Need advise on Singular and Plural, thanks teachers!

With words like Fruit and Vegetable, do we put "s" after them?


For example, if I want to get people to guess a riddle by writing:


It feels heavy.
It looks like ( a kind of fruit or fruit or fruits????????)
It tastes juicy.

Guess a kind of (fruit or fruits?????)

If I want people to guess other riddles by giving clues such as:

Guess a kind of (dessert or desserts????)
(Vegetable or vegetables????)



Thanks for helping, teachers! ^o^

It looks like a fruit.

Guess which kind\sort of fruit it is.

Vegetable is often used in the plural, but would be singular here too.

Thank you, teacher Tdol! ^o^

The phrase a kind of will always take a singular noun. In such an instance you are talking about a general category.
