What it is Filled
The material within a living cell enclosed by the cell membrane, excluding the nucleus in eukaryotes: the cytosol, a water-based solution of ions, small molecules and proteins, together with the organelles, cytoskeleton and inclusions suspended in it; the site of most metabolism, protein synthesis and transport within the cell.
Why it exists Filled
Let an agent explain the cytoplasm and its components, distinguish cytoplasm from cytosol, nucleus and specialised regions, relay facts from cell biology references, and route detailed biochemical questions to the relevant entries.
Distinguishing features Filled
- Bounded by the cell membrane
- Excludes the nucleus in eukaryotes
- Contains cytosol, organelles and cytoskeleton
- Crowded, gel-like and dynamic
What robots and AI may and may not do Filled
Must not
- Confuse cytoplasm with cytosol or with the contents of the nucleus.
- Present simplified textbook models as complete descriptions of the cell.
- Use the term to lend false scientific weight to health products.
Only with a human decision
- Use of human cells or tissue in research.
May
- Explain the composition of cytoplasm and its role in cell function.
- Describe how cytoplasm differs between prokaryotic and eukaryotic cells.
Moral aspects Filled
- Accurate basic biology underpins trust in medicine and science teaching.
- Cell research uses material from donors who must consent.

- Researchers
- Cell and tissue donors
Owners Filled

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.cytoplasm
- Wikidata: Q79899 (https://www.wikidata.org/wiki/Q79899)
- Gene Ontology: GO:0005737 cytoplasm
- UBERON or CL terms: per context cell ontology
Direct properties required Filled
- water content: about 70-80 percent
- pH: about 7.2 pH - cytosol
- fraction of cell volume: about 50-80 percent - varies by cell type
Recognition required Filled
- Everything inside the membrane except the nucleus
- Cytosol plus organelles and cytoskeleton
- The nucleoplasm and the extracellular matrix are outside it
- Not visible to the eye; under the microscope a translucent gel with organelles and granules.
Capabilities and actions required Filled
- explain composition and organisation
- distinguish cytoplasm from cytosol and nucleoplasm
- explain roles in metabolism and transport
- route to organelle and pathway entries
Hazards and failure modes required Filled
- Confusing cytoplasm with cytosol
- Treating it as a uniform fluid
- Outdated textbook simplifications
Standards and interfaces required Filled
- Gene Ontology and cell ontology definitions
Context of use required Filled
- Not for anything; the internal medium of the cell.
- cytosol
- organelles such as mitochondria and endoplasmic reticulum
- cytoskeleton
- inclusions such as glycogen and lipid droplets
- specialised regions such as the cell cortex, sarcoplasm and ooplasm
- prokaryotic cytoplasm without membrane-bound organelles
Sources Filled

- Wikipedia: Cytoplasm - general description of the item
Open questions
- Should cytosol be a separate entry?
- How should ontology terms be linked?
- The registry entry has merged aliases for specialised regions; should they be split off?
