Answer:
1. Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis.
Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum).
2. A granum is a coin-shaped stack of thylakoids, which are the membrane-like structures found inside the chloroplasts of plant cells. Photosynthesis, or the process by which plants make their own food, occurs in the chloroplasts. Grana, or groups of granum, are connected by way of stromal thylakoid
3.Stroma (fluid) -Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma.
4. Lumens (denoted by lm) are a measure of the total amount of visible light (to the human eye) from a lamp or light source. The higher the lumen rating the “brighter” the lamp will appear.
5.A lamella refers to a thin layer, membrane, or plate of tissue. This is a very broad definition, and can refer to many different structures.
All the thylakoids of a granum are connected with each other, and the grana are connected by intergranal lamellae.
