Hi
We use every + [singular noun] + [singular verb] to talk about all the individual members in a group of things or people
Every film by Humphrey Bogart is a classic
Every report he writes is quite interesting to read
Every glass in that cabinet has a crack or chip
* We use all + [plural noun] + [plural verb] to talk about all an entire group of things or people.
When you want to talk about a specific group, you can use All of the
All films have a musical soundtrack
All of the films by Steven Spielberg are exciting
All glasses are delicate, and need to be handled with care
All of the glasses in that cabinet have a crack or chip
Note the difference between every + [time] and all + [time]x
Every morning I eat yogurt and cereal
(every morning means, Monday morning, Tuesday morning, etc)
I work hard all morning
(all morning means from the time I wake up until noon)
