A granum (plural ~) 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 ~.

The thylakoid membrane is folded upon itself forming many disks called ~ (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 ~ (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 ~ry system, and widespread use of sericulture.

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

The flowers are showy, and the fruit is sometimes highly esteemed (see ~dilla, 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 ~. These ~ 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 ~, forms several structures called thylakoids. The thylakoids fill the chloroplast and an inter~ 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 ~.
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 "~" ...
