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

缺乏大核或膜 Stentor 部分只能存活很短。

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

切片必须至少包含部分大核一块膜。

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

大核控制非生殖能，如进食、运动消化， 而微核是繁殖所必需。

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.

如果膜大核都存在，那么即使是小于蓝展螺百分之一大小微小碎片也可以通过这种方式自我重组。
