3. Students practice reading a thermometer. Explain that room temperature is about 70Â°F. Using your transparency and a red marker, color the bulb and column part of the âtubeâ up to the 70Â°F mark. Let students ï¬ nd the 70Â°F mark on their page and use a red colored pencil to color up from the bulb to that mark.
The majority of organisms classified as protists are unicellular though there are a few multicellular organisms. For example, kelp (âseaweedâ) is technically a protist even though it is multicellular. Kelp is not grouped with plants, however, because it lacks the cellular complexity present in plant cells.
Pacific Kelp Forest Urchins. Photo by Paul Banko. This lovely photograph shows the three common urchins found in eastern Pacific kelp forests. Red = Strongylocentrotus franciscanus; Purple = Strongylocentrotus purpuratus; White = Strongylocentrotus droebachiensis.ereocystis luetkeana often dominates northeastern Pacific kelp forests. It has a long stipe that is attached often to a small rock and is kept aloft by a gas-filled float. The fronds extend from the float. This makes for a very unstable arrangement and strong storms often uproot the plant.
