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

缺乏大核或的 Stentor 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.

切片必须至少包大核一块。

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

大核控制非生殖功能，如进食、运动消化， 而微核是繁殖所必需的。

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.

如果大核都存在，那么即使是小于蓝展螺的百之一大小的微小碎片也可以通过这种方式自我重组。
