how do I disable the photos I take on my Iphone to not show up on my IPad?

1. On your iPhone, you should activate iCloud Photos - this will upload all photos on the iPhone to iCloud, as long as there is sufficient space on iCloud.
2. On your iPad, you should deactivate iCloud Photos ... this will stop iCloud from pushing photos on iCloud to your iPad.

Note: Step 2 will also prevent any photos taken or saved on your iPad to be uploaded to iCloud.

By this arrangement, you will have iCloud and iPhone mirror each other wrt photos. (Your iPad will be left out)
