To identify the exact source regions of coronal mass ejections (CMEs) and to understand the basic physical mechanisms involved in their initiation are amongst the major challenges of modern day solar physics. The Extreme-ultraviolet Imgaing Telescope (EIT) and Large Angle Spectrometric COronagraph (LASCO) aboard Solar and Heliospheric Observatory (SoHO) provides unique opportunity to study CMEs from 1.1 to 30 R&sun; since launch in December 1995. This thesis provides basic physical properties of EUV post-eruptive arcades (PEAs) observed by EIT at 195 Å and their role as tracers of source regions of CMEs. A detailed study of a specific EUV PEA event led to the discovery of a bright coronal inflow above the PEA. For specific PEA events line-of-sight magnetograms are analyzed to study the basic mechanism involved in CME initiation. Different varieties of evolutions in the photospheric magnetic field was detected during the time of CME eruption. We expect that the upcoming missions like STEREO and SOLAR-B will work in conjunction, helping us to understand the coupling between the photosphere and the corona.
