Why do thylakoids stack?
It is the suitable of a light-dependent train of photosynthesis. Thylakoids are arranged in stacks of disks named granules at_hand on the surface of the stroma. … excitement when thylakoids are stacked it increases the surface area which allows good-natured electron bear chains to be embedded inter the thylakoid membrane.

What does the stroma do?
Stroma: The fluid of the chloroplast surrounding the thylakoid membrane implicated in the synthesis of inanimate molecules engage carbon dioxide and water. Thylakoid: A flattened membrane sac within the chloroplast abashed to change perch energy to chemical energy.
What are thylakoids in chloroplasts?
The thylakoid membranes of a chloroplast is an inner method of interconnected membranes that carry out the perch reactions of photosynthesis. They are arranged inter stacked and unstacked regions named grana and stroma thylakoids respectively that are differentially enriched in photosystem I and II complexes.
What is the stroma in biology?
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 since photosynthesis is commenced precedently the chemical changes are completed in the stroma.
