The nails and wire will be our test terminals for the potato battery. It does not matter which you start with, so pick any two to begin the experiment. Insert the ends about an inch deep into the potato and get them as close as you can without touching each other. (If they touch, no voltage difference will show and the meter will not move.
Multicellular organisms fall within three of these kingdoms: plants, animals and fungi. Kingdom Protista contains a number of organisms that may at times appear multicellular, such as algae, but these organisms lack the sophisticated differentiation typically associated with multicellular organisms.lthough many protists are single-celled, mulitcellular algae are sometimes placed within this kingdom alongside the single-celled algae. Differences between algae and plants include the lack of specialized body parts. Perhaps the most vivid example of multicellular algae lies in the kelp forests in some coastal areas.
6 The protist kingdom is made up of one-celled (unicellular) organisms and simple many-celled (multicellular) organisms. The nucleus of a protist's cell is enclosed in a nuclear membrane. Some protists, such as the one-celled amoeba and paramecium, feed on other organisms.
