Why does stall speed increase in a turn?

Why does an airplane in a turn stall at a higher airspeed than an airplane in wings level flight?

Best approach to explaining this I’ve seen. Thank you!

Helps so much thanks

Can we use the rudder to maintain altitude during a turn ? Is this what is referred ad coordinated flight ?

[@nimbapilot6925]

This may be too late but the answers to your question is No. you cannot used to keep the aircraft coordinated. This will keep the aircraft from skipping and skidding; and potentially get yourself into stall spin situations depending on the maneuver you are doing. Rudder usage is very important during stall maneuvers.

@@nimbapilot6925 great thanks, so what does a coordinated turn mean ?
