A blender is designed to blend liquids, or puree soft foods with a lot of liquid content. A food processor performs multiple functions like slicing, grating, chopping and kneading, and can handle foods that are harder in texture.
A blender is primarily used to make soups, smoothies, sauces, dips and cocktails. Blenders mainly puree soft food, but a strong blender can also crush ice and coarsely chop or powder nuts.
A food processor performs specific multiple functions, such as chopping, grating, slicing, pureeing, kneading dough for bread or pastry, and making nut butter.
A blender usually has only one blade. The same blade is made to perform a limited set of functions by varying speed. While settings like chop and ice crush may fine-tune blending, the output may vary in texture (depending on the input), but will have little or no form. Blenders are mostly designed to blend liquid or soft foods into puree.
A food processor on the other hand can perform several additional functions. It comes with a set of different types of blades, each one for a specific function. The processor can slice, chop and grate vegetables, and the output has a very defined form. Food processors can also knead dough for bread or pastry.
edit Form and Texture of Processed Food
The food processed in a blender can have different textures, but is mostly amorphous.
The food prepared in a food processor usually has a definite form according to its function (slices, shreds, diced etc.).
