cnidocytes vs nematocysts
Cnidocyte刺丝囊声音太不同,but they are not so. Therefore, understanding the actual meaning of these terms would be of real importance. The facts about these structures are of great interest, and this article explores those to study whether both these are the same or two different types. Therefore, the presented information would only be beneficial for the reader than not.
什么是cnidocyte?
CNIDOCTES也称为线虫细胞或CNIDOBLASTS。这些是在腔植物或门的成员中唯一发现的一种有毒细胞:cnidaria。值得注意的是,Cnidarians可以通过捕食以大鱼为食。这种惊人的能力是由于存在cnidocytes或线虫细胞。确切的事实原因是每个cnidocyte中称为线虫细胞的细胞器存在。下一段中描述了有关线虫囊的结构和其他重要特征。这些有毒细胞对于捍卫其菌落和觅食方面的卵巢非常重要。他们的掠食能力应受到高度评价,主要是因为这些cnidarians缺乏内部骨骼,并且大多是无柄的。但是,CNIDOCTES是一次使用单元,一次发射后不能使用。此外,必须避免使用失误和自我刺激。 Therefore, a regulatory mechanism of firing is present. According to the structure of nematocytes, there are more than 30 types, but they all fall under four main types. They four types have different strategies to attack the prey including piercing, sticking, wrapping, and other methods of firing. Therefore, the importance of cnidocytes for the cnidarians cannot be compared with other organs in the extremely competitive ecosystem.
什么是线虫囊?
线虫囊是在鞘岩的线虫内发现的专门细胞器,如上所述。线虫囊是带有灯泡形状的胶囊,其中包含一个尖锐的倒钩,该倒钩通过盘绕螺纹连接到胶囊的底部。在胶囊外面,有一个称为cnidocil的小型头发的结构,这是用毒药发射倒钩的扳机。当激活扳机时,具有毒药的倒钩在超速上达到目标(主要是生物体或猎物的皮肤),每秒加速5 41,000,000米。到达目标生物的平均时间是通过最近的研究计算的,仅700纳秒。数百万这些黑藻菌一次被整个腔植物(例如水母)的菌落一次激活,即使是大尺寸的猎物也很容易被禁用。当生物体通过cnidarians的殖民地徘徊时,无形的CNIDOCIL触发器被触摸,并突然造成毒物攻击导致死亡。通常,毒素被鉴定为神经毒素,会使猎物动物的神经系统瘫痪。
What is the difference between Cnidocytes and Nematocysts? • Cnidocytes are a special type of cells in cnidarians, whereas nematocysts are specialized sub-cellular organelles found inside cnidocytes. •CNIDOCTES有四种主要类型,在其中一种类型中发现了线虫细胞。 |

是否有steNoteles/渗透剂,Desmonemes/Volvents,原始的Isorhiza/Sterereoline Glutinant和Holotrichous Isorhiza的/链肽素麸质的通用名称?我的意思是所有捕获猎物并用于翻滚/运动的细胞?
