Cell Membrane and Transport
... Molecules and ions are in constant motion. In gases and liquides they move freely. As a result of their random motion, each type of molecule or ion tends to spread out evenly within thespace available. This is diffusion. Diffusion results in the net movement of ions and molecules from a high concent ...

Thylakoid
A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum). Grana are connected by intergranal or stroma thylakoids, which join granum stacks together as a single functional compartment.
