TL;DR
It is now clear that there is a dynamic continuum of organisation and function of the photosynthetic apparatus from the appressed granal and non-appressed stroma thylakoids within a chloroplast, to different chloroplasts within a leaf, to leaves within and between species.
Abstract
The photosynthetic apparatus of plants responds to changing light quantity and quality with coordinated changes in both the light-harvesting antennae of the photosystems and the amounts of electron transport components and ATP synthase. These compositional modulations are accompanied by changes in thylakoid membrane organisation and photosynthetic capacity. It is now clear that there is a dynamic continuum of organisation and function of the photosynthetic apparatus from the appressed granal and non-appressed stroma thylakoids within a chloroplast, to different chloroplasts within a leaf, to leaves within and between species. While it is very unlikely that there is a unique solution to photosynthesis in the sun or shade, substantial changes in composition, and hence thylakoid membrane organisation and function, are elicited as part of sun/shade responses.

It is concluded that phosphorylation of a population of the light-harvesting chlorophyll a/b protein complexes (LHC) in grana partitions causes the migration of these pigment proteins from the PS II-rich appressed membranes into the Photosystem I (PS I) enriched unstacked regions, which increases the absorptive cross section of PS I.

The ratio of photosystem I reaction centers to cytochrome b6/f complexes to photosystem II reaction centers is very nearly 1:1:1, and the pool of rapid donors of electrons to P700 includes not only the 2 reducing equivalents stored in the cy tochrome b 6/f complex but also those stored in slightly more than 2 molecules of plastocyanin per P700.

Pea plants (Pisum sativum) were grown under different irradiances and the photosynthetic characteristics and chloroplast properties were determined on young, fully expanded leaves and analysis of the CO2 response curves suggested that the ratio of electron transport capacity to RuP2 carboxylation capacity was greater for plants grown at higher irradiances than for plants growing at lower irradiances.

Following an increase of growth irradiance, pea leaves readily increase the capacity for utilising high light effectively, even when the total chlorophyll per unit leaf area remained constant, however, a better understanding of the time course of response requires measurements of other chloroplast parameters.
