BIOS booting needs¹ a BIOS­Boot partition on a GPT disk.
It's not a BIOS boot­partition, because people use the
term boot­partition to mean a partition/filesystem that's
mounted at /boot.

I have just posted what it's for, so I won't repeat here.

UEFI booting needs to find an ESP somewhere. Which other special
partitions are required?

¹ There are risky ways of avoiding it, like putting the core image in
  a filesystem and praying that it doesn't ever get moved.
