Stroma may refer to:
Stroma, Scotland, an island off the northern coast of Scotland in the Pentland Firth
Stroma (animal tissue), the connective, functionally supportive framework of a biological cell, tissue, or organ ...
Stroma can refer to:
1) The connective supportive framework of a biological cell, tissue, or organ.
2) The fluid filled area of a chloroplast outside of the thylakoid membranes wherein the light-independent reactions (Calvin Cycle and Carbon ...
Ovarian stroma
[L. ovarium - ovary; Gr. stroma - something laid out to build or lie upon]. The structural framework of the ovary that is formed by connective tissue and smooth muscle.
stroma
[Gk. a bed, from stronnymi, to spread out]
The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water.
stromatolite ...
stromatolite A sedimentological and biological "fossil" representinmg colonies of bacteria altenating with layers of sediments.
stroma. A compact, usually spore-producing structure formed from fungal mycelium on the surface of a host.
Stromatoporoids, once thought to be coral, but actually sponges, continued their significant role in Silurian reefs. Some stromatoporoid specimens are over 16 feet in diameter.
stroma thylakoid A thylakoid that does not occur in a granum; connects separate grana.
stroma The matrix between the grana in chloroplasts and site of the dark reactions of photosynthesis.
D stroma, cytochromes
E antenna complexes, reaction centers
...
The stroma is a peculiar soft tissue, abundantly supplied with bloodvessels, consisting for the most part of spindle-shaped cells with a small amount of ordinary connective tissue.
A normalized, subtracted (against a stromal cell cDNA library) cDNA library was generated from these cells. A similar strategy was adopted in the construction of a stromal cell library.
Enclosed by the chloroplast membrane is the stroma, a semi-fluid material that contains dissolved enzymes and comprises most of the chloroplast's volume.
We know this based on the presence of stromatolites - fossilized microbial mats consisting of layers of filamentous prokaryotes - and trapped sediment that date back to that time.
The stroma is an area inside of the chloroplast where reactions occur and starches (sugars) are created. One thylakoid stack is called a granum. The thylakoids have chlorophyll molecules on their surface.
Used to pump H+ from stroma into thylakoid space
By active transport and electrochemical gradient
H+ conc in thylakoid space > stroma
H+ ions pass back from space between two mitochondrial membranes ...
The energy released as electrons pass down the gradient between photosystem II and photosystem I is harnessed by the cytochrome b6/f complex to pump protons (H+) against their concentration gradient from the stroma of the chloroplast into ...
(Science: zoology) dollar fish, a fish of the united states coast (Stromateus triacanthus), having a flat, roundish form and a bright silvery luster; called also butterfish, and lafayette. See butterfish.
The fluid-filled space surrounding the grana is the stroma. Many enzymes needed in photosynthesis are found embedded in the thylakoid membranes and in the stroma.

Phycobilins are water-soluble pigments, and are therefore found in the cytoplasm, or in the stroma of the chloroplast. They occur only in Cyanobacteria and Rhodophyta.
Specifically, some rocks from Australia called the Warrawoona series give evidence of bacterial communities organized into structures called stromatolites. Fossils like these have subsequently been found all over the world.
They utilize the products of the light reactions, ATP and NADPH to reduce carbon dioxide and to make glucose and the more complex middle sized biomolecules. The enzymes that carry out these reactions are in the stroma (fluid) portion of the ...
This energy is used to convert water plus atmospheric carbon dioxide into metabolizable sugars by the biochemical process of photosynthesis. Chloroplasts have a double outer membrane. Within the stroma are other membrane structures - the thylakoids.
of the placenta upon implantation into the endometrial epithelium of the uterine wall. A portion of cytotrophoblast cells (near the inner cell mass) form the highly invasive syncytiotrophoblast which penetrates into the endometrial stroma.
