid; they have a strong cell wall, which prevents them from bursting, whereas animal cells don't have a cell wall, and so they burst.

如果渗透作用导致大量水分进入细胞，植物细胞就会膨胀，变得浮肿；它们有坚固的细胞壁，可以防止它们破裂，而动物细胞没有细胞壁，所以它们会破裂。
