  2. Jellies are plankton • Shortcut to moonjellyfmoon_jellyfis • Shortcut to thimblejelthimble_jelly

  3. An Example of a net

  4. Making a plankton net • Use a needlepoint hoop or other object to hold net open on the wide end • Use a nylon stocking as the net. Fit it over the hoop and secure in place • Cut the toe of the stocking and fit over a jar, save the lid to return the water sample to the classroom • Secure the jar to the stocking with a rubber band • Use 3 long pieces of string tied to the hoop so you can drag it through the water

  5. Plankton • comes from the Greek word for "wandering."  • diverse group of plants and animals that spend some or all of their life cycle drifting in the water of oceans or lakes. • are generally unable to move independently of currents and waves.

  6. Classification Zooplankton Animal or animal -like Phytoplankton plant or plantlike Photosynthesize

  7. Phytoplankton Phytoplankton are the base of the ocean's food web and are the food source for zooplankton. • are organisms that float on or near the surface of the water. • Most are rounded and single-celled. • All phytoplankton use photosynthesis for their energy • The most common phytoplankton are diatoms and dinoflagellates. Diatoms • single-celled algae. • join together in long chains. Dinoflagellates • small organisms with two tails or flagella. • all kinds of shapes and sizes. • Some have shells and some don't. • Not all dinoflagellates rely only on photosynthesis for all their energy. Some wrap themselves around food and absorb it. • Some dinoflagellates can make light using bioluminescence. Other types of phytoplankton Phaeophyta (brown algae) Cyanobacteria (blue-green algae) They photosynthesize, but some also use nitrogen for their energy. They are nitrogen fixers. They change free nitrogen into nitrates which are used by the cyanobacteria and by other plants in the ocean.

  8. Zooplankton • Zooplankton are • ocean animals that don't swim at all or are very weak swimmers • they drift or move with ocean currents • They can be found in the sunlit zone and in deep ocean waters • Zooplankton range in size from tiny microbes to jellyfish, Zooplankton-Classification by life stage • Holoplankton • planktonic their entire lives • Meroplankton • spend only a part of their life cycle in the water column, usually as a larval stage.
