"and" is a co-ordinating conjunction used to connect two Independent clauses. How about this:
He went to the market, and attended to the daily chores.
One Independent clause: He went to the market
What is the other Independent clause? Is "attended to the daily chores" an Independent clause? In other words, is "he" implied in the second half of the sentence?

(1) I believe that many teachers would say that there is only one independent clause.
It has a compound predicate (the subject does two things):
He went to the market and attended to his daily chores. (NO comma, please.)
(2) If you wanted to change it to a compound sentence (two independent clauses),
you would need a conjunction and a comma:
He went to the market, and he attended to his daily chores.
NOT A TEACHER.
"Avoid using a comma to set off the second part of a compound predicate (two or more verbs sharing a single subject). In general, use a comma only if it is needed to avoid a misreading." (Source: Bryan A. Garner)
