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.
For the other species known by this name, see Nereocystis. Macrocystis pyrifera, commonly known as giant kelp or giant bladder kelp, is a species of kelp (large brown algae), and one of four species in the genus Macrocystis.
