Vegetables don't have seeds on the outside, and strawberries don't have that anyways. Each "seed" on the outside of a strawberry is actually a fruit that contains a single seed. If you look carefully with a magnifying glass or something similar, you can often still see the female parts of the flower (pistil) sticking up from each "seed." The fleshy and sweet part of a strawberry originates as part of the flower called the receptacle. It sits below the ovaries of the flower. In strawberries, the receptacle is cone shaped, probably an adaptation to increase access by pollinators. After pollination, this part of the flower swells up and becomes the strawberry that you are familiar with :) The little ring of green leaves at the top of of a strawberry are the sepals of the flower it originated from.

This depends on the perspective you want to take. From an anatomical perspective, the fruit part of the strawberry is different from the fruit part of a grape.

From an economic perspective, they are the same; the sweet and fleshy material is the payment from the plant to the animal for doing the plant a service. The seed is something that the animal doesn't want but consumes anyway as part of the deal.
