- Golgi stack
The set of thin, flattened membrane-bounded compartments, called cisternae, that form the central portion of the Golgi complex. The stack usually comprises cis, medial, and trans cisternae; the cis- and trans-Golgi networks are not considered part of the stack.
- photoreceptor outer segment
The outer segment of a vertebrate photoreceptor that contains a stack of membrane discs embedded with photoreceptor proteins.
- host cell Golgi apparatus
A compound membranous cytoplasmic organelle of eukaryotic host cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack.
- granum
Distinct stack of lamellae seen within chloroplasts. Grana contain the pigments, electron transfer compounds, and enzymes essential to the light-dependent reactions of photosynthesis.
- obsolete Golgi apparatus part
OBSOLETE. Any constituent part of the Golgi apparatus, a compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack.
- granum assembly
A process that is carried out at the cellular level which results in the assembly of a granum. A granum is a distinct stack of lamellae seen within chloroplasts.
- cisternal progression
The process that results in the physical movement of a new cis-Golgi stack from the cis-position, nearest the endoplasmic reticulum (ER), to the trans position, farthest from the ER, successively becoming first a medial-Golgi cisterna and then a trans-Golgi cisterna.
- photoreceptor disc membrane
Stack of disc membranes located inside a photoreceptor outer segment, and containing densely packed molecules of photoreceptor proteins that traverse the lipid bilayer. Disc membranes arise as evaginations of the ciliary membrane during the development of the outer segment and may or may not remain contiguous with the ciliary membrane.
- cone photoreceptor disc membrane
Stack of disc membranes located inside a cone photoreceptor outer segment, and containing densely packed molecules of opsin photoreceptor proteins that traverse the lipid bilayer. Cone disc membranes arise as evaginations of the ciliary membrane during the development of the cone outer segment and remain contiguous with the ciliary membrane.
