The cherry tomato is a type of small round tomato believed to be an intermediate genetic admixture between wild currant-type tomatoes and domesticated garden tomatoes. Cherry tomatoes range in size from a thumbtip up to the size of a golf ball, and can range from spherical to slightly oblong in shape. Although usually red, other colours such as yellow, green, and black also exist. Those shaped like an oblong share characteristics with plum tomatoes and are known as grape tomatoes.
