Expectation (purpose): Equipment, Tools, Organisms Used in Exercise: Results (attach page(s) with: observations, labelled diagrams) Answer the Following Questions: 1. In which Domain are algae, and protozoa classified? 2. In which Domain are cyanobacteria classified? 3. What are the three mechanisms of motility displayed by protozoa? 4. What macromolecule makes "red tides" red (see dinoflagellates on page 36)?-- 5. Algae are a diverse group of organisms that obtain their carbon requirements from oxygenic photosynthesis in which carbon dioxide is fixed in cellular materials (eg. carbohydrates) and water is split to provide oxygen. [True or False] (see page 38) 6. Plants, Algae and Cyanobacteria release oxygen during photosynthesis, Photosynthesis is also needed for carbon fixation. the general equation for photosynthesis is: Carbon Dioxide+ Water + Light Energy Carbohydrate + Oxygen. [True or False] 7. Cyanobacteria, is a phylum of bacteria that obtain their energy through photosynthesis. And play a critical role in the global cycle. They comprised part of the phytoplankton in oceans and as primary producers, are important in food chains in these habitats True or False] 11Page

Explanation / Answer

1) Algae and protozoa are classified in eukarya domain.

2) in bacteria domain , cyanobacteria is classified

3) protozoa can move by using structures known as flagella and cilia that will beat and propel them. they can also move by extending cytoplasmic extensions known as pseudopodia.

4)red tide is caused by micro algae bloom
