Detailed explanation-1: -Chloroplasts contain a system of membrane sacs, the thylakoids, some of which are stacked to form grana (singular, granum), whereas others float freely in the stroma. It is on the thylakoid membranes that the electron carriers necessary for photosynthesis reside.
Detailed explanation-2: -A granum is referred to as a stack of 20-100 thylakoid units. Found in more complex plants. Grana are connected to each other by stromal lamellae. Thylakoid membranes of granum contain photosynthetic pigments and enzymes. A granum is the site for the light reaction of the photosynthesis.
Detailed explanation-3: -Thylakoids, containing chlorophyll and other accessory pigments (red, orange, yellow, brown), are in stacks called granum (grana, plural).
