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.
Call them protists. Perhaps it is easiest to consider the phyla: Chlorophyta (Green algae), Phaeophyta (Brown algae), and Rhodophyta (Red algae). There are others, such as blue-green algae, which are bacteria, and etc, but protist is considered correct enough, generally speaking.Protista is not a taxonomically correct clade. It is a paraphyletic grouping used as a term of convenience.here are others, such as blue-green algae, which are bacteria, and etc, but protist is considered correct enough, generally speaking.
