Key Concepts

Grana

Grana are stacks of thylakoid membranes within the chloroplast that appear as distinct granum (singular) structures. They are specialized for the light-dependent reactions of photosynthesis and are typically densely packed with photosynthetic pigments and proteins. Their stacked nature increases the surface area for light absorption.

Stroma Thylakoids

Stroma thylakoids, also known as lamellae, are unstacked thylakoid membranes that interconnect grana stacks. They function to facilitate the distribution of energy and material between grana and the stroma, ensuring an efficient flow of electrons and molecules during the light-dependent reactions. Their less ordered structure compared to grana allows them to serve as conduits for inter-grana communication.

Chloroplast Structure

A chloroplast is a plant organelle responsible for photosynthesis. It is composed of internal membrane systems embedded within a fluid matrix called the stroma. These membrane systems include thylakoids, which are the sites of the light-dependent reactions of photosynthesis, and they organize in distinct structural forms that optimize light absorption.
