Explanation:

• The PD, 'pendown and PU', 'penup commands' tell the turtle to leave ink on the screen as it moves or not to leave ink, respectively.
• The PU command lifts the turtle's pen so that, it does not draw a line while moving.
• The PD command puts down the turtle's pen so that it starts drawing again while moving. The PD command is only issued after the PU command has already been used.
