Hint: The structure involved in photosynthesis is the image depicted in the question. This double-membrane enclosed organelle has a third membrane system called thylakoids, which can be two more forms, one is also known as integral thylakoid while the other is its disc stack.
Complete step by step answer:
Two structures of the chloroplast are grana and stroma. Grana is composed of a disc-like plate that is embedded inside the stroma, while on the other hand a jelly-like colorless matrix present inside the chloroplast is called matrix. A thylakoid is a compartment that is membrane-bound inside chloroplasts and cyanobacteria. The area between the membranes of the thylakoid is called the thylakoid lumen. They are the site of photosynthesis reactions that are light-dependent. Grana is related by integral or stroma thylakoids that combine the stacks to create a single functional compartment.
So, the correct answer is, ‘Stroma thylakoid, Grana thylakoid’.
Additional information: As it is present in the stroma, the Stroma thylakoid traps light energy for photosynthesis. Grana thylakoids (thylakoid stacks are referred to as grana).
- In botany, stroma refers to the colorless fluid inside the chloroplast covering the grana.
Grana (stacks of thylakoid) and sub- organelles or daughter cells are inside the stroma, where photosynthesis starts before the chemical changes in the stroma are completed.
- A granum (plural grana) is a thylakoid stack of discs. Chloroplasts may have between 10 and 100 grana. Grana are connected by stroma thylakoids. The distinct protein structure of Grana thylakoids and stroma thylakoids can be distinguished. Grana contributes to the wide surface area to volume ratio for chloroplasts.
Note: Photosynthesis occurs in the subcellular organelles known as the chloroplast in photosynthetic eukaryotes. It is the mechanism by which light energy is converted into chemical energy, resulting in the creation of organic compounds rich in oxygen and energy. Endosymbiotic theory suggests that chloroplasts and mitochondria (energy-producing organelles in eukaryotic cells) are descended from such organisms; photosynthetic cyanobacteria are free-living close relatives of chloroplasts.
