Lesson 55
Plant-like Protists
| Question | Answer |
|---|---|
| Phytoplankton | mostly microscopic marine organisms that carry out photosynthesis |
| Algae | plant-like protists that carry out photosynthesis |
| Spore | one-celled asexual reproductive structures that can develop into an organism without uniting with another cell |
| Chlorophyta | also known as green algae, can reproduce asexually and sexually |
| Chrysophyta | group that contains diatoms, contain “glassy” cell walls that are formed into geometric shapes |
| Dinoflagellata | commonly known as the dinoflagellates, they have two flagella and can live in both freshwater and marine habitats, they can carry out photosynthesis |
| Red Tide | condition where certain red dinoflagellates reproduce and poison large areas of coastal waters |
| Phaeophyta | commonly known as brown algae, multi-cellular and the largest, most complex group of seaweed algae that live along rocky shores in cooler environments |
| Holdfast | root-like structure that anchors some brown algae to the sea floor |
| Rhodophyta | also known as red algae, they are the most plentiful variety of seaweed, they live in warmer waters |
| Euglenophyta | contains flagellates with chloroplasts, contain euglena |
| Euglena | a flagellated protist that can carry out both photosynthesis and eat other organisms- they are both heterotrophic and autotrophic |
