In case of downward direction gravity helps to velocity weather the upward direction gravitational force opposes the moving velocity.
That's why the range of projectile on a downward inclined plane is MORE THAN the range on upward inclined plane for the same velocity of projection and angle of projection.

While moving upward gravitational force restricts the motion of the body on the other hand, while moving downward gravitational force help the body to move downward.
So with force range of projectile (body projected at a target with particular force, force for both upward and downward motion is same) increases.

It is so because work is done align with the action of gravity.

I think only velocity changes but not range. Distance remains same.

When projectile moves upward its velocity reduce because negative gravitational acceleration there for time increase to reach same height but time taken to reach the ground less due to ground. And distance (range) = v/t.
As t increases d reduce &t reduce d increase. There for distance (range) inversely proportional to time.

I think they will be of the same values even if the plane that is being his is inclined up or down. They will his only a particular point with respect to horizontal distance (i.e. Range).
But the height of impact will change depending on the inclination. Agree. ?

During downward projection from inclined plane, range=horizontal range from ground+some value.
During upward projection, range=horizontal range from ground-some value.
During upward projection, range=horizontal range from ground-some value.

In case of upward projection, object is moving against the gravity i.e. we can say velocity has to overcome the gravity for motion, but in case of downward motion the situation is totally opposite.
As we know that horizontal component of velocity remain the same during projectile but vertical component changes in case of upward motion vertical component is decreasing (to overcome velocity) casing the resultant velocity to decrease.
