Qs about MANAGE CHANNEL Command

I know that MANAGE CHANNEL Command is used to close and open a logical channel.

Close a logical channel command:
00 70 80 XX (i.e. 01 02 03)

Open a logical channel command:
00 70 00 XX 00 (i.e. 00)

As far as I know, the only open logical channel by default is Basic channel.

Qs:
1. When and where must I use MANAGE CHANNEL Command?
2. When I send SELECT APDU through a close logical channel, will it open automatically or should I open it first?

A2: As far as I know, SELECT is defined to be an alternative for opening a logical channel
