Portions of Stentor lacking either macronucleus or cell membrane only survive for a short time.

缺乏或细胞膜的 Stentor 部分只能存活很短的时间。

The cut piece must contain at least part of the macronucleus and a piece of the cell membrane.

切至少包含部分一块细胞膜。

The macronucleus controls the non-reproductive cell functions, like eating, movement, and digestion and the micronucleus is necessary for reproduction.

控制非生殖细胞功能，如进食、运动消化， 而微是繁殖所需的。

Even a tiny fragment less than one-one hundredth the size of Stentor coeruleus can reconstitute itself in this way if both the cell membrane and the macronucleus are present.

如果细胞膜都存在，那么即使是小于蓝展螺的百分之一小的微小碎也可以通过这种方式自我重组。
