A double membrane structure enclosing an organelle, including two lipid bilayers and the region between them. In some cases, an organelle envelope may have more than two membranes. The outer, i.e. cytoplasm-facing in a cellular organelle, lipid bilayer of an organelle envelope. The outer, i.e. cytoplasm-facing, lipid bilayer of the plastid envelope. Either of the lipid bilayers that surround a plastid and form the plastid envelope. The double lipid bilayer enclosing a plastid and separating its contents from the rest of the cytoplasm; includes the intermembrane space. The outer, i.e. cytoplasm-facing, lipid bilayer of the chloroplast envelope. Penetrating at least one phospholipid bilayer of a plastid outer membrane. May also refer to the state of being buried in the bilayer with no exposure outside the bilayer. Located in a plastid outer membrane such that some covalently attached portion of the gene product, for example part of a peptide sequence or some other covalently attached moiety such as a GPI anchor, spans or is embedded in one or both leaflets of the membrane. Any constituent part of a plastid, a member of a family of organelles found in the cytoplasm of plants and some protists, which are membrane-bounded and contain DNA. Plant plastids develop from a common type, the proplastid. The outer, i.e. cytoplasm-facing, lipid bilayer of the chromoplast envelope. The external membrane of Gram-negative bacteria or certain organelles such as mitochondria and chloroplasts; freely permeable to most ions and metabolites. The lipid bilayer surrounding an organelle. Any constituent part of the living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
