A granum is a coin-shaped stack of thylakoids, which are the membrane-like structures found inside the chloroplasts of plant cells. Photosynthesis, or the process by which plants make their own food, occurs in the chloroplasts. Grana, or groups of granum, are connected by way of stromal thylakoids.
Also What is a granum Class 11?
Granum are stacks of membrane-bounded, flattened discoid sacs called thylakoids containing the molecules of chlorophyll. – Light reactions of photosynthesis are performed in granum while dark reactions are performed in the stroma.
Subsequently, What is grana Class 9? 1)Grana(site of light reaction):It is a stack of membrane bounded,flattened discoid sac containing the molecules of chlorophyll. 2)Stroma(site of dark reaction):Homogeneous matrix in which grana are embedded. They contain photosynthetic enzymes,DNA,ribosomes.

What is thylakoid and granum?
Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. … Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum). Grana are connected by intergranal/stromal thylakoids, which join granum stacks together as a single functional compartment.

What is the difference between thylakoid and granum?
Grana are found in the stroma of the chloroplast, which is connected by stroma thylakoids. The main difference between grana and thylakoid is that grana are the stacks of thylakoids whereas thylakoid is a membranebound compartment which is found in chloroplast.
What is thylakoid in plants?
A thylakoid is a sheet-like membrane-bound structure that is the site of the light-dependent photosynthesis reactions in chloroplasts and cyanobacteria. It is the site that contains the chlorophyll used to absorb light and use it for biochemical reactions.
What are thylakoids?
Thylakoids are usually arranged in stacks (grana) and contain the photosynthetic pigment (chlorophyll). The grana are connected to other stacks by simple membranes (lamellae) within the stroma, the fluid proteinaceous portion containing the enzymes essential for the photosynthetic dark reaction, or Calvin cycle.

What is difference between thylakoid and grana?
Thylakoids are the number of flattened sacs inside a chloroplast, bound by pigmented membranes on which the light reactions of photosynthesis take place. Grana are the stacks of thylakoids organized inside the stroma to increase the surface area for light dependent photosynthesis.
