Label	Id	Description
thylakoid light-harvesting complex	GO_0009503	[A thylakoid membrane complex of chlorophylls a and b together with chlorophyll a-b binding proteins. In addition, LHCs contain a number of other proteins, the function of which is speculative, together with accessory pigments. The LHCs capture and transfer energy to photosystems I and II. An example of this is found in Arabidopsis thaliana.]
cell plate	GO_0009504	[The nascent cell membrane and cell wall structure that forms between two daughter nuclei near the center of a dividing plant cell. It develops at the equitorial region of the phragmoplast. It grows outwards to join with the lateral walls and form two daughter cells.]
chromoplast	GO_0009509	[A plastid containing pigments other than chlorophyll, usually yellow and orange carotenoid pigments.]
plastid chromosome	GO_0009508	[A circular DNA molecule containing plastid encoded genes.]
cytoplasmic chromosome	GO_0000229	[A chromosome found in the cytoplasm.]
plastid nucleoid	GO_0042646	[The region of a plastid to which the DNA is confined.]
transmitting tissue development	GO_0010500	[The process whose specific outcome is the progression of the transmitting tract over time, from its formation to the mature structure. The transmitting tissue is the tissue in the style of a carpel through which the pollen tube grows; it connects the stigma and the inside of ovary.]
gynoecium development	GO_0048467	[The process whose specific outcome is the progression of the gynoecium over time, from its formation to the mature structure. The gynoecium is the collective name for the carpels of a flower.]
cytochrome b6f complex	GO_0009512	[Complex that transfers electrons from reduced plastoquinone to oxidized plastocyanin and translocates protons from the stroma to the lumen. The complex contains a core structure of three catalytic subunits: cytochrome b, the Rieske iron sulfur protein (ISP), and cytochrome f, which are arranged in an integral membrane-bound dimeric complex; additional subunits are present, and vary among different species.]
cytochrome complex	GO_0070069	[A protein complex in which at least one of the proteins is a cytochrome, i.e. a heme-containing protein involved in catalysis of redox reactions.]
etioplast	GO_0009513	[A plastid arrested in the development of chloroplasts from proplastids due to absence of light or low light conditions.]
plasmodesmatal desmotubule	GO_0009510	[A tightly wound cylinder of membrane that is located within the plasmodesmal pore and runs the length of the plasmodesma. The desmotubule likely provides a rigid stability to plasmodesmata and confers a fixed diameter and pore size to the plasmodesmal canal, and is linked to the endoplasmic reticulum in each of the adjacent cell.]
plasmodesmatal endoplasmic reticulum	GO_0009511	[Endoplasmic reticulum found in plasmodesmata, junctions connecting the cytoplasm of adjacent plant cells.]
leucoplast	GO_0009516	[A colorless plastid involved in the synthesis of monoterpenes.]
glyoxysome	GO_0009514	[A specialized form of peroxisome that contains the enzymes of the glyoxylate pathway. The glyoxysome is found in some plant cells, notably the cells of germinating seeds.]
granal stacked thylakoid	GO_0009515	[Appressed thylakoid membranes that are part of a granum (stacked regions). A characteristic of these appressed regions is the preferential localization of photosystem II.]
chloroplast thylakoid	GO_0009534	[Sac-like membranous structures (cisternae) in a chloroplast combined into stacks (grana) and present singly in the stroma (stroma thylakoids or frets) as interconnections between grana. An example of this component is found in Arabidopsis thaliana.]
granum	GO_0009542	[Distinct stack of lamellae seen within chloroplasts. Grana contain the pigments, electron transfer compounds, and enzymes essential to the light-dependent reactions of photosynthesis.]
middle lamella	GO_0009519	[Layer of intercellular material, chiefly pectic substances, cementing together the primary walls of contiguous cells.]
polyamine homeostasis	GO_0010509	[Any biological process involved in the maintenance of an internal steady state of a polyamine.]
