What happened to photos on Ipad and Iphone8 or any iphone?

Why do I have to click on camera to find photos that were downloaded or taken instead of the photo icon? Did apple take the photo icon away? Does anyone else experience this problem with their iphone?

The Photo app has been there from the start. Still is there.

The Photos app shows the pics in your camera roll as well as pics/vids you've synced over using iTunes and/or Photo Stream
