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 plants can only grow in cold ocean water that is not too deep and has lots of nutrients. Kelp plants only grow around a few islands and along a few coasts in the world. The giant kelp in food is called algin. Algin is a special substance that comes from giant kelp plants.iant kelp does not grow from seeds. Giant kelp grows from tiny cells, called spores. (Ferns are land plants that also grow from spores and not seeds.) Each giant kelp plant can release 70 trillion spores every year! These spores grow tiny plants that you can only see with a microscope.
