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.
Kelp bass, giant kelpfish, garibaldi, norris' top snail, and kelp crabs are all common inhabitants of the kelp forest. Kelp anchors to the rocky bottom with a structure called the holdfast. The holdfast has many crevices and is home to many other animals such as spiny brittlestars and amphipods. The leaf-like kelp blades (also called fronds) provide a large surface area for photosynthesis. On the blades themselves, a bryozoan can grow rapidly and completely cover a kelp blade within 3-4 weeks.
