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.
Protists were traditionally subdivided into several groups based on similarities to the higher kingdoms: the unicellular animal-like protozoa, the plant-like protophyta (mostly unicellular algae), and the fungus-like slime molds and water molds.any protists are flagellate, for example, and filter feeding can take place where the flagella find prey. Other protists can engulf bacteria and other food particles, by extending their cell membrane around them to form a food vacuole and digest them internally, in a process termed phagocytosis.
