What are grana lamellae?

The region of the stroma that interconnects the thylakoid stalks are called as stromal lamellae which is present in stroma region. The region in between the grana are called as grana lamellae which is present in grana region.

What is the relationship between grana and thylakoids?

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 membrane-bound compartment which is found in chloroplast.

Is stroma thylakoid and stroma lamellae same?

Yes, both stroma lamella and stroma thylakoids are same. The thylakoids of different grana are connected by stroma thylakoids, also called intergranal thylakoids or lamellae.

How are thylakoids different from Stromas?

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.

Are grana lamellae and stroma lamellae same?

The region of the stroma that interconnects the thylakoid stalks are called stromal lamellae which are present within the stroma region. The region in between the grana is named grana lamellae which are present within the grana region.

What is the difference between grana and lamellae?

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 are stacks or grana connected to each other by?

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.

Why are thylakoids stacked into grana?

It is the site of a light-dependent process of photosynthesis. Thylakoids are arranged in stacks of disks called granules present on the surface of the stroma. Thus, when thylakoids are stacked, it increases the surface area which allows more electron transport chains to be embedded into the thylakoid membrane.

Are thylakoids lamellae?

Thylakoid membranes are actually a system of lamellar membranes working together, and are differentiated into different lamellar domains. The basic unit of the membrane system is a flattened single vesicle called the thylakoid; thylakoids stack into grana.

Where are thylakoids and grana located?

chloroplast
The chloroplast contains chlorophyll within its thylakoids, which absorbs light energy and gives chloroplasts its green color. Stacks of thylakoids are known as grana, which exist in the open space of the chloroplast known as the stroma.

Do thylakoid membranes form grana?

Chloroplasts contain a system of membrane sacs, the thylakoids, some of which are stacked to form grana (singular, granum), whereas others float freely in the stroma. It is on the thylakoid membranes that the electron carriers necessary for photosynthesis reside.

What are grana thylakoids?

A granum (plural grana) is a stack of thylakoid discs. Chloroplasts can have from 10 to 100 grana. Grana are connected by stroma thylakoids, also called intergranal thylakoids or lamellae. Grana thylakoids and stroma thylakoids can be distinguished by their different protein composition.
