When ‘Tu aides moi’ becomes ‘aide-moi’, the ‘s’ in the verb ‘aide’ is lost, as in the other example sentences. Does that mean that in affirmative imperative sentences the verb is conjugated in the ‘il/elle/on’ form? 

Thank you!

She loves her parent,  versus, She loves her parents. I felt it should be 'Elle aime son parent" and in the plural, " Elle aime ses parents". I cannot understand why both reverso and google keep giving me the translation with 'ses" for BOTH forms.
