Why does the Panama Canal have canal locks while the Suez Canal doesn’t have any?

Answer 1

The Panama Canal travels through some very challenging terrain, and so the canal would either need to raise/descend in elevation along with the terrain, or otherwise would need to be dug extremely deeply in some locations. They chose the lock method to raise and lower the canal sections as it moved through the elevation changes. The Suez canal doesn’t have these elevation changes and so could be dug at a consistent elevation without difficulty.
