I think it would be a mistake to save sweetcorn seeds as they are probably a hybrid seed. What you would get is a rather boring sweetcorn, when I presume you were trying to grow a 'super-sweet' one.
The photo you have at the top is the male tassel. It hasn't been a good year for ripening corn, did you get any?
Beetroot seed will also, I suspect, be a hybrid and not at all what you would like to eat. Buy packets until you are more experienced, otherwise you will waste your time, money and energy growing inferior vegetables.
