We present the results of searches for large extra dimensions in samples of events with large missing transverse energy Ee{sub T} and either a photon or a jet produced in pp collisions at {radical}(s)=1.96 TeV collected with the Collider Detector at Fermilab II. For {gamma}+Ee{sub T} and jet+Ee{sub T} candidate samples corresponding to 2.0 and 1.1 fb{sup -1} of integrated luminosity, respectively, we observe good agreement with standard model expectations and obtain a combined lower limit on the fundamental parameter of the large extra dimensions model M{sub D} as a function of the number of extra dimensions in the model.
