The 19-year-old has previously gained experience on loan at Ebbsfleet and Yeovil, and will hope to be involved when Argyle travel to Southend this weekend.
Gozie, who was part of the Reading squad for the FA Cup tie with Crawley, is gaining similar experience to the likes of Jem Karacan and Alex Pearce at the club.
"Since I came back I've enjoyed being around the first team," Ugwu said on the club's website.
"It was a nice surprise to go straight into the first team at Crawley and it was good to get a run out at QPR too.
"If you look at the older boys such as Jem and Pearcey you see that they've gone out on loan.
"They've had their experience as I've been doing too. And if you look where they are now, you see that it's obviously helped them."
