With emerging evidence of quantum oscillations in photosynthesis comes the suggestion that there could be interaction between quantum oscillations and classical oscillations in photosynthetic bacteria and plants.

“It has been suggested that photosynthetic reaction centres exploit 2 varieties of molecular noise to maintain, rather than destroy, coherence:

•   White noise from normal molecular jostling of surround molecules such as water or metal ions.
•   Coloured noise which is the vibrations of large molecular structures within the chloroplasts, such as pigment molecules and the protein scaffolds that hold them in place (the pigment-protein complexes (PPCs)/

Both white and coloured noise appear to be exploited by photosynthetic reaction centres to help shepherd the coherent exciton to the reaction centre”.    Jim Al-Khalili 2014.

There are various forms of plant oscillations, and these can be modelled using reaction diffusion e.g biorhythms.

Are we seeing the "correspondence principle" in action?

“Bohr uncovered the remarkable fact that, despite these striking differences between the quantum and classical theories, there is nonetheless a deep relation between the quantum frequency, and the harmonic components of the classical motion....each allowed quantum transition is determined by the presence of a “corresponding” harmonic component in the electron’s classical motion; if a harmonic is missing from the classical motion, then that quantum transition is not allowed”.   Alisa Bokulich 2009.

Most of the transient states involved in the primary events of photosynthesis are paramagnetic, M K Bowman et al 1981. 

Both reaction diffusion and magnetically induced oscillations could potentially be modelled by the same equation.

“The standard form of the mean-field dynamo equation is similar to convection diffusion-reaction equations. In fact, it can be reduced to the famous Fisher-Kolmogorov-PetrovskiiPiskunov ~FKPP equation which has become a basic mathematical tool in the theory of propagating fronts travelling into the unstable state of the reaction-diffusion systems”. Sergei Fedotov 2002.

In this what sits behind a relationship between classical and quantum oscillations in magnetoreception and photosynthesis?

Forgot to say - this might also explain how photosynthesis is taking place at room temperature.

EM fields accelerate electron transfer, and appear to compete with the intrinsic chemical forces driving the reactions. M Blank 2001.

Scientists  have found that quantum entanglement can occur at high temperatures if systems are not in thermal equilibrium. A nonequilibrium state for two coupled, parametrically driven, dissipative harmonic oscillators could have stationary entanglement at high temperatures.  Fernado Galve et al 2010.    Also see G Manzano – ‎2013

Quantum entanglement between two field modes can be achieved through the collective squeezing of the two respective modes. If single-mode squeezing is performed prior to such a two-mode squeezing, an enhancement of entanglement production can happen. Interestingly, the occurrence of this enhancement can be implicitly linked to the local classical dynamical behavior via the paradigm of quantum–classical correspondence.   SK Joseph – ‎2014
