A granum (plural grana) is a stack of thylakoids in the chloroplast, an organelle found in plants and eukaryotic algae where photosynthesis takes place. Chloroplasts can have from 10 to 100 grana.

The thylakoid membrane is folded upon itself forming many disks called grana (singular = granum).
The "cytoplasm" of the chloroplast is called the stroma
The photosynthesis reactions can be broken down into two components: ...

The light reactions of photosynthesis occur in the grana (thylakoid membranes) of the chloroplasts of eukaryotic cells.

Records from the Warring States (481 BC-221 BC), Qin Dynasty (221 BC-207 BC), and Han Dynasty (202 BC-220 AD) provide a picture of early Chinese agriculture which included a nationwide granary system, and widespread use of sericulture.

One individual stack is called a granum, collectively these stacks of discs are called grana. Now one disk within this granum is called a thylakoid, so the grana are made up of stacks of thylakoid membranes.

The flowers are showy, and the fruit is sometimes highly esteemed (see granadilla, and maypop). The roots and leaves are generally more or less noxious, and are used in medicine.

PHOTOSYNTHESIS CHLOROPLAST STRUCTURE: Double membrane enclosing stacks of green disc like structures called grana. These grana make up what is called the thylakoids. These thylakoids are surrounded by a dense fluid called the stroma.

Inside the organelle the formative unit is called the granum, a coin-shaped structure that, piled with others grana, forms several structures called thylakoids. The thylakoids fill the chloroplast and an intergrana membrane permeates the interior of the organelle.

The interior of the thylakoids forms another compartment, the thylakoid space.
Thylakoids may be stacked into columns called grana.
Chlorophyll is located in the thylakoids.

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. Thylakoids appear in stacks called "grana" ...
