What is stroma plant?
Stroma: The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water. Thylakoid: A flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy.
What is stroma and grana?
Grana are the sites for the light reaction of photosynthesis. The grana of the chloroplast are disc-like plates, which consist of a pigment system made up of chlorophyll-a, chlorophyll-b, carotene and xanthophyll. Stroma. Stroma is the site for the dark reaction of photosynthesis.
What function is stroma?
The main function of stroma cells is to help support organs and act as connective tissue for particular organs. The connective tissue here connects to the parenchyma cells of things such as blood vessels and nerves. The stroma cells will help to reduce stress over the organ.
What is stroma short answer?
It refers to the colourless fluid inside the chloroplast covering the grana which are arranged inside it in the form of disc-like plates.
What is the structure of stroma?
Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma.
What is definition granum?
Definition of granum : one of the lamellar stacks of chlorophyll-containing thylakoids found in plant chloroplasts.
What is produced in the stroma?
ATP and NADPH are produced on the stroma side of the thylakoid membrane, where they can be used by the Calvin cycle.
What is the shape of stroma?
The stroma of the ovary is a unique type of connective tissue abundantly supplied with blood vessels, consisting for the most part of spindle-shaped stroma cells. These appear similar to fibroblasts. The stroma also contains ordinary connective tissue such as reticular fibers and collagen.
What is stroma and thylakoid?
Thylakoid vs Stroma Thylakoid is a membranous organelle present in the chloroplast. Stroma is the cytoplasm of the chloroplast. Function. Thylakoid provides necessary factors and conditions to initiate the light-dependent reaction of photosynthesis.
What’s the meaning of Rubisco?
Ribulose bisphosphate carboxylase/oxygenase (Rubisco) is a key enzyme in photosynthesis catalyzing corbondioxide fixation.
What is stroma made up of?
Stromal tissue is primarily made of extracellular matrix containing connective tissue cells. Extracellular matrix is primarily composed of ground substance – a porous, hydrated gel, made mainly from proteoglycan aggregates – and connective tissue fibers.
What is stroma composed of?
The stroma contains fibroblasts, collagen, blood vessels, lymph vessels, nerves, and adipocytes.
Is stroma a plant cell?
What is the difference between thylakoid and stroma?
Thylakoid is a membranous organelle present in the chloroplast. Stroma is the cytoplasm of the chloroplast. Thylakoid provides necessary factors and conditions to initiate the light-dependent reaction of photosynthesis. The light-independent reaction of photosynthesis is taken place in the stroma of the chloroplast.
