Name: | blastomere |

Synonyms: | blastomeres |
Definition: | Cell that arises during cleavage and is partially cleaved, and located at the blastodisc margin prior to collectively forming the yolk syncytial layer (YSL) in the midblastula. |

Name: | cleavage furrow |

Synonyms: | |
Definition: | The cleavage furrow is a plasma membrane invagination at the cell division site. The cleavage furrow begins as a shallow groove and eventually deepens to divide the cytoplasm. |

Name: | has fewer parts of type |
---|---|
Synonyms: | decreased number of, has decreased number of, has fewer physical parts of type |
Definition: | The bearer of this quality has_part < n AND has_part > 0 of the indicated entity type, where n is the normal amount for a comparable organism. Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly. |

Synonyms: | |
Definition: | Embryonic structure that is the dome of cytoplasm that segregates from the yolk toward the animal pole during and after the one cell-stage, and which undergoes cleavage. |
