Grapes are best defined as what type of fruit?

Grapes are best defined as small round fruit because they are typically small, spherical, and varying in size, usually around 1 to 5 centimeters in diameter. This characteristic is a defining trait of grapes, which can also come in various colors such as green, red, and black. Their round shape, along with their relatively small size, distinguishes them from other types of fruits that might be longer or of a different shape. This definition encompasses the essential physical attributes that accurately classify grapes, making "small round fruit" the most fitting description. Other choices fail to encapsulate the essential characteristics of grapes, which include their size and shape.
