the science calorie (little c) is a measure of heat energy the food calorie (big C) is a measure of energy that we burn, but it is equal to 1,000 science calories so 1 big C is equal to 1,000 little c's.
Protists are a group made up of protozoa, unicellular algae, and slime molds. We will concentrate on the animal portion of this group: the protozoa (proto = first, zoa = animals).
Unicellular organisms are composed of a single cell, unlike multicellular organisms that are made of many cells. This means that they each live and carry out all of their life processes as one single cell. Most unicellular organisms are microscopic; however, some are visible to the naked eye.xamples of Unicellular Organisms. All prokaryotes, most protists, and some fungi are unicellular. Some of these organisms do live in large colonies, but each individual cell is a simple living organism. Let's look at some examples of unicellular organisms. Valonia ventricosa is a protist.
