I have never heard of a yellwo ear turtle before. By chance, do you mean yellow belly turtle?
Depends if they're straight, bi or gay. Gay turtles cannot reproduce.
Why is my yellow belly turtle gasping and squeaking
they look mostly yellow and have black dots here and there
That type of turtle is called a spotted turtle, and the are endangered, or it is a painted turtle and it is most likely a painted turtle.
they will eat veggies or grass most of the time
unless there not enemies then yes.
That can describe a number of turtles, but most likely it is a variety of slider turtle. The yellow belly slider is common variety. See the related link for a picture.
The plastron is the part of the shell that faces the ground; it is the part protecting the turtle's abdomen. In the case of a yellow-bellied turtle such as a slider or cooter (as a hobbyist, I've had 2 MS yellow-bellied cooters in my life and I think they're great turtles), the plastron is in fact its yellow belly. Hope it helps.
