Tomatoes are commonly grown from seedlings started indoors that are later transplanted into the garden. Tomato seeds are commonly planted indoors as early as 8 to 6 weeks before the average date of the last spring frost. Tomato seedlings are usually transplanted into the garden 1 to 3 weeks after the last frost. Wash tomatoes under cool running water.
Slice an "X" on the bottom of each tomato with a small utility knife. In a large saucepan bring water to a rolling boil. Fill a large mixing bowl with ice cold water. With a large spoon, place tomatoes in boiling water for 30 seconds to loosen skin. Remove tomatoes after 30 seconds, place directly into cold water to stop the cooking process. Core the tomatoes by removing the stem with a paring knife. Peel away the skin, being careful not to injure the flesh of the tomatoes.

The most probable and the most likely answer that you would get in asking this question would be domain.
As for stating it as a taxonomic group, it is more appropriate to refer to it as category, but there is no arguing that both words can be interchanged so just take that as a personal preference. Domain would be referred to in modern taxonomic category as the category that includes the kingdoms and all the other levels of the taxonomic hierarchy.
