There's not a single, universally accepted term for when cytoplasm begins to separate. The specific terminology depends on the context and the reason for the separation. Here are some possibilities:

General terms:

* Cytoplasmic fragmentation: This term is broad and can describe any process that leads to the breaking down of cytoplasm into smaller pieces.

* Cytoplasmic cleavage: This term is often used in the context of cell division (mitosis or meiosis) where the cytoplasm divides to form two daughter cells.

Specific terms:

* Apoptosis: This is a programmed cell death process where the cell actively breaks down its cytoplasm and organelles, often leading to the formation of apoptotic bodies.

* Necrosis: This is a type of cell death that involves uncontrolled cell lysis (bursting). This process can lead to the release of the cytoplasm into the surrounding environment.

* Cytoplasmic streaming: This is a phenomenon in some cells where the cytoplasm flows in a specific direction, potentially leading to localized separation of cytoplasmic components.

* Cytoplasmic segregation: This term describes the uneven distribution of cytoplasmic components during cell division, which can be seen in some specialized cell types.

To understand the specific process you're interested in, please provide more context. For example:

* What type of cell are you considering?

* What is the cause of the cytoplasmic separation?

* What is the outcome of the separation?

Providing this information will help to determine the most accurate term for the process you are referring to.
