A granum (plural grana) is a stack of thylakoid discs. Chloroplasts can have from 10 to 100 grana. Chloroplasts can have from 10 to 100 grana. Grana are connected by stroma thylakoids, also called intergranal thylakoids or lamellae .
Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. [1]Within the stroma are grana (stacks of thylakoid), the sub-organelles where photosynthesis is started [2] before the chemical changes are completed in the stroma.
Within the envelope membranes, in the region called the stroma, there is a system of interconnecting flattened membrane compartments, called the thylakoids.The thylakoid membrane is quite similar in lipid composition to the inner envelope membrane, containing 78% galactolipids, 15.5% phospholipids and 6.5% sulfolipids in spinach chloroplasts.

Chloroplasts, containing thylakoids, visible in the cells of Rosulabryum capillare, a type of moss. A chloroplast (/ ˈ k l ɔːr ə ˌ p l æ s t,-p l ɑː s t /) [1] [2] is a type of organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells.
A teenager has been sentenced to 52 years in prison for fatally stabbing three girls at a children's Taylor Swift-themed event in the United Kingdom last year. Axel Rudakubana, 18, pleaded guilty ...
“Old vine” is a commonly used term in the world of high-end wine. It seems to imply something regal about a wine, a greater sense of depth, concentration or profundity of character.
Lamella, in cell biology, is also used to describe the leading edge of a motile cell, of which the lamellipodia is the most forward portion. [5] The lipid bilayer core of biological membranes is also called lamellar phase. [6] Thus, each bilayer of multilamellar liposomes and wall of a unilamellar liposome is also referred to as a lamella.
