Jam & Jelly, Affect & Effect

Jam & Jelly, Affect & Effect
 

What is the difference between jam and jelly?

affect and effect are completely different words, but I just want to know what each word means.

Gracias.

Jelly is made mostly from the juice of the fruit and has a gelatin-like texture. Jam has pureed fruit in it as well as the juice. Both are preserves (using pectin or sugars as a preservative).

Affect: to act on, to effect a change on/in someone/something
Effect: to bring about, to make happen, to accomplish
Both verbs have a corresponding noun, too.

thanks :D
