There is quite a big difference between a barred spiral galaxy and an elliptical galaxy.
The image attached below shows a barred spiral galaxy, NGC 2217. In barred spiral galaxy there is large bar like structure across the core of the galaxy , and on the terminal end there are the spiral arms of the galaxy. It is believed that the bar plays a role of material transportation to the core. The bar funnels in the surrounding material toward the SMBH at the core. The arms of the barred spiral galaxy often host high star formation rate as seen in the image below. The bar is often consist of dust and old stars.Where as in elliptical galaxy, the galaxies are somewhat diffused and also they don’t host much of the new stars. Elliptical galaxies are often unbounded. Elliptical galaxies are believed to be formed from several mergers and that’t the reason for their inability to form new stars.
Hope it will help
I know this is very big answer
