### Description

We present the study of K0s and Lambda production performed with the ALICE experiment at the LHC in Pb-Pb collisions at sqrt(sNN)=2.76 TeV and pp collisions at sqrt(s)=0.9 and 7 TeV. The K0s and Lambda particles are reconstructed via their V0 decay topology allowing their identification up to high transverse momenta. The corresponding baryon/meson ratios as a function of transverse momentum are extracted for Pb-Pb collisions in centrality bins and in the transverse momentum range from 1 to 10 GeV/c. They are also compared with the ones measured in pp events at the LHC energies of 0.9 and 7 TeV as well as in Au-Au collisions at sqrt(sNN)=0.2 TeV from RHIC.
