"Do you have carrots?"

Translation: У вас є морква?

[ManuelHent1]

Should it not be "моркви"? It's plural, and "морква" is singular.

[matanov]

It's a mass noun (e.g. like "fruit" in English).

[Khrystyna507081]

Чи ти маєш моркву?

[Carl_Ramrod]

Is the "є" optional in this sentence? Could you just ask "У вас морква?"
