Question

The grana and inter-grana in chloroplasts are made from thylakoids then why the colour of grana is green and intergrana is nongreen??

Answer 1

Answer:

because it also contains chlorophyll

Answer 2

Explanation:

Many thylakoids stacked together is called a granum (plural: grana). The thylakoids are green because this is where chlorophyll is stored. There is a watery liquid surrounding all of the stacks. This liquid is called stroma.

In this paper we simulate for the first time the propagation of green light through grana and inter-grana components of chloroplasts. Those components are nano-metric structures and thus regular estimation of the propagation of light cannot be exact without taking into account diffraction effects.
